  • Sub Saharan Africa (SSA) is receiving increased investments in the energy sector under the belt and road initiative (BRI) project since its inception in 2013. SSA has a worse energy efficiency ratio coupled with deficient electricity access, through analysis showed varied impacts on the SSA countries due to the BRI initiative. This study dilves into the influencing factors for Energy Efficiency (EE) in 38 SSA countries, applying the probit and logit approach for 2000-2018. The Multiple-regression model shows significant results of some variables such as foreign direct investment, gross domestic product, and port infrastructure quality being significant on EE under BRI initiative countries. However, the logit and probit models produce similar results and the marginal effect for the entire variable, except energy imports that do not likely impact EE. Furthermore, the interaction of quality of port infrastructure and foreign direct investment variables produces significant results, highlighting the increased investments SSA receives under the BRI initiative in the energy and transport sectors. The model Percent correctly predicted (PCP) value was about 84%, indicating it correctly classified the variables and about 16% not classified. The study recommends EE performance standards should be incorporated on energy projects in SSA to ensure that these projects are energy efficient and decouple SSA's energy demand from economic growth. The research proffers suggestions for policy regarding the BRI initiative in SSA and the implications on sustainable energy and building a community with a shared future.

  • The aim of this study was to examine determinants of secondhand Bulk carrier and Oil tanker prices. This study compiled S& P transaction data taken from the Clarksons Research during J anuary 2018 to April 2022 to see how independent variables influenced secondhand ship prices. In the secondhand ship pricing model of entire segments, size, age, and LIBOR showed significant effects on prices. A vessel built in J apan and Korea was traded at a higher price than a vessel built in other countries. In the bulk segment, size, age, Clarksea index, LIBOR, and inflation were meaningful variables. In the Tanker segment, unlike Bulk carrier, only size and age were useful variables. This study performed regression analyses for various sizes of Bulk carriers and Oil tankers. It verified that impacts of variables other than ship size and age were significantly associated with ship type and size while macroeconomic variables had no influence except for bulk carriers. By applying diverse variables affecting secondhand ship price estimation according to various sizes of Bulk carriers and Oil tankers, this study will expand the scope of practical application for investors. It also reaffirms prior research findings that the secondhand ship market is primarily market-driven.

  • The purpose of this study is to find out the impacts of VTS on the marine safety and users' opinion on the VTS which have been being operated in the port of Pohang for the last 3 years and is to suggest a guideline to the successful operation of VTS in the future. This study is based upon the questionnaire survey and the respondents include 236 masters/mates of merchant vessels who have visited the port of Pohang and 6 pilots who have been working in the port. From the questionnaire results, this study notes the following conclusions related to the VTS operations. (1) A few of the respondents (mainly foreigners) do not understand the entering procedure of the port and the fundamental concept of VTS. Accordingly, the more active VTS services have to be provided for the mariners. (2) It was found that themost dangerous factors in tehvicinity of the port were the floating materials, fishing nets, andillegal fishing activities inthe fairway. Therefore, the proper surveillance, stricter enforcement of Acts and the instructive education for the fishermen are required to avoid the risks. (3) A majority of the respondents agreed the VTS has contributed to the safety of vessel traffic, and they pointed out ' the assiatances in reduced visibililty conditions' is the most important task of VTS. The amount of 75.6% of the respondents answered that they have experienced the assistance from VTS more than 1 time since the system was established in the port of Pohang . Also 44.2% of the respondents considered they were able to avoid marine casualties such as collision, ramming or agrounding with the VTS assistances. (4) 49.2% of the respondents preferred the passive information services , while, 38.8% of them preferred the positive control advices in the case of encountering any potential risks. VTS iperators have to consider seriously when they provide the positive control advices of ship's course and speed. (5) A majority of the respondents confirmed that the prot and its approaches is suitable for the VTS coverge . To extend the service areas of the VTS and to improve radar detecting ability, the use of radar transponders are seen as the ideal method. (6) A minority of the respondents pointed out 'the improper orders or recommendatinos caused by the poor decision making' firstly, ' the language problem(sea-speaking in English)' secondly, as the deficiency of personal qualification. It seems, therefore, theat the personal efforts of the operators and systematic training programmes for them are necessary to solve the problems.

  • The short-term impact of the recent depreciation of Korean Won on the cost of the Korean logistics industry, which was caused by the global liquidity crisis began from the American financial market in 2007, is analyzed through the inter-industry analysis. The input-output data of the 2007 benchmark input-output accounts table which was most recently published by the Bank of Korea in 2009 have been utilized for the analysis. The results show that the cost of the Korean logistics industry as a whole rises 4.24% when the Korean exchange rate is depreciated by 10%. The impact of the depreciation of Korean exchange rate on the cost of the Korean logistics industry for December, 2007 ~ December, 2008 is estimated to be about 31.1 billion Won. If the Korean logistics companies should cover the rising cost of 11.7 billion Won only through sales promotion, then they should sell 1.9 times as much their current sales amount, which means 101.6 billion Won's worth of sales should be made.

  • The purposes of this study were to identify the economic impacts of hosting a marine leisure event and thus provide fundamental information that helps maximize the economic value of the event. In order to accomplish such purposes, this study employed both an economic impact analysis(EIA) using regional input output model and a benefit and cost ratio analysis(BCR). In specific, this study utilized a survey method with a total of 300 event visitors and 70 foreign players and thus collected expenditure data from 110 valid out of town visitors and 58 foreign players. In addition, investment expenditure data were collected from the host city official. Accordingly, EIA and BCR indicated following findings. First, the total direct impact from both visitors and players was 387 million Won and this direct impact resulted in output multiplier effect(OME) of 591 million Won, value added multiplier effect(VAME) of 306 million Won and income multiplier effect(IME) of 252 million Won. Second, the host city's investment expenditure created OME, VAME and IME of 825, 432 and 366 million Won, respectively. In conclusion, these findings suggest that in order to effectively boost potential economic benefits, more marketing efforts development policies should be implemented for increasing the number of out of town visitors and the amount of spendings from them.

  • In the United States, a number of ocean outfalls discharge primary treated effluent into deep sea water and contribute for more efficient wastewater treatment. The long multiport diffuser connected by long pipe from a treatment plant discharge wastewater into deep water due to the steep slope of the sea bed. However, Plume discharged from the diffuser can have significant impacts on coastal communities and possibly immediate consequence on public health. Therefore, there have been growing interests about the dynamics of plume in the vicinity of the ocean outfalls. It is expected that the ocean outfall should be considered for more efficient and reliable wastewater treatments as soon as possible around coastal area in South Korea. A number of studies of plume ynamics have used various models to predict plume behavior. However, in many cases, the calculated values of plume behavior are in significantly poor agreement with realistic values. Therefore, in this study, it is recommended that improvements should be made in the application of the plume model to more simulate the actual discharge characteristics and ocean conditions. It should be noted that input parameters in plume models reflect realistic ocean conditions like waves as well as currents. In this study, as one of the new parameters, current and long wave-influenced plume rise and initial dilution have been taken into account by using simple linear wave theory under some specific assumptions for more reliable plume behavior description. Among the improved plume models approved by EPA (Environmental Protection Agency), the RSB(Roberts-Snyder-Baurngartner) and UM(Updated Merge) models were chosen for the calculation of plume behavior, and the variation calculated by both models on the basis of long period wave was compared in terms of plume rise and initial dilution.

  • Our society has been changed so rapidly and we have achieved industrialization and democratization swiftly. On our Economic growth and democratization, it is appraised that Christian Thought and western Capitalism thoughts have been one of the important factors. John Calvin, well known Reformer and thinker of Protestant, as M. Weber assessed, contributed greatly to the progress of Capitalism. He was a Religion Reformer as M. Luther and especially a thinker and man of deed, who affected large areas of human life such as Religion, Economy, Society and Politics. Calvin understood Economy is the main issue of theology and Economic activities can be a position which may restore the correct relationship of God and Man. This Paper aimed to survey, synthesize and systemize the Economy and Management thought of J. Calvin. On these changing current society, it surveyed if His thoughts that has long history, can be applicable or not and Where and How it may. Calvin's Thought not only on his age caused important changes and Reformation but now suggests critical milestones. His Thoughts of Love, Justice, and Fairness based on the Bible have been evaluated as the universal truth and important criteria. Until nowadays his Philosophy has composed critical Principles of decision making rules of Economy and Management and National policies. Especially today, when economy has been more emphasized as a center of our lives, His Thought suggests momentous directions on various Human Life such as Justice and Fairness, deepening of gap between poor and rich, expansion of conflicts among social classes, employment and wages, freedom of markets and its balance, and public good of land use. Reviewing Calvin's Economy and Management thoughts as meaningful basis on the our and world Economy which became worse caused by world monetary crisis and Europe financial crisis that aroused by world Economy globalization and expansion of neo-liberalism, this Paper suggested some future directions. And for the practical sectors, Distribution and Logistics, it proposed some issues and Directions, considering the impacts of His thoughts on the Industries. Nevertheless it can deliver some contributions, as a literature research, it reveals some limitations that it may contain lacking of practical investigations and cases on economy and management fields. In the future, more detailed and deeper research on the practical and situations of economy and management shall be needed.

  • In general, spatial imbalance in regional growth is a major cause of social and political conflicts within a state. In Korea, this inequality has functioned as a threat to the state's integration. With the economic development policies by regional industrialization over the past three decades, most of the industrial activities have been concentrated in Seoul and Pusan metropolitan areas, which are surrounded by Kyonggi, Kyongnam provinces respectively. Compared to these areas, Chonnam and Chonbuk provinces have lagged behind in economic development. Therefore, in order to increase the regional economic development of the southwestern region in Korea, the central government has been enforcing several policies aimed at regional industrialization since the 1980s. The purpose of this study focuses on the regional economic impacts of a newly established industrial estate-Yulchon industrial complex- which would act as a regional growth center in the Kwangyang bay area. The Kwangyang bay area consists of several industrial estates such as Kwangyang Iron and Steel Co. and its related industrial complex, Chuam rural industrial estate, Yeochon industrial complex, and so on. In addition, the Kwangyang container port was constructed in 1997. The Kwangyang bay area has been changing to a new industrial district in the southwestern part of Korea as a result of industrialization policies which were activated by central government. The Yulchon industrial complex, which is expected to be completed in 2001, would draw many manufacturing plants. For example, Hyundai Motors Co. has a plan to locate a new automobile assembly plant within the estate. As the plan has high probability to be realized, it will be interesting to study the effects a new automobile assembly plant and its related production linkages have on the region. This study is to estimate the expected structural characteristics of automobile production activities in Yulchon. The following details will be discussed: the regional economic impacts of a new automobile industry in Yulchon industrial complex, the production linkage formation via hierarchical subcontracting systems, the alternative strategies to promote the growth of regional economies, and the scheme to improve the auto-parts and components industry in Kwangju and Chonnam provinces by establishing auto-mobile production function. Automoblie industry generally gives great influences on not only regional economies but the related industries, for example, the firms producing automotive components. If a new plant producing automobiles and its related firms producing components are to be established in Yulchon, they will affect on the regional development directions and change the regional characteristics of industrial structure. In order to increase the spread effects of the new industry in Yulchon industrial complex, almost all of the automobile production processes must be organized concurrently within a limited range of distance. There is an imperative that the co-operation system should be structured between the assembly firm and many firms producing its components. In addition to those, it would be required such as the effective division of labors between the firms, much more capabilities in the technical innovations, and the reconstruction of interrelationship between the labor unions and the firms' managers.
