공기업(公企業) 비효율성(非效率性)의 근본원인을 소유구조상(所有構造上)의 문제, 경쟁부재(競爭不在)의 문제, 지나친 정부규제(政府規制)의 문제로 이해할 때 그동안 공기업관련(公企業關聯) 정책(政策)이 소유구조상의 해결책인 민영화정책(民營化政策)에만 지나치게 편중됨으로써 경제력집중(經濟力集中)이나 증시문제(證市問題) 등으로 인해 공기업(公企業) 비효율성(非效率性)의 치유가 오히려 지연되고 있다는 시각에서 본고는 출발하고 있다. 시장기능(市場機能)의 활성화를 통한 효율성제고(效率性提高)가 공기업정책(公企業政策)의 궁극적인 목표라고 할 때 공기업의 비효율성(非效率性) 문제는 공기업관련(公企業關聯) 산업(産業)의 경쟁정책적(競爭政策的) 차원에서 문제점들을 파악하고 해결책을 모색할 필요가 있다. 따라서 공기업분야에 시장기능(市場機能)이 정착되기 위해 민영화(民營化), 경쟁도입(競爭導入), 규제완화(規制緩和) 등의 효율성 제고수단들의 총체적이고 유기적인 연계가 필수적이다. 이러한 시각에서 본고는 민영화 등 공기업관련(公企業關聯) 경쟁정책(競爭政策)중 구조적(構造的)인 측면을 주로 살펴보고 있다. 공기업(公企業)의 비효율성(非效率性)을 공기업 자체의 내적(內的) 비효율성(非效率性)과 시장에서의 배분적(配分的) 비효율성(非效率性)으로 구분할 때, 내적 비효율성 못지않게 배분적(配分的) 비효율성(非效率性)이 심각한 것으로 보인다. 한국통신(韓國通信) 등 대표적 공기업 6개와 10대(大) 민간(民間) 대기업집단(大企業集團)의 수익률(收益率) 비교(比較) 등에 따르면 이들 공기업이 독점적(獨占的) 시장구조하(市場構造下)에서 민간독점기업적(民間獨占企業的) 행태를 취해 왔다고 판단된다. 한편 상대적으로 경쟁도입이 활성화되고 있는 통신산업(通信産業)의 경우 요금의 변화추이는 경쟁도입(競爭導入)이 배분적(配分的) 효율성(效率性)을 증진시키고 있는 것으로 나타나고 있어 시장구조(市場構造)를 경쟁적으로 변화시키는 것이 공기업정책(公企業政策)에서 절실하다고 판단된다. 구조적(構造的)인 경쟁정책(競爭政策)을 다루기 위해 본고는 사업다각화(事業多角化)라는 시각에서 6대(大) 공기업관련산업(公企業關聯産業)의 산업련관분석(産業聯關分析)을 통해 공기업이 상당한 전후방효과(前後方效果)를 갖고 있기 때문에 단순 민영화에 따른 수직적(垂直的) 독점력(獨占力) 확산을 고려하면서 구조적(構造的) 정책(政策)을 취할 필요가 있음을 지적하고 있다. 따라서 독점공기업(獨占公企業)을 민영화함에 있어서 시장구조를 보다 경쟁적(競爭的)으로 전환시킬 필요성이 크다고 판단된다. 1993년 민영화계획(民營化計劃)의 범위가 불충분하고 그 계획조차 지연되는 현상황을 고려할 때 민영화정책의 보다 강력하고 광범위한 실행이 필요할 뿐만 아니라 공기업분야에 경쟁적(競爭的) 시장구조(市場構造)가 정착될 수 있도록 유도하는 것이 공기업 관련 구조적(構造的)인 경쟁정책(競爭政策)의 핵심이라고 본다. 또한 본 논문은 공기업이 원래의 설립목적(設立目的) 이외의 다른 사업분야에 진출하는 것을 허용할 것인가에 대하여 구조적(構造的) 경쟁정책차원(競爭政策次元)에서 기본방향을 제시하고 있다.

This study analyzed how North Korean defectors recognized and overcame conflict in the South Korean job culture during the course of entering and settling into South Korea, and the association between their old career and adaptation within their new careers. The study selected 13 employed participants who entered South Korea more than five years ago and experienced working. Interviews were conducted over the course of five years. The topics were analyzed after performing interviews 60 to 120 minutes long by recording and transcribing the recordings and using semi-structured questionnaires for the 13 people. The results reflected the job environment in North Korea, their career background, factors for a successful new life, their constant efforts for employment, the difficult adaption to South Korean life, pursuing job stability, accepting South Korean culture, and career compromises. The results of this study are as follows. First, they undergo difficulty in the course of selecting jobs due to the converted environment from passivity to autonomy. Second, they cannot use their previous job history and they complained about prejudice and the lack of job information. Third, major problems included their lack of adaptability, stress, and loss of economic power. The study suggests that these North Korean defectors undergo an integrated course of cultural learning. Fourth, they were hardly able to adapt. Fifth, they tried to overcome conflicts of job culture according to their personal characteristics.

In the past, the domestic construction industry mainly comprised quantitative investment through the supply of labor force, however, there have recently been opinions that there is a need for qualitative investment in the workers in order to obtain competitiveness in construction markets. Accordingly, there are much re-education courses for workers in the construction industry, but there is much negative awareness as to the efficiency of the current re-education course due to many problems. This study aimed to examine the problems o f currently executed re-education courses and proposed an improvement plan for the qualitative enhancement of domestic construction re-education. Thus, a multiple regression analysis was conducted to deduce two core problems an improvement plan. The improvement plan for the problems comprised the NCS/CDP-based integrative education program through an AHP. The contribution of this paper will result in the execution of a more effective construction industry re-education program, and the result of such program to achieve qualitative growth in the workers in the construction industry

In this study, the load capacities and behaviors of a shotcrete member with steel supports, as composite member, are investigated numerically by using a fiber section element. The cross section of a shotcrete lining with steel support is divided into a bundle of fibers, which are allocated nonlinear stress-strain relations and used for determining internal forces. To verify the used approach of the finite element method for shotcrete with steel supports, the load-displacement relations of shotcrete lining obtained by numerical analysis are compared with existing experimental results and are analyzed with the stress distribution of the shotcrete and steel support obtained numerically. As a result, it is shown that the proposed approach can predict the load capacities of each material and the overall nonlinear behavior of shotcrete lining with steel supports. The change of location of the neutral axis and the flexural resistance ratio of each material are also derived from the stress distribution of the cross section of the shotcrete lining with steel supports. From the results, it is concluded that the flexural resistance performance of steel support should be considered in shotcrete lining design.

The purpose of this study is to find out the way to improve the funding system of Korean animation, which will lead the establishment of virtuous circle of Korean animation industry. The funding structure of Korean animations in the period of 2005-2009 is analyzed to find out that the funding surveyed to find out that the domestic funding source for Korean animation has reached its limitation. Without any active involvement of public fund, this will result in the shrink of Korean animation industry with heavy reliance on foreign capital and limited quality of Korean animation. This is not only a serious problem of Korean animation industry, but also the problem of Korean cultural identity and variety because it is related with the diminish and degradation of Korean children and family content. Meanwhile, in France and Canada, which are the major co-production partners of Korean animation, the animation production is being activated by the full support of government fund system, because the animation is regarded as the important genre which plays a critical public role in establishing the cultural identity and variety of such countries. Improvement of Korean animation funding system is not pursued by more injection of public fund into the industry. It should be designed to facilitate the investment from the private sector by improving the profitability of Korean animation. This goal can be achieved by public fund with annual budget of 25 billion Korean Won supporting the distribution and production of Korean animation. Discussion should be needed for securing the funding resources such as establishment of new animation fund or utilization of existing fund.

During the recent years, cyber attacks have been increasing both in the private sector and the government. Those include the DDOS cases in 2009, the Blue House cyber attack, bank hackings etc. Cyber threats are becoming increasingly serious. However, there is no basic law related to cyber security at present, and regulations related to cyber security are scattered in various domestic laws. This can lead to confusion in the application of the law and difficult to grasp the regulations related to cyber security. In order to overcome this situation, the bill on the prevention and countermeasures against cyber crisis was initiated in 2006, but it has been abrogated. Since then, it has been repeatedly proposed, but it has been abrogated repeatedly due to the overlapping of existing laws and concerns about infringement of personal information. The most recent initiative was the National Cyber Security Act, which was initiated by the government in January 2017. The act focuses on resolving the absence of a basic law related to cyber security, strengthening its responsiveness in the event of a cyber security crisis, and fostering security strength. Therefore, this study seeks to contribute to the establishment of National Cyber Security legislation as a basic law of cyber security by examining the necessity of National Cyber Security legislation through comparative legal analysis with existing domestic laws related to cyber security and suggesting policy implications.

For the purpose of effective utilization of domestic second-grown larch as structural members, post and beam construction applying traditional construction to Japanese larch glulam members was adopted with processing by machine pre-cut method. In general, horizontal shear test by KS F 2154 is conducted to assess the horizontal shear properties of the wooden structure by post and beam construction. The frame was consisted of post and beam member with appropriate fasteners, and members have their own processed parts (notch, hole, etc.) that can be well-connected each other. The shear wall was consisted of the frame with screw-nail sheathed panel (OSB). The results of horizontal shear loading tests without vertical loads conducted on the frame and the shear wall structures, the maximum strengths were about 1.9 kN/m and about 9.7 kN/m, the shear rigidities were about 167 kN/rad, 8198 kN/rad, respectively. The strength proportion of the frame specimen was about 20% of the wall's and about 2% in initial stiffness. Nail failures are remarkable on the shear wall specimen with punching shears and shear failures. The shear load factor for the shear wall specimen by the method of Architectural Institute of Japan was 1.5, which was obtained by the bi-linear method. Loading method should be considered to obtain smooth load-deformation relationship. For the better shear performance of the structures, column base and post and beam connections and sheathed panel should be further examined as well.

As ICT technology becomes advanced, the importance of future internet is emphasized and in part of that, M2M (Machine-to Machine communications) is magnified in terms of importance and usage in public and private sector. M2M is emerging as a next generation strategic industry but there is no existing analyzed data or market classification, so it disrupts establishing policies on the M2M industry. As the technology is progressing, the evolution from M2M to IoT (Internet of Things) has started and many countries actively try to find technological trend through market analysis in order to develop new growth engine. Therefore, in order to strengthen competitiveness, we should secure differentiated capabilities in industry and service. This article examines Korea's domestic market and international market trends in IoT and analyses the economic impact of the IoT industry using quantitative methodology and evaluates relations between the IoT industry and other relevant industries. As a result, the effect of IoT industry on production inducement is KRW474.6 billion; the effect on value-added inducement is KRW314.7 billion; and it is measured that 3,628 jobs will be created by the IoT industry.

Porous walkway blocks are constructed for the purpose already, but reserved water is easily consumed due to the bigger permeability than necessary. Furthermore, porous structure reduces the strength of blocks, which resulting cracking and settlements in walkways. In this study, we suggested a solution for given problems by determination for the location of minimum principal stress in walkway blocks against moving foot loads in order to design and verifying the determined location of minimum principal stress. An optimum design with a verification example for determined location of minimum principal stress have been presented in a two dimensional Block member on elastic foundation for pedestrian walkway for reserving water inside. The minimum value for sum of shear forces is found when ${\times}1$ is 58.58 mm(30% of total span, 200mm), while the minimum deformation is located at ${\times}2=80mm$(70% of total span, 200 mm). In a modified model, When moving boundary condition(walkway foot loads) is located at ${\times}1$(=0 mm), the location of minimum principal stresses is found at 168 mm( 84% of span, 200 mm), in which the stress concentration due to the foot load is modeled as two layers of distributed loads(reactions of foundation modeled as springs). Consequently, zero deformed reservoirs for rainwater on the neutral axis (${\times}2=167mm$) has been determined in the modified model with three dimensional FEM analysis verifications.

Incontinence is the urination disorder as the leakage of urine without her own volition and the woman's representative disease which reduce the life quality. The electromagnetic therapy has high possibility of development cause it has no needs of operant exercise, no arousing of shame and impossibility of infection. But, it has improvement points such as uniformity of the treatment protocol, patient dependance and absent of patient monitoring system. With these demands, the system which stimulate the pelvic flaw muscle with electromagnetic and monitoring the patient status during the therapy is proposed, in this study. And individually adapted electromagnetic therapy system for incontinence patient is also suggested. The proposed system consisted of electromagnetic generation device, cooling device, treating chair, patient monitoring device with pulsation and control software. The simulation for high power system and evaluation confirm was performed. With the development of control software, the convenience of using and maintenance are ensured and the patient adapted therapy protocol is applied. The developed patient adapted electromagnetic therapy system with monitoring device is regarded as the patient affinitive treating method by reducing the riskiness, improving the efficiency with patterned protocol and pre/post therapy. These results, in this study, can bring the safe and organized treatment method to incontinence patients and can lead the variable study for electromagnetic therapy in incontinence.
