  • In 2009 the Korea Ministry of Environment announced 'A Comprehensive Plan for the Improvement of Sewer Service in Rural Area' aiming at reduction of the sewer service gap between urban and rural areas as well as improvement in the residential environment of the rural area. According to the plan, the sewer system supply rate for the rural area is expected to reach up to 75% until 2015 with the budget of 4.7 trillion won (Korean currency). It is not certain, however, that the increase in the sewer system supply rate will accompany improvement of water quality in receiving water because several veiled problems that can occur in small-scale sewer treatment plants are poorly addressed in the plan. In this study, those issues for the small-scale sewer treatment plants and their solutions were discussed based on a case study in which we investigated 19 treatment facilities at two rural regions in Gyeonggi province. This study also included strategies useful for the plan. From the results of investigation, some problems, e.g., high hourly variations but low in flowrates and low mass loading were commonly identified. Although operation parameters in sewer treatment plants require to be modified depending on the mass loading, most of the plants were operated with the initial design parameters which causes the decrease of removal efficiency. In the intensive diagnosis, we arranged and applied solutions (e.g., flow equalization, air on/off time control, etc) to the two selected plants and found out improvement of effluent water quality, especially organic matters (COD and SS) and T-N with better denitrification performance.

A Study on the Duty of the Business Owner in the Contents(Casino) Corporation related with the Commercial Law - In the case of claim for damages of the gambler against the Kangwon Land(Supreme Ct. 2014.8.21, 2010다92438 case) (상법상 유기장콘텐츠 영업주(카지노영업주)의 주의의무에 관한 연구 -강원랜드 카지노 이용자의 손해배상청구의 경우 (대판 2014.8.21., 2010다92438 전원합의체 판결))

  • This is Kangwon Land casino case due to the damages of betting money, which is likely to affect the contents industry in the future. The reason why the gambler and his family's suit is that why the manager did not control their own access or did not supervise the wagering rules. The provisions of the "Restriction on the amount of money to be paid to the casino" in the Article 14 of the Enforcement Decree of the Act on the Support for the Development of the Abandoned Mine Area are not intended to increase the duty of the casino managers. It is just one of many public regulations imposed. No matter what legislation is made for public interest, it can not be considered equally in the private duty. If so, too much effort will be required to enact or amend the public law and this makes the legislative activity impossible. The Act on the Restriction on Access to the Casino shall be construed accordingly. From the point of view of economic efficiency theory, if we overestimate statutory duties (liability for compensation) excessively, the price goes up on the market, and the volume of transaction decreases drastically. This reduces the economic utility of resources in the society as a whole (total output, foreign currency acquisition amount, etc.).

  • Purpose - This work analyzes, in detail, the specification of vector error correction model (VECM) and thus examines the relationships and impact among seven economic variables for USA - balance on current account (BCA), index of stock (STOCK), gross domestic product (GDP), housing price indices (HOUSING), a measure of the money supply that includes total currency as well as large time deposits, institutional money market funds, short-term repurchase agreements and other larger liquid assets (M3), real rate of interest (IR_REAL) and household credits (LOAN). In particular, we search for the main explanatory variables that have an effect on stock and real estate market, respectively and investigate the causal and dynamic associations between them. Research design, data, and methodology - We perform the time series vector error correction model to infer the dynamic relationships among seven variables above. This work employs the conventional augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root techniques to test for stationarity among seven variables under consideration, and Johansen cointegration test to specify the order or the number of cointegration relationship. Granger causality test is exploited to inspect for causal relationship and, at the same time, impulse response function and variance decomposition analysis are checked for both short-run and long-run association among the seven variables by EViews 9.0. The underlying model was analyzed by using 108 realizations from Q1 1990 to Q4 2016 for USA. Results - The results show that all the seven variables for USA have one unit root and they are cointegrated with at most five and three cointegrating equation for USA. The vector error correction model expresses a long-run relationship among variables. Both IR_REAL and M3 may influence real estate market, and GDP does stock market in USA. On the other hand, GDP, IR_REAL, M3, STOCK and LOAN may be considered as causal factors to affect real estate market. Conclusions - The findings indicate that both stock market and real estate market can be modelled as vector error correction specification for USA. In addition, we can detect causal relationships among variables and compare dynamic differences between countries in terms of stock market and real estate market.

  • The aim of this study is to empirically explore micro and macroeconomic factors affecting the Pakistani sugar industries and searching the energy potential of this industry, through the survey of literature. The empirical part has been explored by employing Vector Autoregression (VAR), Granger Causality tests and simultaneous equation models through quarterly data for the period of 1991q2-2008q4. The study also aims to devise policies for the development of sugar industries and identify its growing importance for the energy sector of Pakistan. Empirical tests applied on the domestic prices of sugar, domestic interest rates, and exchange rate, productive capacities of sugar mills, per capita income, world sugar prices on cultivable area and sugar production reveal very useful results. Results reveal an improvement of productive capacity of the sugar mills of Pakistan on account of increasing crushing capacity of this sector. Negative effect of rising wholesale prices on the harvesting area was also observed. Profit earnings of the sugar mills significantly increase with the rise of sugar prices but the system does not exist for the farming community to share the rising prices of sugar. The models indicate positive and significant effect of local prices of sugar on its volume of import. Another of the findings of this study positively relates the local sugar markets with the international prices of sugar. Additionally, the causality tests results reveal exchange rate, harvesting area and overall output of sugarcane to have significant effects on the local prices of sugar. Similarly, import of sugar, interest rate, per capita consumption of sugar, per capita national income and the international prices of sugar also significantly affect currency exchange rate of Pakistani rupee in terms of US$. The study also finds sugar as an essential and basic necessity of the Pakistani consumers. That is why there are no significant income and price effects on the per capita consumption of sugar in Pakistan. All the empirical methods reiterate the relationship of variables. Economic policy makers are recommended to improve governance and management in the production, stock taking, internal and external trading and distribution of sugar in Pakistan using bumper crop policies. Macroeconomic variables such as interest rate, exchange rate per capita income and consumption are closely connected with the production and distribution of sugar in Pakistan. The cartelized role of the sugar industries should also be examined by further studies. There is need to further explore sugar sector of Pakistan with the perspective of energy generation through this sector; cartelized sugar markets in Pakistan and many more other dimensions of this sector. Exact appraisal of sugar industries for energy generation can be done appropriately by the experts from applied sciences.

  • Purpose - The purpose of this study was to clarify the factors to make an exclusive importation contract between foreign fashion brands and local retailers for successful business in Korea. Even though imported fashion brand market shows stead increasing in terms of sales amount, the number of store related study was very rare in fact. Meanwhile, as long as this business is glowing a lot of brands are suffering from bad business performance or getting in ruins thus these problems result in foreign currency loss. The local marketers therefore, strongly expect to know the solution for this matter. Research design, data, and methodology - For the qualitative research, 10 experts who are operating foreign brands with an exclusive contract at a department store or at duty free shop now and who had at least over 10 years of related working experience were included. The factors for the exclusive importation contract with foreign brands were drawn up through the one-to-one in-depth interview method from September 3, 2017 to January 15, 2018. The expert group for the validity analysis includes 2 professors and 5 postgraduate students. Results - As a result of qualitative study on the factors for imported fashion brand's launching with the exclusive importation contract, it turned out that there were 5 factors - safety, profitability, reliability, speed and global retailing. Safety, profitability, and reliability have been mentioned in most related surveys but some details are added and speed and global retailing have been newly highlighted and many unknown legal issues that it was not easy to get form common academic research are included. Speed simply means quick lead time and global retailing means stores where located in other countries. Conclusions - The reason that qualitative research should be done before the quantitative research is due to the scant theoretical background for this matter. Because the market of an imported fashion brand is steadily increasing, determining the factors to make exclusive importation contract is very meaningful from the point of academic and business. After this study, many marketers may get basic conditions to apply for real business and I hope the following quantitative research will give more effective results. The next study also will have extended range concerning industry area, product and distribution channel.

  • The purpose of this study were to :(a) investigate meal costs, plate waste costs, and advantages/disadvantages of conventional /commissary foodservices and (b) compare the effectiveness of commissary foodservice systems with that of conventional systems. Questionnaires were developed and mailed to 136 schools in Kyonggi-do. A total of 106 questionnaires were usable, resulting in a 77.9% response rate. Teacher's teaching of good food habits and students satisfaction with school foodservices were surveyed in three schools from each system. Moreover, plate waste was measured to express cost and benefit in currency. Data were analyzed using the SAS package for description analysis, t-test, $\chi$$^2$ test, ANOVA, and the Vilcoxon rank sum test. Approximately seventy percent of 294schools in Kyonggi-do were operating commissary systems and most of them were of the rural (reduced paid) type. The number of meals served varied significantly between types of foodservice. The results of this study indicated that average food , labor utility , and supply costs were saved in the commissary system and that the total meal cost/person for a day was 1218.7 won compared to 1452.4 won in the conventional system. Though total meal costs were saved in the commissary system, dietitians had difficulties cooperating with school foodservice committees and supporters associations, especially in satellites of the commissary system. In addition, dietitians and teachers in the commissary system did not carry out teaching activities on good food habits to students as often as in the conventional system. Other problems that dietitians recognized in the commissary system were difficulties in training employees and parents for portion control and serving relatively simple menus. Students, as customers of school foodservices, are very important for system evaluation . Students in the commissary system scored of food itself , cleanliness of tableware, waiting time, quantity of meal and food temperature significantly lower than students in the conventional system. Moreover , the rate of plate waste was 20.5% in the commissary system as compared to 3.3% in the conventional system. Cost-effectiveness (saving 233.7won/person/day) is the main benefit of the commissary system. However , because of lower satisfaction scores and a highest plate waste rate, 201.9won/ person were wasted in the commissary system. The results of this study suggest that increasing the number of meals served within a commissary system might maximize the efficiency of the system, but increasing the number of satellites is not recommended because it might be out of dietitians control in many aspects.

  • Korean society, suffered from a severe currency crisis in 1997, had scarcely missed another market meltdown in 2008. However, neither economic fundamentals nor has political stability little to do with the recent crises. This paper thus projects the possibility of 'self-fulfilling crisis' in which the media took a critical part in amplifying 'crisis discourses.' For the purpose of understanding of media's impact on such a crisis, at first, this paper chose 'September Crisis in 2008' as a case study. While collecting news articles about the crisis, then, total 118 news articles collected from mainstream newspapers such as DongA-ilbo and Money Today have been analyzed in terms of media frame and discourse strategies. Research results showed that not only has the crisis discourse been shifted by economic situations, but the media re-constructed economic realities in way of justifying their political ideology and loyal readership. Taking those findings into consideration, in final, the authors urged the media to improve their performance by embracing more responsible and professional manners.

  • There emerges a growing concern about South Korea's intellectual dependence on U.S. financial news media. However, those media's inherent relationship with national economic and financial interests has been poorly addressed. This paper thus attempts to identify such a strategic partnership between media and the government by analysing news coverages over four critical arena interwoven with U.S. dollar based financial system. For this purpose, total 152 news articles about Asia crisis, Asian Monetary Fund, Malaysia currency crisis and the new international financial architecture have been examined in terms of frame, attitude, cue-givers and discursive strategies. Research results indicate that not only have the media actively deferred to government leadership bur they have also acted as public diplomats in way of not hampering journalistic credibility. Hence, it is claimed that Korean society needs to formulate a model of media's strategic partnership with government at least in foreign policy arena, as well as to launch discursive strategies against nation-bound global news media.

  • Due to development of science and telecommunication with wide-spread computer supply, it could be done through computer automatically instead of manpower-work for paper transportation & paper approval. It is developed to so-called Factory Automation. Further, it is developed to Office Automation. Trading companies & concerned trade authorities are interested in Trade Automation that such technique is applied to trade work. Generally, Trade Automation means to realize paperless trade by exchanging electronic papers through inter-computers after concerned trade operators transformed various papers to electronic papers that computer could read. In case Trade Automation fix in the trade business, it is expected one of innovations among traditional paper work of trade business, namely without going import-export authorities, Customs office, Banks. Shipping companies, Marine insurance companies on hand-carrying papers, it could be fast, simple, correct to finish every trade procedures such as commercial business, foreign currency, customs clearance, transportations, insurance. terms of payment, etc., with Electronic Data Interchange through computer facilities. Especially, telecommunication for trade form could be helpful to proceed trade paper with one-run-method Further we can anticipate 6 effects for Trade Automation as belows : First, as explained just above articles, with completion for Trade Automation, every trade procedures can be done by computer. so, time to work can be diminished. namely. logistics cost including accessory costs for trade procedures can be saved much. Second, viewing to private enterprise, effect of Office Automation can be maximized and rapid, correct exchange for various trade informations could raise efficiency of enterprise management establishing rational production, storage, transportation and could raise competition improving standard for consumers's service. Third, establishing Trade Automation systems makes it easier piling-up of harbor cargo by pre-transmission of electronic paper & trade informations make it possible to finish customs clearance in advance and can be dispatched upon cargo arrival. Fourth, most of concerned trade authorities such as import-export approval office. financial authorities, transport & insurance companies concentrated in Metropolitan area(Seoul, In -Cheon, Kyung-Ki).

  • the present thesis aims to contribute to the further development of the men's wear indus-try in Korea which now confronts the need to adjust itself more actively to the conditions of the coming age of internationalization and free trade. To achieve this this thesis suggests the trade should provide for the changing domestic needs on theone hand and refine its wares as high value-added products in compe-tition with those from the advanced countries in fashion industry on the other, The history of the 'suit' the standard men's attire dates back to 1850 when the 'Ditto suit' was introduced composed of coat waist coat vest and trousers to remain virtually unchanged till the end of the nineteenth cen-tury and the modern men's wear originated in Britain. In Korea since the introduction of western clothes from 1876 custom-made suits had been dominant until 1944 while western clothes earned popular currency between 1945 and 1964 and ready-made suits began to spread with their advantages recognized in terms of practicality convenience and functionality The next phase from 1965 to 1985 witnessed the establishment of a number of ready-made brands although custom-made suits stayed in their height of prosperity until 1975. The turn-ing point for the men's wear industry came in 1975 when high-calss ready-made brands be-gan to turn up with the arrival of large companies in the market matching the change in consumers' life style. The men's wear market went through further diversification and specialization dur-ing the years between 1985. and 1990. Around the year 1990 however the expansion of the business suit industry came to slow down ac-companied by an oversupplied market. The fashion of pragmatism in the 1990s called for the growth of the casual wear department and as consumers' life style became more and more individualized conscious dressing in accord ance with T.P.O established itself as an important branch of culture, Such casual boom is likely to aid in promoting Korea's men's wear indus-try to peer with that of advanced countries. Consumers' fashion sense is now ahead of the trade's as well as being shortcycled highly individualized stylized and diversified. To meet consumers' demands under such circum-stances each company is required to develop its unique soft Know How based on accurate information and strategically specialized plan-ning. The trade should convert its hithero producer-oriented strategy to a new consumer oriented one and actively lead the needs and purchasin g pattern of consumers by providing an efficient and reasonable price policy with optimum supply of merchandise and also by presenting 'our' trend suited to our circum-stances.
