Claims are on an increasing trend in the domestic construction field with changes of negative thought about them. But there are still many factors of causing disputes Potentially due to old customs that an owner is predominant over a contractor. Unless these factors are solved, it is obvious that many disputes will occur henceforward. This study derives claim factors that must be solved first of all through analyzing how claim factors influence construction management factors such as time, cost, quality, and presents countermeasures that may prevent these claims.

According to the domestic construction business will continue stagnant, many domestic construction companies are expanding their business into foreign countries. As results, building design guidelines including HVAC design for foreign countries considering the regional climate conditions are needed. Also, green building design strategies to minimize the heating and cooling load are key issue to win a contract in construction business in the world. In this study, peak heating and cooling loads were calculated for the representative cities in the world : Seoul, St. Petersburg, Singapore and Mecca. The analyzed building was a typical high-rise office building and the building envelope properties, indoor heat gain, residence and operating schedules were same in all cases. Only the weather conditions were different by cases.

Backgrounds: Irregular and unpredictable work schedules have become more common in most societies. The purpose of this study was to investigate the association between unpredictable work schedules and depressive symptoms in Korea. Methods: Data from 34,486 workers who participated in the Korean Working Condition Survey in 2017 were used. Unpredictable work schedules were measured by questions about the frequency of changes in work schedule and limited advanced notice. Depressive symptoms were assessed by a single item asking if the participants had depressive symptoms over the last 12 months. Multivariable-adjusted logistic regression analysis was used to calculate odds ratios (ORs) for high depressive symptoms. Results: The OR for depressive symptoms was significantly higher in the workers with unpredictable work schedules compared to those with predictable work schedules after controlling for age, sex, education, salary, marital status, occupation, contract period, full-time versus part-time, shift work, weekly working hours, and having a child under the age of 18 years (OR = 2.43, 95% confidence interval 1.93-3.07). Conclusion: Unpredictable work schedules were associated with depressive symptoms controlling for the other dimensions of precarious employment in a representative working population in Korea.

The primary objective of the agency research in the game theory lives in the maintenance of Pareto is optimal condition for the optimal incentive contract. The basic concepts which are related to this objective are reviewed in connection with the general assumptions to model it, the moral hazard and adverse selection which arised from the information asymmetry, and finally the problem of risk distribution. The demand for auditing and the role of auditor have been addressed by ASOBAC. Issues which an auditor is explicitly introduced in a principal-agent framework have been addressed in this paper. These issues must be confronted to appropriately with the auditor, and to achieve an adequate understanding of optimal confronting arrangement with the auditor. The first step in introducing an auditor into this analysis is to examine the game-theoretic foundation of such a expended agency model. The Mathematical program formulated may not yield solution that are resonable. This arises because the program may call for the auditor and manager to play dominated Nash equilibra in some subgame. The nontrivial natures of the subgame implies that randomized strategies by the auditor and manager nay be of crucial importance. The possibilities for overcoming the randomized strategy problem were suggested; change the rule of the game and or impose covexity condition. The former seems unjustifiable in on auditing context, and the latter promising but difficult to achieve. The discussion ended with an extension of the revelation principle to the owner manager-auditor game, assuming strategies. An examination of the restriction and improvement direction of the basic concept of agency theory was addressed in the later part of this paper. Many important aspects of auditor incentives are inherently multiple-agent, multiple-period, multiple-objectine, phenomena and require further analyses and researches.

The Korea Seaman's Act is providing that fishermen s salaries are exceptionally defined and working hours and paid leave are not defined at all. Significant problems of Fishermen's Labor Condition are, (1) It is hard to guarantee the basic right of fishermen as their wages are variable depending on the catch. (2) Excessive working hours would hamper the labor reproduction ability and increase the frequency of disaster. (3) Moreover, fishermen have to search for a new job following the lay off after working aboard during the period defined by contract. The possible implement of Seamen's Act are : (1) The wage system must be unified by regular wages. If it is hard to perish the lay system its relative importance should be diminished whereas the fixed minimum wages and the allowance depending on the position and working days should be paid. (2) This discrimination of the fishing vessels from merchant should be eliminated by removing the item on the Act which excludes the fishermen on the working hours. If it is hard to do so practically the lower regulations defining the maximum periods of duty and minimum periods of rest for fishermen must enact separately as in Japan and England. (3) The difference in the provisions of paid leave between the merchant seamen and fishermen must be abolished (4) It is the most desirable to improve the fishermen's labor conditions through the completion of the Act. However, before doing this, the employers and employees must try to solve the problems through the collective agreement by themselves.

Precarious employment is negatively associated with mental health including depression. The aim of the study is to suggest the multidimensional definition of precarious employment and examine its impacts on depression. Using the fifth save of the Korean Working Condition Survey, we first measured six different dimensions of employment precariousness: temporariness, disempowerment, vulnerability, difficulty exercising rights, unpredictability of working times, and low wage. All of six precariousness indicators consisted of a scale from 0 to 100. Then, we conducted logistic regression to examine the association between employment precariousness and depression. For men, the risk of depression increased by 3.1%, 1%, and 0.5%, respectively, for each one point increase in vulnerability, difficulty in exercising rights, and unpredictability of working times. For women, the risk increased by 0.5%, 2.3%, and 0.8%, respectively, for each one point increase in temporariness, vulnerability, and difficulty in exercising rights. Our findings suggest that not only a secure employment contract, but also their substantive labor rights should be guaranteed for health for workers.

1997년 외환위기 이후 국내 부실기업의 해외매각을 빠른 속도로 진행하여 매각과정에서 협상력 부재로 인해 기업가치를 제대로 평가받지 못하였을 뿐만 아니라 계약조건 부분에 있어서도 협상성과는 매우 낮은 것으로 평가되고 있다. 또한, 부실한 계약조건으로 인해 계약이행이 종료되지 못하고 소송이나 중재와 같은 분쟁발생이 급격이 증가하고 있다. 이러한 문제인식 하에 본 논문은 부실기업 매각협상 사례중 국제중재와 관련된 한보철강 매각의 사례를 통해 매각시 국제중재를 통해 분쟁을 해결하는 과정을 상세하게 설명함으로써 향후 매각협상 과정뿐만 아니라 매각이후 분쟁이 실제로 발생한다면 이에 대한 정확한 대처와 중재 대처 전략을 수립할 수 있도록 하기 위함이다. 중재는 소송과 달리 단심제로서 중재기간이 상대적으로 짧다고 볼 수 있으나 단심제의 특성을 감안하여 최대한 유리한 증거와 증인확보 등 보다 더 적극적인 자세로 임해야 할 것이다. 본 사례연구에서 중요한 시사점은 국내 협상자들이 협상시 매각가격에만 중요성을 부여하며 기타 계약조건 특히, 준거법 및 관할권에 대해 소홀히 취급하는 경향이 있다는 점이다. 본 한보 중재에서도 승리의 결정적인 원인은 바로 계약서에 준거법을 한국법이라고 명시하였기 때문에 가능했던 것이다 이러한 점은 향후 국제협상시 중요하게 다루어져야 할 사항이라고 판단된다.

Several epidemiological studies have suggested that residential or occupational exposure to power frequency magnetic fields (MF) might increase the risk of cancer. The objective of this study is to elucidate the possible carcinogenic effects of MF exposure using female Sprague-Dawley (Crj:CD)rats. A total of 360rats was randomly divided into 6 groups of 60 rats each. Two groups were served as a negative control (vehicle: sesame oil only) or a positive control (single oral administration of 7, 12dimethylbenz(a)anthracene; DMBA, 90mg/kg body weight at 50-52days of age). Other four groups were simultaneously exposed to 0 (sham-exposed) 7, 70 or 350 $\mu$T(rms), continuous circularly polarized 50HzMF, 22 hrs/day, 7 days/weeks for 30weeks from 8weeks of age. Experiment was conducted under SPF condition and in a blinded manner, Ten animals in each grout were served as satellite animals and their several hormonal concentrations in sera, such as melatonin and prolactin, collected at the midnight were measured. In addition, complete histopathological examination were performed in other 50 animals per each group. In the positive control group, the first mammary nodule was palpated at the 7th weeks of experiment in 5 out of 59 animals. Afterward, the incidence of palpable mammary nodules increased steadily and reached at 76% and 98% of live animals at 14weeks and the end of experiment in sham and 350$\mu$ T-exposed groups were not significantly different from those in the sham-exposed and negative control groups. Histopathologocally, most of palpable nodules were mammary tumors. The incidences of animals with mammary tumors per animals survived ant the end of experiment were 4.1 and 100% in the negative and positive control groups, and 0.0, 6.0, 8.0 and 6.0% in the sham-, 7, 70and 350 $\mu$T-exposed groups, respectively. These incidences in three MF-exposed groups were not significantly different from those in both the sham- exposed and negative control groups. Based on these results, it was not supported that continuous circularly polarized 50 Hz magnetic fields at up to 350$\mu$T affect the incidence of spontaneous mammary tumors in female SD rats under the present experimental conditions.

The purpose of this study is to review the contents of the legislation(2015.5.12.) for shop key money concretely and to find an effective way in making an improvement of practical protection in the process of tenant's shop key money collection. From this point of view, this study tries to make some legislative suggestions as follows. First of all, the code of conflicting definition between 'shop key money' and 'shop key money contract' in the amended Commercial Building Lease Protection Act need to be harmonized with each other because they are likely to face potential problems in the protection of tenant's shop key money collction as well as risks for confusion. In the second place, it requires to strengthen the protection of tenant's shop key money collection by approval of direct opposing power of shop key money itself on condition that it satisfies a certain prerequisites. In addition, the ambiguous codes related to the landlord's disturbance should be distinctly arranged and the distribution principle of demonstration about landlord's disturbance on tenant's shop key money collection also should be made clear. Finally, the standard level of shop key money by region, business district, and category of business should be set and announced by Ministry of Land and Transport.
