This paper suggests the minimum number of vertex guards algorithm. Given n rooms, the exact number of minimum vertex guards is proposed. However, only approximation algorithms are presented about the maximum number of vertex guards for polygon and orthogonal polygon without or with holes. Fisk suggests the maximum number of vertex guards for polygon with n vertices as follows. Firstly, you can triangulate with n-2 triangles. Secondly, 3-chromatic vertex coloring of every triangulation of a polygon. Thirdly, place guards at the vertices which have the minority color. This paper presents the minimum number of vertex guards using dominating set. Firstly, you can obtain the visibility graph which is connected all edges if two vertices can be visible each other. Secondly, you can obtain dominating set from visibility graph or visibility matrix. This algorithm applies various art galley problems. As a results, the proposed algorithm is simple and can be obtain the minimum number of vertex guards.

The purpose of this paper is to explore security guard's status and roles in society through media reports. Research method is to anlyze security Guard's 'Keyword Trend' and 'Keyword Frequency Analysis' by 'Big Kind' which enables 'News Big Data' analysis. The result came out by the analysis in sectional private security guard's history of settling down, growing up (quantity), and growing up (quality) by separating generations is that there are lots of attention and exposure from media about crime, security guard job, minimum wage, and 'Gabjil', but the images of security guard are recognized as victim of crime and 'Gabjil', and working in poor environment with minimum waged and ambiguous job, instead of people preventing crimes. In the future, stabilizing security guard's social status and work responsibility, and developing job professionalism are necessary to improve the images of security guard.

이 연구는 선행연구를 바탕으로 아파트경비원에 대한 감정노동에 대한 경비원들의 경험을 통하여 나타나는 문제점과 이에 대한 효율적인 발전방향을 제시하는데 있다. 심층면담 범주와 결과 크게 3가지로 나누었으며 첫째. 경비원들이 인식하는 감정노동인식은 높은 것으로 나타났다. 또한 주민들의 욕설 및 인격모독에 따른 스트레스 증가로 인해 의욕저하로 이어져 왔다. 둘째, 열악한 근무환경에 따른 휴게시간이 보장되지 않으며 경비업무 외적인 업무를 더 많이 수행하는걸로 나타났다. 셋째, 입주민들의 경비업무에 대한 이해도가 낮았으며 수평적 관계가 아닌 갑을관계로 인식하는 경향도 나타났으며. 또한 거기에 따른 부당한 업무지시로 인해 높은 노동강도를 보이고 있는 것으로 나타났다. 따라서 법 개정을 통하여 인권에 사각지대에 놓인 아파트경비원을 보호할 장치가 마련되어야 할 것으로 판단되며, 입주민들의 경비업무에 대한 이해도를 높이고 나아가 처우개선 및 근무환경개선이 필요하다고 사료된다.

The purpose of this paper is to study ways to improve the welfare of private security guards. For this reason, it was analyzed the actual situation of the private security guards' wage and welfare system. As a result of the analysis, the most important factors that affect the wages and welfare system of private security guards was such as contracting costs, the minimum wage level, professional duties. In particular, a private security guards have been recognized as the most low-level professionalism sorted by the simple laborers standard classification. Wages of guards in accordance with this recognition is only about 47% of major company on average, about 80% of the small business average. If the proposed future improvements include: First, we need to improve the professionalism of a private security. Second, It is established a mutual-aid project about private security guards. Third, It shall regulate the wage of private security guards on Private Security Industry Act. Fourth, we should adopt a selective welfare system.

A weakly visible polygon is an n-gon in the plane and consists of two mutually weakly visible chains. In this paper, we present an $O(n^2)$ time algorithm that finds a shortest watchman route among the routes with minimum links where a watchman patrols the inside of weakly visible polygons.

Coming to 21st century, the dangerous causes which threaten for safety of citizen's life is increasing. The national importance of facilitates which is dealing by special security officers are becoming target for enemy or terrorist. Therefore, securities in Korea are developing strongly. This study investigates for status and problem of the special security and aim to suggest the plan for development. The development of special security connects to the development of private security industry, the improvement of work environment for special security officers who are working in this ares, securing of man's ability, reality of salary, introduction of professional qualification system, reorganization of education system and the search system for preparing terror need to improve.

Even though, the Korean private Security Guard's industry is developing, it did not reached at the expected quality services because of the below cost tendering from flooded small security companies, consequently low pays and fragile benefits occur therefore, the skill level and morale decreased. Also, the private security guards field's education, training and development of expert certification system is not enough. One of the plans to solve these problems can be invigorate the certification system. The improving ways are suggested after the research and the analysis of the certification system as below. First, the qualification system to become a security leader will need to add directly related subject, skill examination and continuous refresh training. Moreover, it needs accurate needed the number of the securities and the reduction of the 1st examination exemption object. Second, the qualified system to be become securities will need to strengthen on standard of qualification and focus on skill evaluation, the job education need to state by the law, also exemption for applicant who approached requirements.
