The need of development of police officers' uniforms for the summer season has increased due to rises in temperature. This research developed a t-shirt typed of police officer's uniform for summer weather. We analyzed the design cases of national and international police officers' uniforms, similar types of uniforms, and t-shirts for summer weather. The satisfaction with current uniforms and preferences for these types of uniforms were surveyed with 1,062 police officers and public participants. Designs were developed and design opinions were surveyed with 1,011 public volunteers. A total of 584 police officers wore developed prototypes for two weeks, and surveys were conducted with 328 police officers to reflect the final design results. More than 80% of police officers have very satisfied or satisfied opinions of the developed designs. The study is expected to enhance police officers' satisfaction with the developed uniforms for summer weather.

High-rise and high-density apartment complexes has been built and supplied on a large scale in the metropolis and metropolitan areas since 1980s in order to solve housing shortage in cities. Recently they are raising deterioration problems for aging more than 20 years. moreover, those problems show very special characters such as simultaneity and a large scale. The purpose of this study is to propose a direction for the development of the evaluating indicators to measure the level of deterioration of apartments. The level of deterioration of apartments can be evaluated by housing performance. In order to evaluate the deterioration comprehensively, the housing performance indicators should be developed on the social, economical, and physical dimension. This study analyzed the concept of the apartment deterioration and compared housing performance indicators through literature review. First of all, when considering various factors in the evaluation of the deteriorated apartments, such as evaluating ranges, attributes and dimensions, housing performance indicators should be structured with the hierarchical framework. Second, housing performance indicators evaluating the level of deterioration of apartments should include social, psychological, and cultural aspects of home environments in order to understand adequately the attitude of the middle class toward services that apartments provide. Third, in previous researches, most criteria have been developed and weighted based on only expert opinions regarding performance indicators. So, It is necessary to include residents' opinions in developing performance indicators since they can provide more practical and feasible aspects the experts could not experience or understand.

This article reviews the multiscale nature of stress corrosion cracking (SCC) observed by high-resolution characterizations in austenite stainless steels and Ni-base superalloys in light water reactors (including boiling water reactors, pressurized water reactors, and supercritical water reactors) with related opinions. A new statistical summary and comparison of observed degradation phenomena at different length scales is included. The intrinsic causes of this multiscale nature of SCC are discussed based on existing evidence and related opinions, ranging from materials theory to practical processing technologies. Questions of interest are then discussed to improve bottom-up understanding of the intrinsic causes. Last, a multiscale modeling and simulation methodology is proposed as a promising interdisciplinary solution to understand the intrinsic causes of the multiscale nature of SCC in light water reactors, based on a review of related supporting application evidence.

An environmentally hot issue has arisen from the plan of Young-Wall Dam Construction at Tong river in Korea lately. The point at issue is which value is bigger between the water conservation for human use in future and the ecosystem protection for the intrinsic value of nature including animals and plants there. The purpose of this study is in the qualitative understanding of college students' critical thinking ability and opinion and the environmental values of them through the analysis of their writings. Various environmental values written in the 7th revised national curriculum of Korea are used as a criteria to investigate students' environmental values in their written opinions. Various environmental values are shown up to be handled such as the anthropocentrism, ecocentrism, pro-technology etc. Students of Dept. of Environment Teaching in the Kongju National University are the subject of this study. It shows that they have a deep understanding of the Young-Wall Dam issue and assert their opinions objectively and critically. Most of them(89.5%, n=17) are against the constructional plan of the Young-Wall Dam. Students who are for the plan are proved to have pro-technology value only and the others who are against to have various values including deer ecology.

In this study, the scientifically gifted students and the general students were compared in terms of the following components in cooperative teaming: whom they interacted with, to/from whom they gave/received help and why, and what kinds of the verbal interaction patterns they engaged in. The subjects were 4th graders. The data were collected through the investigation of the students' perception and videotaping of the small group interactions of each group. The results showed that the gifted students interacted with most students in their groups. They complemented each others' opinions and their discussion was enriched through their interactions. On the other hand, the interactions of the general students occurred mostly around a leader, and more teamed students explained the content to the less teamed students. Predominantly, the gifted students' most verbal behaviors were related with the teaming contents. Most frequent verbal behavior were a giving specific information and an explanation of their opinions. The general students, however, gave simple and short information, and more often they showed the management behaviors, such as encouraging participation and suggesting their directions.

International sales contract, in general, is concluded through the exchange of written forms which contain each of their own business terms and conditions among the contractual parties. To illustrate, A sends the other an offer on A's general terms and conditions of business and B accepts the offer subject to the use of B's own general terms and conditions. Where the two sets of terms and conditions do not coincide, the question may arise whether the parties(A and B) have contracted and, if so, whose general terms and conditions apply. This situation is referred to as "the battle of forms". This article would try to make, in terms of the battle of forms, a comparison between the classical perspectives and opinions which are based on the principle of the English Common Law and the modernistic perspectives and opinions which are applied to the provisions in the UCC, CISG, and PICC. Therefore, the aim of this article is to provide the increase self-consciousness with respect to the battle of forms between the contractual parties that may frequently happen in the international business transactions and will pave the way for further research in the future.

Bill of lading means the transport document ("marine", "ocean" or "port-to-port" or similar), however named, covering sea shipment only. Data in a bill of lading, when read in context with the credit, the document itself and international standard banking practice, need not be identical to, but must not conflict with, data in that document, any other stipulated document or the credit, according to UCP 600 and ISBP. This article has provided the general guideline of the discrepancies on the basis of UCP 600, ISBP 681 and the ICC Banking Commission Opinions, for the solution of the unpaid problems of the credit transactions. I have studied especially the ICC Banking Commission Opinions and the DOCDEX Decisions on the bill of lading after UCP 600, the international standard banking practice (ISBP 681), and the recent Korean cases. As such, this article would fill a need gap in the market between the general principles in the UCP provisions and the daily job of the practitioner. The credit practitioners are suggested to this resulting guidance whenever doubts arise as to how to check the credit documents in daily practice.

The recent successes of systems like Google, Wikipedia and InnoCentive suggest that the time is now ripe for more such systems. Thus, we want to explore these systems and exploit them from a viewpoint of social psychology prior to technological progress. First of all, we examine the difference between 'wisdom of crowds' and 'crowd psychology'. There are two classes, which are for senior management major students. Conditions of two are same, except a class time. Forty five students in one class are tested for this experiment. They form a group with five people and are divided into 9 groups. In a case of a morning class, peer-to-peer evaluations are given to individuals in a class when a group presentation for a final project is given. On the other hand, in a case of afternoon class, peer-to-peer evaluations are given to each group in a class. The result is quite fruitful. The first is that an expert's evaluation for a project agrees with students, who are beginners in this field in the degree of more than 95%. However, in the case of afternoon class, students' group evaluation turns out to agree with an expert's one less than 53%. Morning class experiment result proves the truth of collective intelligence again. It tunrs out independent and confidential opinions are more cost effective and give right answers to questions than group opinions.

Consumers repeatedly make small sum purchases through business-to-consumer contracts, usually without incident. Consumer areas have been increasing; therefore, consumer disputes have been occurring frequently as well. In international consumer transactions, it is not easy to solve consumer disputes by applying the laws of different countries. Resolving disputes by using the consumer arbitration system can be a measure to protect consumers. In the U.S., a class arbitration is being operated as a mixed dispute resolution system of class action and arbitration. Consumer Arbitration has long been a controversial issue in the U.S. It is therefore a lesson for us to examine related cases. A recent U.S. Supreme Court decision, DIRECTV v. Imburgia, was looked into and after a summary of the facts, issues, and opinions and opposing opinions that had a tight controversy, a close analysis was done. The analysis through this judgment is as follows: first, the contraction of consumer protection; second, the expansion of the Federal Arbitration Act scope; third, the class arbitration's restriction; and fourth, the submission of the arbitration fairness act.
