This study proposes and verifies an integrated model that reflects and helps to explain complexities and comprehensiveness of e-Trade in practice. The primary objective was to widen and deepen our understanding about the phenomena of paperless trading which will enable us to formulate an effective means to promote the adoption and utilization of e-Trade infrastructure. This investigation combined and extended the theories and models of TAM, TOE framework, and TTF in order to identify and hypothesize the causal relationships between factors of technology, organization and environment, and the usage level and performance of e-Trade. The previous research on e-Trade was reviewed and incorporated into the extended model. The integrated model was tested based on the survey data collected from a sample of 417 trading firms. Overall, the regression and path analysis demonstrated the usefulness of the proposed model as a conceptual framework for better understanding and explanation of e-Trade. The result of the analysis implies the relevancy of the factors of technology, organization and environment for facilitating usage of and increasing performance of e-Trade. However, rejection of a few hypothesized relationships implies the necessity of extensive promotion and education about the related laws and regulations, and education, supervision and incentives for e-Trade practitioners.

Seoul is an ancient city with a long history but there is hesitancy over referring to as a historic city due to the lack of traceable historic urban landscape elements which resulted from numerous invasions and general destruction. From a diachronic perspective, the nature which was survived the influence of development, could be the key element that links the past with the city's radically changed image in modern times. Although "old big trees" may be not a dominant influence with regards to the historical authenticity of the city, they are objects which contribute towards the historical authenticity by providing a sense of place in terms of connected narratives, as well as their natural image. However, the protection policy for an "old big tree" would place too much emphasis on the aspect of the ecological value rather than its cultural value. Generally, trees have been protected by installing a fence and a signboard around them as well as receiving additional care. However, it is difficult to find that surrounding space around the "law-protected tree" is connected with its original historical and cultural values. Even though the space around trees are no longer utilized in the same way as was so in the past, they still have high-potential in terms of cultural utilization. Therefore, the subject of this study is the "old big tree" as a natural object which contributed to the historical authenticity of Seoul. The current status of these "old big trees", aged between 100 and 800 years old, currently indicate that there are 215 trees designated as "law-protected tree" by the Seoul metropolitan government. This study aims to investigate the status of protection and utilization of the existing "law-protected trees" in the city of Seoul and find a way to increase both ecological preservation and cultural utilization for the high-potential "law-protected trees" within the city itself. In order to achieve this, previously researched papers shall be reviewed and surveyed pertaining to present usage patterns of the 215 "law-protected trees". In addition, five cases have been reviewed which focus on a few of utilizing the "protected trees" and their surrounding spaces. The results of the research indicate that 21 "old big trees" have high-potential in terms of cultural utilization as well as ecological value. However, it was revealed that there are limitations to pursue the value of preservation and utilization simultaneously throughout current regimental management. In order to cope with the current situation, it is pointed out that management facilities should be designed and installed by creative and flexible methods of organizing with consideration to the surrounding space and context. Even though in the case where there may not be a connecting history or legendary stories, the "old big trees" can serve as the fundamental features of small scale parks -dependent on their location, condition and environment- which will be of value to the local communities. This study could serve as a practical reference for the management and utilization of "old big trees" nationwide with numbers reaching 12,300 besides the city of Seoul.

Centrifugal fans are widely used and the noise generated by the these machines causes one of the most serious problems. In general, the centrifugal fan noise is often dominated by tones at BPF(blade passage frequency) and its higher harmonics. This is a consequence of the strong interaction between the flow discharged form the impeller and the cutoff in the casing. However, only a few researches have been carried out on predicting the noise because of the difficulty in obtaining detailed information about the flow field and casing effects on noise radiation. The objective of this study is to understand the generation mechanism of sound and to develop a prediction method for the unsteady flow field and the acoustic pressure field of a centrifugal fan. We assume that the impeller rotates with a constant angular velocity and the flow field of the impeller is incompressible and inviscid. So, a discrete vortex method (DVM) is used to model the centrifugal by the unsteady Bernoulli equation. Lowson's method is used to predict the acoustic source. A centrifugal impeller and wedge introduced by Weidemann are used in the numerical calculation and the results are compared with the experimental data. Reasonable results are obtained not only for the peak frequencies but also for the amplitudes of the tonal sound.

The purpose of this study was to analyze spatial composition of elderly skilled nursing facility and to provide basic information for setting up the detail facility architectural guidelines. The results of the study were following: the residential spaces of the facilities in this study were more or less overcrowded since their capacity were more than 5 elderly residents. The dimensions of some residential spaces did not even come up to the standard of elderly welfare law in force. On the other hand, the facilities had a tendency to use a space with multiple purposes or to allocate a space but to leave it with no use. Moreover comparing with the 1st floor, which was mainly for the staffs and had enough space to spare, the upper floor which was for the elderly residents, was crowded with nursing staffs and elderly residents and had densely closed residential and public spaces. For the problem solving, law and regulation modification is needed according to the case study about the usage and using frequency of each facility space. And the crowded area for the elderly residents could be enlarged through the reduction(or combination) of the rarely used spaces and moving a few residential spaces into the 1st floor.

A rapid increase in traffic accidents involving senior vehicle occupants has been an issue in Korea because of the aging of the population occurring at one of the fastest rates in the world; unfortunately, few studies beyond several looking at the effect of senior occupants on the level of accident injury severity can be found in the literature. A Multinomial logit model was estimated with Newton-Raphson algorithm to perform bias-reducing penalized likelihood optimization. Model covariates integral to developing the model were included, but the main focus was on the interaction of seating position and injury to senior vehicle occupants. It was found that the likelihood of an accident resulting in a fatality increased: 2.2 times for the driver seat, 2.7 times for the front passenger seat, and even 6.7 times for the rear seat. A mandatory seatbelt law to be extended to the rear seat needs to pass the assembly as soon as possible, and government, industry, and safety groups should be encouraged to join forces to strongly carry out targeted campaigns for the wearing of seatbelts in all vehicle seats to enhance the safety of senior occupants as well as other occupants who are vulnerable to road traffic accidents.

East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

The Korea health care system has been divided into Western and Oriental (Korea traditional) medicine since 1951. In accordance with dualistic medical system, there are many conflict cases between medical doctors and oriental medical doctors. Meanwhile, there were much discussions about the meaning and criteria of medical malpractice(negligence). Especially, many cases have been built up about the criteria of medical malpractice through lawsuits. But, comparatively, there's few the medical malpractice case of the oriental medical doctors. According to a recent ruling of the Supreme Court, the legal principles of medical doctor's malpractice case are equally applied to the criteria of the oriental medical doctor's malpractice case. But there are much considerations in addition to these principles for the dualistic medical system and academic distinctiveness. This study is intended to review the dualistic medical system, the criterion of medical malpractice, and analysis this issues. To make long story short, under our dualistic medical system, judging the medical and oriental malpractice should be considered relatively. However, it makes sense that we want medical doctor or oriental medical doctor to demand the reinforced negligence to restrict the unnecessary discretion. If there is lack of evidence-based medicine or the rationality suspected, the health care providers must give enough proof.

This study was carried out to investigate the view of the choice of spouse and marriage of unmarried women's college students. Most respondents in this study think that the optimum age for marriage is 27 and prefer a seniority in age of 3-4 years who feels in love as the future husband. Also, they wish that the job of future husband be a technical expert. Approximately 63% of respondents recognize the necessity of marriage but 38% of respondents do not show a positive opinion for marriage. They also expect the emotional stabilization or partnership from marriage. Majority of respondents show a negative response to the marriage as means to solve economic difficulties. However, only 25.9% of respondents strongly show the negative opinion. In the acquaintance of the opposite sex in the purpose for marriage, most respondent are negative. However, they are positive in keeping virginal purity prior to marriage. Also, it has revealed that respondents want a partnership through allotment in domestic duties including baby sitting rather than household management through patriarchal system. In household economy, they prefer sharing living expenses and having a job after marriage. In choosing an ideal husband, although the academic background is considered as an important factor, but the present occupation is more important than the academic background. Also, one of the priority to choosing a spouse is influenced by each household circumstance and economic balance. About half of respondents want their parents-in-law to be alive, however, few respondents want to live together with parents-in-law.

The documentary credit has been functioning as an indispensable tool for making international commercial transactions safer throughout the world since ICC adopted the second revision of the Uniform Customs and Practices for Commercial Documentary Credits in 1962. Letter of Credit transaction should be cleared by the principle of the trust and integrity and vile partners sometimes make a fraud on the L/C by the misinterpretation of the documents. As there is no rule but no exception, exception from application of these principles is allowed. The fraud exception nile constitutes contracting out an application of basic principles, this rule should apply restrictively and in many authorities a court does not apply this rule to nominated bank, confirming bank, and bona fide holder of draft even if fraud is involved in L/C transactions. If not, we lose a lot of benefits from the credit as valuable commercial device through reservation of these principles to take a few benefits. So, We need to recognize that the fraud exception rule should be applied restrictively. Therefore, this study reviewed condition of application and exception from application of fraud exception rule in view of Cardozo's opinion, the Sztejn court, and UCC Sections-114(2).

Considering above, It might be efficient that medical disputes would be settled by the intervention, the agreement, and the administrative relief that reflect mediators' opinion, who have rich social experience as well as specialized knowledge. Therefore, KCA needs to strengthen its function of mediation and improve relevant systems to become an effective settlement institution. And although Oriental medicine disputes have mainly given ex post facto explanations so far, administrative efforts such as policy development or legislation should be made for the high quality of Oriental medical services offered because an efficient way saving social or economic costs caused by the dispute would be precautionary measures. The traditional Oriental medicine is featured with the lack of baseline examination, the uncertainty of medical mistakes, the difficulty in clarifying and proving facts, the hardship of injury conformation and causality because of the characteristics of Oriental medicine, and the relative lightness of physical damages. Actually, there has been few legal settlements in Oriental medical disputes since the compensation, itself, compared to the lawsuit cost, is relatively much lower without practical benefits.
