The club culture is not something unified. Rather, it is a group of subcultures which share intertwined areas. And it keeps its own dress code, dance style, music genre along with series of authoritarian and unlawful rituals. For young adults, a club is a new cultural space to enjoy in reasonable price and they can express themselves without thinking much about others. A club creates its unique mass culture by producing continuously changing and experimental fashion styles. As the club culture’s influence becomes powerful, the club market was established and experimental fashion styles are wide spread among general public, young adults who try to express their unique characters and even fashion-leading industry. The study results are as follows. First, dance club and its derivative, rave is symbolic axles and the center of social activity. They are also defined as culture which is related to specific space that continues to present and change sound and style. Second, the definition of clubber in a dictionary is club member or a person who is united with others. Third, based upon clubbers' fashion styles in Hongdae and Kang-nam areas, there are 5 different images including sexy casual, lingerie, dynamic, chic style and feminine style. Fourth, based upon case study above, to take unique life style of fashionista that leads fashion with trendy fashion style into account, we suggested five designs which are unique, sensitive and trendy. Fifth, through analyzing clubber generation and design factors of clubbers' fashion style combined with various trend, unique brand was developed to meet the demands of clubbers who want differentiated images and leading styles.

In the fisheries industry, the cost of oil Is the greatest factor, contributing 25% 40% of the cost of production. In order to support fisheries, the government has supplied large amounts of money for oil to the fisheries industry. However, the elimination and restriction against the subsidy of fisheries has been actively discussed throughout international organizations Including the WTO. The purpose of this thesis is to study the existing issue of subsidies on the fisheries Industry, which is currently disputed in international organizations, and predict a future policy about the oil supply that considers the most important factors on fisheries. In chapter 2, the paper begins by outlining the tendencies of discussion in relation to the subsidy on fisheries among international organizations, and categorizes them on the basis of their types. Chapter 3 defines the current conditions and characteristics of the Korean subsidy on fisheries and analyzes which portions of the subsidy on fisheries should be eliminated first when it is prohibited. In chapter 4, procedures and problems for producing tax-free oil are discussed, because tax-free oil has a higher possibility of being ruled out. Chapter 5 proposes a reasonable plan concerning oil supply policies for maintenance or enrichment of the fishing industries, post the elimination of subsidies. Conclusions were drawn in eight areas as a result of this study: 1) securing the large storage of oil, 2) extending customers of oil to include non-fishermen, 3) coordinating the segmentation of marketing area, 4) diversification of the sales goods, 5) producing oil sales experts, 6) developing original brands, 7) expanding the purchasing area to buy oil in the international market, and 8) operating funds to stabilize oil price. It would not be appropriate to wait until international organizations decide to ban the subsidy of fisheries. Corresponding plans ( such as securing the large storage of oil) tend to be large scale and long-term projects because they take a number of years, from designing the oil storage tank to selecting the proper region and initiating the construction. Therefore, it is strongly suggested that any extensive and time consuming projects including preparation for the tax-free oil should be completed in new actions before the ban by the international organizations.

To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain.

다수경로 알고리즘은 비루프경로(Loopless Path: 또는 Simple Path)와 루프경로(Loop Path)를 탐색하는 방안으로 대별된다. 알고리즘의 난이도 측면에서 일반적으로 비루프경로를 탐색하는 방안이 루프경로를 탐색하는 방안보다 많은 노력이 소요된다. 바꾸어 말하면, 루프경로 탐색방안이 알고리즘의 이해 및 활용성 측면에서 용이하다는 장점이 존재한다. 루프경로탐색방안에서 경로삭제방식(Path Deletion Method)이 가장 효율적인 알고리즘으로 알려져 있다. 경로삭제방식은 K번째의 최적경로를 탐색하기 위하여 K-1번째의 경로의 탐색금지 상황설정이 필요하며, 이를 네트워크의 변형된 확장형태(Enlarged Transform)를 통하여 추구하는 방식이다. 그러나 이 알고리즘은 경로상에 노드 및 링크의 반복이 허용되는 루프를 생성시켜 교통망에 적용하기에는 한계가 존재하는 단점이 있다. 본 연구에서 링크표지를 활용하여 루프를 제거하는 방안을 개발한다. 이를 위해 K-1번째 확장네트워크에서 링크표지를 갱신하는 과정에서 대상링크와 전 링크의 부분경로와의 관계를 고려하여 루프가 생성되지 않도록 링크표지를 확정하여 원천적으로 루프의 생성을 방지한다. 본 연구에서 제안하는 비루프 알고리즘은 노드비루프와 링크비루프로 구분되며, 노드비루프는 경로 상에서 노드의 반복이 존재하지 않는 일반적인 단순경로(Simple Path)를 의미하며, 링크비루프는 경로 상에 링크의 반복이 존재하지 않는 경로를 의미한다. 특히 링크비루프는 도시 교차로에서 발생하는 U-턴, P-턴의 덩굴망 통행행태를 설명하기 위한 중요개념으로 확대 정의된다. 사례연구를 통하여 제안된 알고리즘의 활용성을 검증한다.

The purpose of this study is to introduce the Double Punch test method which is an indirect testing method of tensile strength of concrete, and to compare with the tensile strength of concrete as determined by the split-cylinder test, a practical method for performing the Double Punch test to obtain the tensile strength of concrete is proposed and recommended for general use. In this study, the dimensions of cylindrical specimens used in the Double-Punch test were 15X30cm, 15X15cm, 10${\times}$(20cm, and 5${\times}$l0cm, and in the split-cylinder test were 15${\times}$(30cm, 15${\times}$(15cm, and 10${\times}$(20cm. And the diameters of loading punches used in the Double-Punch test were 1.5cm, 2.5cm, and 3.5 cm. The results obtained from tests are summarized as follows ; 1. In the split-cylinder test, the tensile strength of concrete by the linear elasticity theory is similar to that of plasticity theory. 2. Both split-cylinder test and Double-Punch test, tensile strength of concrete is increased with decreasing specimen size. This tendency is identical when the ratio of specimen diameter to height is 1: 2, but that tendency is quite different when the ratio is 1: 3. In the Double-Punch test, if specimen size is constant, by increasing the punch size, tensile strength of concrete is increased, too. 4. Using a 15 ${\times}$( 15 cm cylinder specimen and 3.5 cm diameter punch in the Double Punch test would give the most uniform and consistent result in tensile strength, and the result showed a gQod correlation with splitting tensile strength from 15 x 30cm specimen. 5. In order to obtain satisfactory results and to nuninuze variability, it is proposed that specimens of 15 cm in diameter and 15 cm in height with two 3.5 cm diameter punches should be used. It seems, therefore, reasonable tt) take f't=0.0024 P(kg / cm$^2$) as a working formula for computing the tensile strength in the Double Punch test for concrete.

The national parks of South Korea take up an area of 6,726 ㎢, which accounts for 6.7% of the national land. They are national conservation areas with their area made up of 59.1% of land (3,972.6 ㎢) and 40.9% of seawaters (2,753.7 ㎢). And in 2019, the national parks are classified by type into 17 mountainous, 4 maritime or coastal, and 1 historical site. Here, the maritime or coastal nation parks are lately spotlighted as landmarks in maritime tourism. However, the area of the maritime or coastal national parks is continuously dwindling due to conflicts between the residents in the parks and Korea national park service, the continued pressure with respect to the regional tourism development and private investments, and the abolition of parks in relation to allegedly breached private properties. This study identifies the issues with the operation and management of national parks as caused by the abolition of parks and the reduction of areas, and goes from there to do research with the aim of suggesting an institutionalized improvement plan with a view to more useful operation and management of the maritime or coastal national parks. As a result, the natural resources in the sea and on land should be surveyed again to establish the standard for use-specific zoning and reorganize the park areas in adjusting the national park areas. Second, the use-specific districts need to be reviewed for their reorganization that meets the designation requirements by focusing on the characteristics of the different national parks with a view to ensuring reasonable natural conservation in the maritime or coastal national parks. Third, various support facilities for residents such as public path, lodgings, and rentals need to be created to reduce the conflicts between Korea national park service and those who live in the parks.

If a transient occurs in a nuclear power plant (NPP), operators will try to protect the NPP by estimating the kind of abnormality and mitigating it based on recommended procedures. Similarly, operators take actions based on severe accident management guidelines when there is the possibility of a severe accident occurrence in an NPP. In any such situation, information about the occurrence time of severe accident-related events can be very important to operators to set up severe accident management strategies. Therefore, support systems that can quickly provide this kind of information will be very useful when operators try to manage severe accidents. In this research, the occurrence times of several events that could happen during a severe accident were predicted using support vector machines with short time variations of plant status variables inputs. For the preliminary step, the break location and size of a loss of coolant accident (LOCA) were identified. Training and testing data sets were obtained using the MAAP5 code. The results show that the proposed algorithm can correctly classify the break location of the LOCA and can estimate the break size of the LOCA very accurately. In addition, the occurrence times of severe accident major events were predicted under various severe accident paths, with reasonable error. With these results, it is expected that it will be possible to apply the proposed algorithm to real NPPs because the algorithm uses only the early phase data after the reactor SCRAM, which can be obtained accurately for accident simulations.

It is important who is bound by an arbitration agreement and what is the subject of the agreement in resolving disputes through arbitration. However, there are no provisions on them in the Korean Arbitration Act. Where an arbitration agreement is valid, the persons who are bound by the agreement cannot bring the claims which are the subject of the agreement to a court. Therefore, in determining the subjective scope of the effect of an arbitration agreement, we should make allowances for the essential qualities of arbitration to ensure the efficient resolution of disputes on the basis of the parties' agreement, and take caution not to infringe on the rights to be tried in court. Where the rights or legal relationships constituting the dispute that is the subject of the arbitration agreement have been assigned, the effect of the arbitration agreement between the predecessor and the other party should be extend to the successor, when it is agreed to transfer the status under the arbitration agreement to the successor between the three. However, in the absence of such an agreement, it is necessary to weigh the interests between the predecessor, the other party and the successor to determine whether the arbitration agreement has any effect on the successor. Arbitration is a method of resolving disputes based on the agreement of the parties. If it matters whether third parties who are not parties to the arbitration agreement is bound by the arbitration agreement or may invoke it, it should be resolved according to the intentions of the parties. Where the parties to an arbitration agreement have agreed to allow a third party to invoke the arbitration agreement, the effect of the arbitration agreement will extend to the third party. However, even if the parties to the arbitration agreement have not expressly agreed on this, when it is recognized that the parties have sought to resolve the dispute through arbitration even in relation to a third party by exploring the reasonable intentions of the parties, the effect of the arbitration agreement will extend to the third party.

본 연구는 한국 중 고등학생을 대상으로 학교에서 이루어지는 기존의 상벌점제도와 자기결정성 이론에 근거한 교육환경요인들이 학습 성과에 어떠한 영향을 미치는지 학습동기의 매개효과를 중심으로 살펴보고자 하였다. 이러한 목적을 위해 서울시에 위치한 중 고등학교를 다니는 학생 202명을 대상으로 자기결정성 교육환경요인, 학습동기, 학습 성과 척도로 구성된 설문지를 실시하였다. 분석 결과 첫째, 자기결정성 이론에 기반 한 교육환경 변수들 중 자율성은 내부, 외부 학습동기에 긍정적인 영향을 주고, 자신감은 내부, 합리적 동기를 높여주며, 유대관계는 무동기를 낮추는데 긍정적인 효과가 있음을 확인하였다. 둘째, 최근 체벌에 대한 대체체벌로서 시행되고 있는 상벌점제도(Reward and Punishment Mark System)가 학생들의 학습동기에 유의미한 영향을 미치지 못하는 것으로 나타났다. 셋째, 학습동기 하위요인이 학습 성취에 미치는 영향을 살펴본 결과 내부동기가 수업참여의지와 학습 성과에 모두 유의한 정의 관계를 보이는 것으로 나타났다. 위의 연구결과를 토대로 자기결정성 이론에서 제시하는 자율성, 자신감, 유대관계에 대한 배려가 학습동기를 높여줌으로써 수업참여 의지를 높이고 학습 성과를 높인다는 사실을 확인함으로써 교육 분야에서 벌점제도 이외에 새로운 접근법을 필요하다는 것을 시사한다.
