The purpose of this study is to examine the effects of job stress on Organizational commitment and turnover intent with targets of Employees of Security Industry. A total of 156 answered questionnaires were used as final data. The following conclusions were obtained by conducting correlation analysis and multiple regression analysis using SPSS 18.0 statistical program. First, it is found that Organizational commitment effects some sub-factors of job stress such as inappropriate compensation, insufficient job control and job requirements. Second, it is found that turnover intent affects some sub-factors of job stress such as inappropriate compensation, insufficient job control and job requirements. Third, it is found that turnover intent affects Organizational commitment. Based on the result of the research, job stress seems to affect organizational commitment and people's decisions to change jobs. The two variables job stress and organizational commitment act as key factors in deciding whether to change jobs, while organizational commitment plays as an important parameter. In other words, there should be principles to do work along with channels through which workers communicate with each other. To this end, there need to be programs educating people to work together as well as systematic assistance and support to encourage people to develop their expertise.

As a forming method for curved hull plates more efficient than the flame bending, mechanical bending using multi point press forming and die-less forming is discussed in this paper. the mechanical forming is a flexible manufacturing system for automatically forming of hull parts. It is especially suited to varied curved parts. This paper discusses a multiple point pressing machine composed of a pair of reconfigurable punches in order to achieve the rapid forming of curved hull plates using division forming and presents how forming information is obtained from the given design surface. Although the mechanical forming can be efficient in the metal forming, spring back after pressing is a phenomenon which must be carefully considered when quantifying the process variables. If the spring back is not accurately controlled, the fabricated shell plate cannot meet assembly tolerance. This paper describes the principles to calculate the proper stroke of each punch at the divided areas. the strokes are determined by an iterative process of sequential pressing and spring back compensation from an unfolded flat shape to its given design surface. FEA(finite element analysis) is used to simulate the spring back of the plate and the IDA(iterative displacement adjustment) method adjusts the offset of pressing punches from the deformation results and the design surface. The shape deviations of two surfaces due to spring back are compensated by integrated system using FEA and IDA method. For the practical application, It is aimed to develop an integrated system that can automatically perform the compensation process and calculate strokes of punches of the double sides' reconfigurable multiple-press machine and some experimental results obtained with mechanical bending are presented.

The Korea Stewardship Code 'Principles on the Fiduciary Responsibilities of Institutional Investors' was introduced in 2016 and the National Pension Service adopted it in 2018. the National Pension Service casted 'dessent' vote on the agenda which is able to reduce the ownership interest of shareholder in general meeting. This paper examines whether 'dissent' voting affected on the ownership interest of shareholder or not. The 'dissent' vote on the agenda are related to revision artical of corperation, appointment or compensation of director and auditor, approval of financial statements ect. The proxies of earnings management is discretionary accruals calculated by modified Jones model. The control variablies are size of assets, liabilities per assets, returns on assets. The results of this study are as followings. First, the 'dissent' voting on the agenda are related to revision artical of corperation, M&A, approval of financial statements ect. are not significant because their sample size is too small, Second, the 'dissent' voting on appointment of director and auditor affected on reduction of discretionary accruals. So the National Pension Service activism shall affect on increasing the ownership interest of shareholder. Third, the 'dissent' voting on compensation of director and auditor is not affected on reduction of discretionary accruals. This results show that 'unconditional dissent voting' on the agenda in general meeting is not to reduce the ownership interest of shareholder.

A launching State shall be absolutely liable to pay compensation for damage caused by its space object on the surface of the earth or to aircraft in flight. The compensation which the launching State shall be liable to pay for damage under "the Convention on International Liability for Damage caused by Space Objects" shall be determined in accordance with international law and the principles of justice and equity, in order to provide such reparation in respect of the damage as will restore the person, natural or juridical, State or international organisation on whose behalf the claim is presented to the condition which would have existed if the damage had not occurred. In the event of damage being caused elsewhere than on the surface of the earth to a space object of one launching State or to persons or property on board such a space object by a space object of another launching State, and of damage thereby being caused to a third State or to its natural or juridical persons, the first two States shall be jointly and severally liable to the third State, to the extent indicated by the following: If the damage has been caused to the third State on the surface of the earth or to aircraft in flight, their liability to the third State shall be absolute; If the damage has been caused to a space object of the third State or to persons or property on board that space object elsewhere than on the surface of the earth, their liability to the third State shall be based on the fault of either of the first two States or on the fault of persons for whom either is responsible. The Insurance requirements are satisfied for a launch or return authorised by a launch permit if the holder of the permit or authorisation is insured against any liability that the holder might incur to pay compensation for any damage to third parties that the launch or return causes; and the Commonwealth is insured against any liability that Commonwealth might incur, under the Liability Convention or otherwise under international law, to pay compensation for such damage. The liability for Damage caused by Space Objects should be regulated in detail in Korea.

This research outlined the factors influencing the business management success via analyzing a survey of business principles. The research process has been tested in comparison of both financial factors, which come out of objective data and non-financial factors so relevantly prioritized by combining these factors. In order to specify the factors, a check-list and analyzed essential features of category have done with interviews and surveys. As consequently proceeding, the authors could deduce that non-financial but analytic factors such as business doable, technician workability, compensation and benefits etc. play major roles in construction sector. The outcomes consider a construction business as fundamental human labor job as opposed to a manufacture business. On reasoning necessarily more objective research works to be done as developing this research's outcome, it is meaningful in suggesting the pivotal factors influencing the construction business management. Therefore, this research is expected to guide the direction to induce the improvement of business management to be done by further exemplary researches.

During the last few decades, fluid viscous dampers have been significantly improved in terms of performance and reliability. Viscous dampers dissipate the input energy into heat and the increased temperature may damage internal seals of the damper. As a result, thermal compensation is crucial for almost all fluid viscous dampers. In this study, while referring to the main working principles of the recently developed bypass viscous damper in Iran, a comprehensive case study is conducted on a RC building having diagonal braces equipped with such viscous dampers. Experimental results of a small-scale bypass viscous damper is presented and it is shown that the currently available simplified Maxwell models can simulate behavior of the bypass viscous damper with good accuracy. Using a case study, contribution of bypass viscous dampers to seismic behavior of structural and non-structural elements are investigated. A designed procedure is adopted to increase damping ratio of the building from 3% to 15%. In this way, reductions of 25% and 13% in the required concrete and steel rebar materials have been achieved. From nonlinear time history analyses, it is observed that bypass viscous dampers can greatly improve seismic behavior of structural elements and non-structural elements.

The Warsaw Convention for the Unification of Certain Rules Relating to International Carriage by Air was adopted in 1929. In 1999, the ICAO adopted the Montreal Convention for the Unification of Certain Rules for International Carriage by Air vastly modernizing the unification of private air law. The Montreal Convention replaced the instruments of the Warsaw system, and came into force on 4 November 2003. The Montreal Convention is not only an international convention. It has also exercised a considerable influence on national legislation. Korea has made the national legislation of the Part VI the Carriage by Air of Commercial Act on April 29, 2011, and it has brought into force on November 24, 2011. The national legislation of the Part VI the Carriage by Air of Commercial Act of Korea has the provisions on the liability for damage caused to passenger, the liability for damage caused to baggage, and the liability for damage caused to cargo. The main feature of the liability regime of the air carrier under the Montreal Convention is the two-tier liability system for death or injury of the passenger with strict liability up to 100,000 SDR and presumptive liability with a reversed burden of proof without any limit above that threshold. The national legislation of the Part VI the Carriage by Air of the Commercial Act of Korea has adopted the main principles of the liability of the air carrier under the Montreal Convention. In conclusion, the national legislation relating to the liability of the air carrier by the Korean government will contribute to settle efficiently the dispute on the carrier' liability in respect of the carriage of passengers, baggage and cargo by air, and to provide proper compensation to the passenger or consignor who has suffered damage, subject to the defenses and limitations it sets out.

The Montreal Convention which came into force on November 4, 2003 over the world, has brought a fundamental change to the scope of carrier liability and expanded the sue scope of the carrier. Not only confirms the carrier liability, it also reflects the effects of code-share. In addition to integrate the existing principles that adopted by many conventions, the Montreal Convention has systematized the unity of international air transport into a single convention. It even successfully increased the extremely low compensation amount which was pointed out as a problem in the Warsaw Convention before. The Warsaw Convention, originally stood for the carriers, began to reflect the standpoint of the passengers. The Chinese Civil Aviation Law came into force on March 1, 1996. One of the significant characteristics of the law is that, the regulation on public and private law is mixed combined. Therein, the content of carrier liability system is prescribed in Chapter 9, which is explained in detail in this study. Besides, the relationship between the Montreal Convention and China will be expounded too. So far, China ranks the 5th in RPK and the 6thin FrK. However, in spite of the high ranks, China has not yet joined this convention. This can be regarded as a serious problem. China should join it as soon as possible for a further development and deeper cooperation with the air-industry-developed countries. Once the government ratifies the Montreal Convention, it will benefit both the Chinese passengers and the airlines.

In atherosclerosis, blood vessels become sensitive to vessel-constricting agents leading to reduced control in the event of abrupt blood pressure changes. Mulberry trees (Morus alba L., MA) have been claimed to contain various bioactive principles that could possibly prevent atherosclerosis development caused by high cholesterol consumption. In order to examine whether MA feeding can prevent the sensitization of blood vessels, MA leaves were fed to rats for 8 weeks and pressor responses to vasoconstricting agents were assessed. Animals were pithed before blood pressure assessments to eliminate reflex compensation in vessel responses. Feeding diets containing high levels of cholesterol led to potentiated pressor responses to sympathetic nerve stimulation, or to injection of norepinephrine, phenylephrine, angiotensin II and vasopressin in pithed rats. These potentiated pressor responses were prevented in rats fed MA leaf-containing diets at 2 or 10% levels. It was also examined in anesthetized non-pithed rats whether similar cholestrol-related sensitization and MA prevention could be observed. However, high cholesterol-induced sensitization in pressor responses were not observed, suggesting that destruction of central cardiovascular control by pithing must have revealed the sensitization responses. It was concluded that MA leaves seem to be active in preventing abnormal blood vessel reactivity caused by hypercholesterolemia.

Under the Korean case law, physicians are obliged to disclose or inform the risk associated with a specific treatment to their patients before they perform the treatment. If they fail to do this, they are liable to compensate pain and sufferings. If the patient can establish that he or she would not have consented at all to the treatment had he or she been informed, the physicians are liable to compensate all the loss incurred by the treatment. In this article, the author examines the legitimacy of this case law from the perspective of legal doctrine as well as its practical affect on the medical practice and the furtherance of self-determination of the patient. The fundamental findings are as follows: The case law that has physicians who failed to inform treatment risk compensate pain and sufferings for the infringement of the right of self-determination seems to be a disguised and reduced compensation of all the loss based on the possible malpractice, which cannot be justified in view of the general principles of tort liability. It is necessary to adhere to the requirements of causation and imputation between the failure to inform treatment risk and the specific patient's consent to the treatment. If this causation and imputation is established, all the loss should be compensated. Otherwise, there shall be no liability. The so-called hypothetical consent defence shall be regarded as a part of causation between the failure to inform and the consent. The suggested approach can preserve the essence of physician-patient relationship and fit for the very logic of informed consent better.
