The area of security service has been maintaining the high growth curve annually by improving security consciousness from increase of the income and the progress of public services's level by the accomplishment in the info-communication field, recently the demand for unmanned security system is extended form commercial purposes into public offices and individual's houses. In addition to, the possible distance of offering services is scheduled to magnify. At the period when security company's influence has been becoming significant, the injustice transaction is the serious factor which obstructs the development of security companies. Therefore, it is urgent thing to devise counterplans to extirpate injustice transactions. There are the legalistic approaches of the breakthroughs against injustice transactions. One thing is settling the standard of the judgment and the other is renovating the provision of injustice transactions. Utilizing the principles of the fair competitions and importing self-obedience programs within the range of trade actions which is permitted by law, acted as the system approach. Moreover, there are such three things which can achieve mutual balances as establishing the range of the permitted action toward business corporations, applying spontaneously the fair competition principles and introducing the system of standard agreements. Gong further, this can establish order of security service areas and control them. Besides, it is possible for every organizations to make and operate the system appropriately by importing the self-observance system.

Human trafficking is a booming underground business and is the fastest growing and criminal activity in today's society. The use of coercion or fraud marks the territory of trafficking. Most people trafficked suffer constant threats, violence, and forced acts while imprisoned by their traffickers. Such human trafficking entails significant problems not only for the victims but also for the economies and community health. Large corporations overseas have also been known to partake in the sex slave industry. Another hidden cost to the global economy is the cost of law enforcement and anti-trafficking measures being implemented. Further, sex Trafficking carries many potential health consequences, one of the biggest risks is HIV infection. That means, sex trafficking is an engine of the global AIDS epidemic with one study portraying nearly fifty six percent of all sex slaves having HIV or AIDS. Therefore, many of people are being infected with HIV and many other diseases every day through contact with the sex slave industry costing millions to society and the global economy. in this study, the author presents a case study of trafficking against Nepalese women. Nepalese women being trafficked are found to have a high prevalence of HIV infection. In conclusion and discussion, a few of solutions needed to be addressed for controling human trafficking for sex slavery suggested.

Tourism in Thoi Son Islet has been the advanced model for rural tourism in the Mekong Delta region since the 1990s. The continuously rising number of tourists, however, has also created problems that affect sustainable rural development. To understand these problems, this research analyzed how rural tourism has been operated through the methodology of a stakeholder network. After investigating the network among key stakeholders (Ho Chi Minh travel agencies (HCMTAs), local travel agencies (LTAs), and local residents, the result showed that in the current model, HCMTAs and LTAs have played the role of connectors, working as hubs to shift tourists (demand) to match local residents (supply), with the networking being dominated by signed contracts (formal networks). The networks between LTAs and local residents are both formal and informal. Inter- and intra-networks among local residents are dominated by informal networks of established working relationships based on networks of family, friends, and neighbors. Moreover, this research has found that there is no cooperating network among LTAs. Among owners of tourist sites was not also found cooperating network. The primary motivating factor for these stakeholders is price competition; this has led to a disproportionately small share of revenue for local stakeholders, with most tourism revenue going to HCMTAs. Additionally, because of the high competition among local stakeholders, this results in local stakeholders having little or no negotiating power when conducting business with HCMTAs. Meanwhile the Tien Giang Tourism Association is inefficient in fostering cooperation among local stakeholders to increase their negotiating power.

As the society turns into more of an information an technology centric society, the importance of information security is being increased these days. Recently, as the number of leaking accidents of personal information and valuable industrial technology is on the rise, every field of industry endeavors to come up with a security solution. In particular, since defense industry is a field where it establishes national defense power that is essential of national security, it requires higher standards of security solutions than any other ordinary fields of industry. According to Defense Industry Security Work Instructions, defense industry firms from security organizations and employ a security worker corresponding to the firm's scale and conditions. In an environment where essential information and technology are stored and managed in information and communication system or storing media, the duty and role of IT security workers are crucial. However, there is a shortage of systematic analysis on the work of IT security workers and development of curriculum to enhance their professionalism. Thus DACUM process, a job analysis technique, was used to identify IT Security workers' duties and responsibilities and verify the validity and credibility of the deducted results from the survey. The findings of this study will help in development of IT security duty in defense industry and can be used as baseline data for the development of curriculum and amendments of related regulations.

Since the September 11, 2001, transnational crimes and terrorism have increased, the importance of border security has been emphasized and integrated CIQ capability has been required. The U.S., Canada, and Australia are consolidating CIQ to strengthen border security, focusing on strengthening travelers and goods immigration control and airports, ports and land border security. In 2003, the U.S. established the Customs and Border Protection(CBP) under the Department of Homeland Security. Canada also established the Canada Border Services Agency(CBSA) under the Public Safety Canada in 2003. The Australian Customs and Border Protection Service was integrated with the Department of Immigration and Border Protection(DIBP) and the Australian Border Force was established in 2015. However, Korea operates a distributed border management system for each CIQ task which is unable to respond to complex border threats such as illegal immigration, entry of terrorists, smuggling of drugs, and gun trade in the airports, ports and land borders. In order to solve this problem, it is possible to consider integrating sequentially the customs and quarantine services which have high similarities, and to integrate the entire CIQ tasks with the Korea Customs Service delegated to the immigration control duties in the mid to long term. There is also a plan to benchmark the CIQ single accountability agencies in the U.S., Canada, and Australia in accordance with the Korean situation and to establish a new integrated border security organization.

The market of public-private partnership (PPP) projects has reduced from 9.4 trillion won in 2007 to 4.5 trillion won in 2012. However, the need of PPP projects is brought up by a massive down scale of government financial business. Previous studies regarding PPP projects mostly evaluate profitability from the financial perspective or analyze risk factors as a whole. Although PPP projects generally have complex structure involving diverse stakeholders, such as contractor, financial investor, and special purpose company (SPC) operators, existing studies have rarely considered the different viewpoints of PPP project stakeholders. Therefore, purpose of this study is to develop a structural equation model (SEM) considering the diverse stakeholders of PPP projects. To this end, the authors first reviewed the organizational structure of PPP projects. Next, the identification of the factors affecting project profitability are done via comprehensive literature reviews. After that, we conducted in-depth interviews and questionnaire surveys to reflect stakeholders' perspectives (contractors, financial investors, and SPC operators). As a result, a SEM model is developed to analyze direct and indirect effect on the PPP project performances. Finally, using the analysis results, relevant implications and directions for improvements are discussed. The prediction of the business performance of contractor, financial investor, and SPC operator is expect to be possible through the model developed and supports the strategy deduction that is appropriate for the participants.

베트남은 자연재해로 인해 매년 평균 750명 이상의 사망자가 발생하고 있으며, 경제적인 피해 또한 한해 GDP의 1.5%에 달하고 있다. 저먼워치(Germanwatch)의 2010년 세계기후위험지수(Global Climate Risk Index, GCRI)의 전 지구적 기후재난에 관한 국가별 순위 조사에서 베트남은 4위에 기록되었다. 베트남의 자연재해는 상당 비중이 풍수해에 집중 되어 전체 재해의 86%를 차지하고 있고, 이는 대부분 해안 지대와 강 유역의 홍수 및 범람에서 비롯된 것이다. 베트남 전체인구의 약 70%가 상습적 홍수와 범람 발생 지역인 해안가에 거주하고 있어 재난에 예방 및 복구 관리에 대한 국가 차원의 방안이 시급한 실정이다. 본 연구에서는 과거 30년간의 풍수해 관련 재해에 대한 기록상 추이를 통해 공간적으로 재난에 취약한 지역적 분포를 살펴보고, 그 지역의 지리적 특성을 분석하여 재해에 관한 종합적 고찰을 하였다. 벨기에 루뱅대학 부설 재난역학연구센터(Centre for Research on the Epidemiology of Disasters, CRED)의 EM-DAT를 이용하여 과거 기록상의 개괄적인 재해양상에 관한 추이를 살펴본 결과 대부분의 재난은 풍수해에 집중이 되어 있음을 분석하였고, 베트남 풍수해조정기관인 홍수및폭풍조정중앙위원회(Central Committee for Flood and Storm Control, CCFSC)의 최근 30년간 풍수해에 관련된 통계 자료를 정리하여 상습적 재난 피해지역을 지도상에 표시하였다. 이 때 지구지도제작운영위원회(International Steering Committee for Global Mapping, ISCGM)의 D_WGS_1984 Datum을 바탕으로 한 베트남 shape file을 이용하여 풍수해에 따른 인명피해, 경제적 손실, 발생횟수 등에 관한 사항을 일반화 시켜 재난 취약지역을 지리적으로 분석하였다. Thanh hoa, Quang nam, Binh Dinn, Camau성이 풍수해와 관련된 재난에 취약하게 노출되어 있음을 도출하였다. 재난에 상대적으로 취약한 이들 지역에 대한 현재의 재난 관리는 어떻게 이루어지고 있는지에 관해 현재의 풍수해관리 사업단의 조직적 구조와 그 기능 및 역할을 살펴보고, 국제적 원조 사례를 분석하여 상습적으로 재난의 위험 지역에 대한 지속적인 관리와 복구를 어떻게 이루어 나갈 것인지에 대한 방안 및 제언에 관하여 논의하고자 한다. 베트남의 재난 관리에 관한 지리적인 종합 분석은 기존 양상의 재해에 대한 방안을 구축하는 데 대한 제언뿐만 아니라 기후변화와 관련된 재난을 예측하고 관리 방안을 설정하는 데 기초 자료를 제공할 수 있을 것이다.

The military is an organization where reliability and availability take much more importance than in any other organization. And, in line with a recent trend of putting emphasis on 'system readiness', not only functions but also availability of a weapon system has become one of achievement targets. In this regard, the military keeps spares for important facility and equipment, which is called as Maintenance Float (M/F), in order to enhance reliability and availability in case of an unforeseen event. The military has calculated yearly M/F requirements based on the number of equipment and utilization rate. However, this method of calculation has failed to meet the intended targets of reliability and availability due to lack of consideration on the characteristics of equipment malfunctions and maintenance unit's capability. In this research, we present an analysis model that can be used to determine an optimal M/F inventory level based on queuing and absorbed Markov chain theories. And, we applied the new analysis model to come out with an optimal volume of K-1 tank M/F for the OO division, which serves as counterattack military unit. In our view, this research is valuable because, while using more tractable methodology compared to previous research, we present a new analysis model that can describe decision making process on M/F level more satisfactorily.
