Recently, many korean construction companies have faced many environmental changes and demands for external changes. This demand for external changes is necessary for all companies that is under the survival of fittest. The internal/external of environmental changes affect the organizations of company largely, and these management organizations have relation with the corporate of management performance closely. In response to that, to be adapted to the environmental change and to raise the corporate of management performance, the construction companies have tried to change the organizations such as organization re-design, organization re-build, organization innovation. Because the organizational structure that is preventive in the growth of companies bring a negative effect, the companies need to have the effective organizations to raise the corporate value. The effective organizations could be used the important indicator that builds the corporate goals and manages the organizations. Also, the organization development and organization management can prepare for environmental changes can be the important base to increase the management performance. Therefore, After surveying and analyzing the character of organization structure in respect to the OLC, this study present the Organization Structure Model that can design the appropriate organization by the growth of companies.

The collaboration that seeks to complement each other by judging and sharing the comparative advantages between companies is currently being actively progressed as a new and unusual collaboration that is not routine among not only the same industry but also different industries. This trend is increasing consumer interest based on enjoyment and fun. However, these collaborations cannot consistently lead to positive effects, and rather, if all companies collaborate, it could have an adverse effect. The current study explored the consumer's response to the attitude toward product and purchase intention of collaboration through consumption value and brand trust based on the consumer's understanding, assuming that the consumer's response cannot always be positive. As a result, brand trust played a mediating role in the intention to purchase and attitude toward product. This study examines the relationship between consumption value and collaboration products between brands, and from the perspective of a company, it can provide practical implications for establishing brand management and strategy through a unique collaboration strategy based on the understanding of consumers.

As more migrants stay for a longer term or settle in Korea through marriage, labor contract, defeat of North Korea, etc, the discourse on the migration policies gets more complicated and expands further beyond the issue of their adaptation to the Korean culture and their rights to encompass their families and children. The social integration policies for children of migrant families in Korea have been mainly led by the Ministry of Gender Equality and Family and Ministry of Education, Science and Technology. This paper will look at the challenges that children with migrant background face and their problems while reviewing the policies on children with migrant background in a critical perspective. In conclusion, it gives some suggestions to help establish more open society with multi-cultural values espoused.

Purpose: We aimed to examine the effects of an integrated physical activity (PA) program developed for physically inactive workers on the theoretical basis of the PRECEDE-PROCEED model. Methods: Participants were 268 workers in three departments of L manufacturing unit in South Korea. The three departments were randomly allocated into integration (n=86) (INT), education (n=94) (ED), and control (n=88) (CT) groups. The INT group received self-regulation, support, and policy-environmental strategies of a 12-week integrated PA program, the ED group received self-regulation strategies only, and the CT group did not receive any strategies. After 12 weeks, process evaluation was conducted by using the measures of self-regulation (autonomous vs. controlled regulation), autonomy support, and resource availability; impact evaluation by using PA measures of sitting time, PA expenditure, and compliance; and outcome evaluation by using the measures of cardiometabolic/musculoskeletal health and presenteeism. Results: Among process measures, autonomous regulation did not differ by group, but significantly decreased in the CT group (p=.006). Among impact measures, PA compliance significantly increased in the INT group compared to the CT group (p=.003). Among outcome measures, the changes in cardiometabolic/musculoskeletal health and presenteeism did not differ by group; however, systolic blood pressure (p=.012) and a presenteeism variable (p=.041) significantly decreased only in the INT group. Conclusion: The integrated PA program may have a significant effect on increases in PA compliance and significant tendencies toward improvements in a part of cardiometabolic health and presenteeism for physically inactive workers. Therefore, occupational health nurses may modify and use it as a workplace PA program.

현재 급변하는 정보기술, 다양성을 추구하는 시장의 니즈, 미리 예측하지 못한 다양한 형태의 경쟁자 등의 출현으로 인해 경영환경이 급변하고 있는 것은 더 이상 새로운 현상이라고 보기는 어렵다. 이와 같이 급변하는 경영 환경은 기업 간 경쟁 심화를 불러일으키고 있으며, 경쟁 심화는 생존 및 발전을 위해 기업 특성에 맞지 않는 무분별한 전략을 활용하면서 오히려 역효과를 내고 있다는 문제를 야기하고 있다. 특히 변화하고 있는 환경 내 벤처기업 및 창업기업들의 경우 창업 후 생존율이 점차 낮아지면서 일반 기업들에 비해 경쟁력을 갖춘 기업을 찾아보기 어려운 것이 현실이다. 이에 벤처기업들은 도태되지 않고 생존하기 위해경쟁력을 강화시킬 수 있는 다양한 전략을 구사하고 있다. 벤처기업은 하나의 비즈니스 생태계 내 유기적 생명체로서 진화하기 위해 제품이나 산업의 수명주기와 마찬가지로 창업기, 초기 성장기, 고도 성장기, 성숙기, 쇠퇴기 등의 정형화된 단계를 거친다. 따라서 벤처기업은 무차별적인 전략을 통해 기업의 생존 및 성장을 도모 하는 것이 아니라 해당 기업이 놓인 수명주기 단계별로 전략, 조직 구조, 의사결정방식, 통제유형 등을 상이하게 판단하고 이에 적절한 전략을 수행해야 한다. 예를 들어, 동일 생산요소를 투입하더라도 이를 적용할 수 있는 지식이 있는 경우 더 높은 가치 창출이 가능(Aghion & Howitt, 1992) 하지만 창업 초창기의 기업은 고도 성장기의 기업보다 보유한 지식 수준 및 경험이 상대적으로 낮기 때문에 다양한 협력을 필요로 한다. 그러나 현재의 여러 선행연구들은 기업이 처한 상황을 고려하지 않은 단편적인 대처 방안이거나 혹은 부분적인 방법론을 제공하는 수준에 그치고 있다는 한계가 있다(이병헌 외, 2014). 따라서 본 연구에서는 '2016년 벤처기업정밀실태조사' 데이터를 기반으로 기업의 외부 협력 정도 및 벤처기업 지원제도 활용 정도가 경쟁력과 성과에 미치는 영향이 기업의 수명주기별로 상이하다고 보고 관련 전략 프레임워크를 제시하고자 한다.

The movie <Yin Ru Chen Yan> is evaluated to reflect the rural reality of China's northwest region. Although the film also contained the farmer's unique sincerity and pure love, many problems were also raised. The specific issues raised are as follows. First, he accused young Chinese rural people who could not express their intention properly at the time of marriage.This can be said to be largely due to the lack of proper education, medical care, and welfare benefits for a long time. Second, he criticized the rural housing policy that deviated from reality. It warns that unilaterally providing apartments in the city without considering regional characteristics and farmers' situations could be counterproductive. In the movie, the main character abandoned livestock that he thought of and cared for with his family and did not move his residence to an apartment. Third, he criticized the materialism prevalent in rural areas. He criticized the phenomenon of not respecting a human being to solve everything with money and even to receive government housing compensation. In this sense, in order to solve the true Chinese Samnong problem, macro-promoted policies and micro-policies that can encompass some underdeveloped rural areas should also be implemented.

This study applies the concepts of sociotechnical theory and role theory in order to verify the effects of stress (that is, technostress) created from information and computer technology (ICT) concerning role stress and performance. We suggest diverse perspectives concerning the elements leading to technostress along with the stress-creating process of ICT among organizational members. The following four major hypotheses are proposed: (1) Technostress is positively related to role stress (e.g., conflict and overload of roles), adverse psychological outcomes, and adverse IS use related outcomes, (2) Role conflict is positively related to adverse psychological outcomes and adverse IS use related outcomes, (3) Role overload is positively related to adverse psychological outcomes and adverse IS use related outcomes, and (4) Innovation support will play as a moderator between technostress, roles tress, adverse psychological outcomes and adverse IS use related outcomes. A partial least square (PLS) with data gathered data from ICT users of organizations was used to verify the proposed hypotheses. The results supported our claims excluding the hypothesis associated to the relationship between technostress and role stress. We suggest a theoretical implication based on the verification of technostress related to the current concept of stress experienced by individuals within organizations. We also propose that a practical implication concerning the opposite effect of technostress, can be utilized as a method of reducing role stress, and suggests a diagnostic tool for assessing the degree of technostress within organizations.

Technological innovations and fast-growing new internet businesses are changing the paradigm of traditional business management, having various impacts on society. The development of internet technology is also increasing the adverse effects on technological innovation, and in particular, cybercrime related to computers continues to increase with each technological innovation. The purpose of this study is to construct a cybercrime business model (CBM) by using the business model canvas (BMC) theory for cybercrime in order to reduce cybercrime, and this model is applied and analyzed based on types of Korean cybercrimes. For this study, a systematic literature review was conducted to determine the components of cybercrime, and 60 relevant documents were classified through a keyword-based literature search. Besides, qualitative research in the classified literature has led to the derivation of cybercrime into 18 sub-blocks and nine building blocks. This study applies BMC theory to this derivation of cybercrime and builds the CBM through proper redefinition. Lastly, the developed CBM could be applied to cybercrime in Korea to help cyber incident-response staff understand cybercrimes analytically. This study contributes to the development of a new analysis framework that can reduce cybercrime.

Cyclodextrin glucanotransferase (CGTase) of Bacillus sp. isolated from soil was purified and its enzymological characteristics were investigated. It was found that the production of CGTase reached to the maximum when the strain was cultured in the broth containing 0.1 % albumin, 2% $NH_4Cl$, 2% soluble starch and 0.2% $NH_2PO_4$ for 72 hrs at $37^{\circ}C$. The purity of CGTase was increased by 9.7 folds through purification procedures by the following column chromatography DEAE-cellulose ion exchange chromatography and Sephadex G-100, G-150 gel filtration and its specific activity was 528.0 unit/mg. The optimum pH and temperature for the CGTase activity were 8.0 and $80^{\circ}C$, respectively. The enzyme was stable in pH $8.0{\sim}11.0$ at $60{\sim}80^{\circ}C$. The activity of purified enzyme was inhibited by $Pb^{2+},\;Hg^{2+}$ and $Zn^{2+}$. When CGTase was treated with each 20.5 unit, 41 unit, 205 unit and 410 unit to investigate the transglucosylation to stevioside by purified cyclodextrin glucanotransferase, transglucosylation rate to stevioside was 74.9%, 75.7%, 68.7% and 57.9%. Brown effect was observed above the concentration amounting to 205 unit of our CGTase.
