A Study on Recent Credit Loan from Households in South Korea
Jeong,Dong-Bin 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
In this paper, we examine a causal relationship between a response variable credit loan from households and several explanatory variables such as interest of certificate of deposit (CD) and loan collateralized with housing and so on. Based on 31 observations sampled from the 4th quarter in 2008 to the 4th quarter in 2016, the optimal forecasts can be obtained and expected to apply to the distribution area comprehensively. In order to accomplish the objectives, both the multiple regression model with correlated errors and several exponential smoothing methods are, in main, analyzed by using IBM SPSS 23.0. A number of goodness-of-fit statistics, at the same time, are also exploited as a tool of optimal model-building.
A Review on Sales on Large-scale Retailing Types in South Korea
Jeong,Dong-Bin 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
In this work, we investigate several time series models to forecast of sales at department stores and at discount stores in South Korea. Considering two large-scale retailing types are homogeneous and comparable in size based on 86 realizations taken from January in 2010 to February in 2017. The dataset of this work is got from Korean Statistical Information Service (KOSIS) and Survey of Service Trend of Korea Statistical Administration, and we exploit the procedures of IBM SPSS 23.0 such as TSPLOT, TSMODEL, EXSMOOTH, ARIMA and MODELFIT. Several model-fit measures, simultaneously, are also used as criteria of the optimal model construction. Time series models can not only predict future sales but can account for economic or business mechanism and increase our understanding of relationships among phenomena or variables under consideration.

The average indoor concentration of the library's TSP was 0.03 ng/m³. TAB in library and lounge in college of engineering showed higher concentrations in corridors than indoors. The correlation coefficient between TAB and humidity is 0.985, so it is judged that there is a significant need for humidity control in indoor air quality management to reduce the concentration of total suspended bacteria(p<0.01).

현재 본격적으로 진행중인 WTO DDA 농업협상이 타결된 후에 세계 농산물 교역질서는 보다 더 비교우위에 입각한 경쟁체제로 돌입할 것이다. 특히, 이번 협상은 국내보조 및 수출보조의 감축과 시장개방의 대폭적 확대를 목표로 이루어지고 있으므로 향후 협상 타결의 결과로 국내농업에 미치는 부정적인 파급효과는 지난 UR협상 타결로 발생한 것 보다 훨씬 더 클 것으로 보인다. 이에 본 논문은 WTO DDA 농업현상이 분야별 협상골격(Modality)마련에 돌입한 현 시점에서 주요 협상 쟁점을 살펴보고, 향후 WTO를 중심으로 전개될 다자간 협상과 세계농산물 교역질서 변화에 효과적으로 대응하기 위한 정책적 대응방안을 제시하고자 한다. The Korean agricultute seems to experience the greater negative impact after the settlement of WTO New Round rather than UR Agreement on Agriculture. It is because that the ongoing negotiations on agriculture will likely result in further reductions of export subsidies and trade-distorting domestic subsidies, as well as reduction of tariffs and expansion of the market access. Therefore it's time for us to prepare the policy measures coping with the change in situation in order to minimize the negative impacts on agricultural sector. The main purpose of the study is to summarize and illustrate some of the major issues in the current WTO negotiation on agriculture. Also the paper presents some policy implications and missions so as to minimize the negative impacts of agricutural trade liberalization on the Korean agriculture.

Extraction yields of Zunthoxylum piperiturn by organic solvents and supercritical carbon dioxide(SC-CO_(2)) with and without ethanol as a cosolvent, and antimicrobial activities of the extracts against Hucillus cereus were determined. Extraction yield by distilled water was the highest, 20%, while those by ethanol, ethyl ether and hexane were less than 3%. Extraction yield by SC-CO_(2) Lvith ethanol was 1.42 times greater than that by only SC-CO_(2). Ethyl ether- and ethanol-extracts had potent antimicrobial activities against B. cereus. Extraction yield by SC-CO_(2) with ethanol showed almost the same degree of microbial growth inhibition as that by only SC-CO_(2).

In extremely non-symmetric distribution it is very difficult to design the sampling method. Cut-off sampling is a proper method in this situation. In this method it is not easy to decide the cut-off point which devide two strata. A criterion of deciding the cut-off point which devide two strata will be suggested by using population-ratio of a specific item, sampling number and MSE.

The purpose of this study was to investigate how cards affects on household economy. The data were collected from 239 housewives in Seoul. Multiple regression and path analysis were used as statistical analysis. The major findings were as follows: (1) The less income, the more number of credit card, the less optimistic on the financial expection in the future, the higher the use purpose of "circulating money". (2) The less income, the more number of credit cards, the higher education level, the more optimistic on the financial expection in the future, the more the use amounts of credit card. (3) The lower age, the more income, the less number of credit cards, the more the use amounts of credit, the more monthly savings. (4) As a result of path analysis, while the number of credit cards positively affected on the use purpose and the use amounts of credit card, those negatively affected on monthly savings.

The purpose of this study is to prepare and present a method for managing and manipulating skyline in Suwon city, from the view point of historical landscape preservation. In this study, the historical landscape is defined as the urban landscape which has the elements of historical spaces, and the high-rise building is defined as a building of eight or more stories. Sixteen key view points, through the field survey, are selected from sixty five candidate view points. Based on field survey and key views, sensitivity map has been drawn. The key view points, key views, and sensitivity map are the devices for the management of urban skyline. Because the view to the historical landscapes is a very important component of urban landscape management, it is necessary to provide systematic and effective ways of controlling urban skyline. Further more, landscape impact evaluation system needs to be adopted as a part of high-rise building permission process.
