Abstract

Korean investment in the ASEAN Region has grown tremendously during the last three decades, following the importance of Japanese investment in the same region. This is partly due to a favorable domestic growth in the Korean economy as stimulated by a successful agricultural reform and rural development on which industrialization takes place. Korea transformed itself from an underdeveloped, agricultural-based economy, into an industrialized country in Asia only within a very short span of time.This paper is aimed at assessing the spatial patterns and effects of Korean investment in Indonesian regional development before to the crisis. To achieve this general objective, an account on the general pattern of Korean investment is discussed from global level, Asia, ASEAN and Indonesia. Finally, an account for the spatial patterns and effects of Korean investment on regional development in Indonesia is presented.The paper is based on secondary data analysis. Data are gathered from various websites related to foreign investment in Indonesia as well as publications of various government organization for the spatial patterns and impacts of Korean investment. Data are analyzed using a simple descriptive statistics and thematic mapping.The research reveals that Korean investments in the world are mainly directed to USA, Europe and Southeast Asia. Southeast Asian Region has been the most important destination of Korean investment in the last three decades due to the availability of cheaper labor force, abundant natural resources, and favorable climate for investment and with little exception political stability. Recent investments are also directed to more capital intensive and more advance technology, thus facilitating the transfer of technology_ The distribution of Korean investment in Indonesia as any other foreign investments tends to be clustering in the surrounding areas of Jakarta, known as the Bogor, Tangerang; Bekasi (BOTABEK) Region where some 65 percent of foreign investment is located.. The effects of Korean investment on regional development at national level in Indonesia are very limited, but there is a substantial effect on the regional production structure, economic growth and employment generation at local-regional level, more especially in the main industrial agglomeration of the BOTABEK Region.

Abstract

The main objective of this research is to define the mechanism model of chemical reactions, which are responsible to the spatial distribution of water quality along flowpath using inverse modeling technique. in addition, the Saturation Indices (SI) analysis was used to characterize the effect of geological condition toward dissolved constituent within the groundwater: Moreover, Mass Balance Modeling code was employed to describe the stoichiometry and hydrogeochemical processes along flowpath.Field survey was carried out in order to obtain the data of hydraulic head and electrical conductivity to construct flownets and tentatively illustrate the spatial distributions of shallow groundwater quality. Next, the flow line was applied to define the sampling position of groundwater and aquifer mineral. Laboratory analysis was conducted to identify the main phases and constrains of dissolved constituent within the groundwater. Afterwards, the application of NETPATH 2.1.3 and Phreeqc Interactive 2.8 for Windows software aid to model the Mass Balance Calculation in order to account the prevailing hydrogeochemical reactions.The result shows that firstly, the aquifer within the research area can be grouped into several aquifer systems (i.e. denudational hill, colluvial plain, alluvial plain, and beach ridges) from recharge to discharge which generally have potential groundwater resources in terms of the depth and fluctuation of groundwater table. Secondly, flownets analysis gives three flowpaths that are plausible to be modeled in order to describe their hydrogeochemical reactions. Thirdly, the Saturation Indices (SI) analysis shows that there are a positive correlation between the mineral occurrence and composition and the value of SI from recharge to discharge. In addition, The Mass Balance Model indicates that dissolution and precipitation of aquifer minerals is dominantly change the chemical composition along flowpath and the rate of the mass transfer between two wells shows a discrepancy and be certain of the percentage of the nature of aquifer mineral. Lastly, there is an interesting characteristic of mass balance chemical reaction occurs which is the entire chemical reaction shows that the sum of smallest mineral fmmol/litre) will firstly always totally be reacted.

Abstract

This paper examinie the channels of petroleum distribution in Nigeria from the Refineries to Depot and Retail Outlets/Service Stations where the consumers finally purchase their products. Specifically the paper considers some of the geographical factors that are influencing the location of service stations in the Nigerian Petroleum Industry.

Abstract

The study area is located in the Sant'arcangelo region, Southern Italy. The area was developed from late Pliocene to middle Pleistocene in the southern part of the Apenines chain. It has also been defined as a piggy back basin filled with siliciclastic deposits, controlled by sedimentary tectonic activity.This article aims to identify the geological condition and generating geomorphological map for San Lorenzo area using aerial photo (scale 1:15000) and Panchromatic SPOT image (Scale 1:66000). Image interpretation was also done to identify morphological, structural and processes.The Sant'Arcangelo region is composed of 4 cycles both marine and continental in origin, all deposited on different environments: The Caliandro, Agri, San Lorenzo and Sauro cycles. The study area consists of Sauro and San Lorenzo Cycle. Sauro Cycle is Comprises of three heterotrophic units deposited in sintectonic discordance over the Agri cycle. San Lorenzo Cycle lying in unconformity over the precedent cycles is consisting of three units, namely conglomerates on the base part as well as on the top part of the sequence, and silty clays in the intermediate part. They form a syncline structure which ax has a NW-SE direction. The main structural features are represented by the San Lorenzo syncline and the Alianello fault. The San Lorenzo area has three principal origins: alluvial, denudation, and structural. Due to the geological-tectonic complexity, the structural landform is normally found as structural denudational landform. San Lorenzo area comprises of 41 landform units, namely 3 units of alluvial landforni, 26 units of denudational landform and 11 units of structural denudational landform.
