Some groups do ethical activities (such as ethical slogan t-shirt campaigns) only to complete the requirements for ethical duty; consequently, some people question the effectiveness of those products. The attributes of ethical slogan t-shirts should be considered seriously to reduce skepticism when planning a campaign. Researchers can also suggest a new purpose for ethical t-shirts using an ethical message. In study 1, we conduct a conjoint analysis that suggests realistic multi-attribute choice decisions. The suggested multi-attributes wear design aesthetic (high/low), price (high/low), where we donate (close/far), and the size of firm (big/small). In addition, participations were divided into two groups according to eco-friendly attitudes to confirm differences in choices between two groups. Study 1 showed that price is the most important attribute, but design aesthetic also remains important. In addition, a group that has a high eco-friendly attitude thought "where we donate" was more important than other groups. In study 2, a pre-post approach investigated wearers' attitude changes. We also divided participants into two groups and one group wear high level design aesthetic t-shirts (and vice-versa) to measure the attitude change difference. As a result of study 2, the wearers partially changed their eco-friendly attitudes. The group that wore high design aesthetic t-shirts showed a greater difference than other groups. Through this study, we conclude that customers seriously considered the design aesthetic. Finally, wearing ethical slogan t-shirts can change the attitudes of wearers.

In all enterprises of Korea employing workers more than five, employeers have a duty of conducting a periodic health screening for improvement and maintaining healthful living and working conditions of employees. The health screening is performed annually in line workers and biennially in table workers under the supervision of the government. But there are some argument to the health screening programme in view of effectiveness, efficiency, reliability and etc. In order to obtain basic reference materials for increasing the efficiency of peridoic health screening programme for workers and understand the attitude of health screening institutions and enterprises toward the periodic health screening, mail questionnaire survey was conducted in July 1987. The questionnaire sent to 950 health screening institutions. and 700 enterprises in whole land but they were returned from 254 health istitutions and 187 enterprises, which were analyzed. The results were as follows: 1) The attitude of the respondents toward the necessity and benefit of the periodic health screening was showed highly positive responses in both of screening institutions and enterprises, and it was more positive in screening institutions. The attitude toward the affirmative and the contentment was showed less positive than that of the necessity and benefit. 2) The respondent recognized may problems on regard to the screening programme. The health screening institutions lie in the state of competition with other institutions for undertaking the screening programme. 3) One of major complaints from enterprises was the lack of sincerity in performing the screening programme. They wanted more practical and reliable health screening examination rather than showy one. 4) Health screening institutions and enterprises showed some mutual contradictions in the matter of screening fee, and so the screening fee should be adjusted to the appropriate cost.

In this paper, we propose a method to improve cell edge users' performance in HetNet (heterogeneous network) systems by cooperatively transmitting signals using remote radio heads (RRHs) located near coverage boundaries, referred to as edge RRHs. The proposed method locates the edge RRHs in specific locations of the cell boundary and provides an efficient operational strategy by adjusting the duty cycle of the edge RRHs and base stations. The effectiveness of the method is demonstrated by experimental performance based on the system model parameters of the CoMP (coordinated multi-point transmission and reception) scenario, which is discussed in LTE-Advanced (Long Term Evolution - Advanced) standard contributions. When compared with conventional methods, utilization of edge RRHs is especially advantageous for the performance improvement of lower percentile users in terms of average throughput and effectively improves the fairness among users.

There has not been any scientific analysis on appropriate size of workforce and salary for civilian workers in military so far. Thus, this paper conducted analysis on propriety in employment size of military doctrine researchers using system dynamic methodology based on annual military doctrine workload. Vensim software was mainly used to measure complement of the research group based on data from job analysis. Secondly, a multiple regression analysis was performed to study an appropriate wage for researchers based on their expertise and working condition. The data from twenty public research institutions and twenty eight job positions that are performing similar duty with military doctrine researchers was obtained and utilized to create a salary-estimation regression equation in the analysis. Finally, with cost-benefit analysis method this paper studied financial effectiveness of hiring military doctrine researchers. Contingent valuation method, which has been recognized as one of the most effective methodologies in cost-benefit analysis on intangible value, was utilized to measure benefit of hiring the researchers. The methodology presented in this paper can be applied to measure and improve the efficiency of military organization not only in military doctrine research area but also in several military functional area (military training, logistics, administration, combat development, and combat support).

Judging from the past cases, the contractor has frequently suffered losses caused by disapproved requests or reduced payments since it has not known the conditions of the contract or it has filed a claim to the owner without any proper claim system. Therefore, the existing claim process needs to be reformed. In order to reform the claim process, the contractor should consolidate the organizational structure, grant accurate duty assignments to the claims manager, implement regular staff training on how to deal with claims. In addition to this reformation, the contractor needs to improve the management of construction period and process control, and manage related documents thoroughly. Regular meetings are also necessary in claims. This study attempts to prove the effectiveness of the reformed process applied to Project "A", where the owner was responsible for the delayed supply of materials, inaccurate oral instructions, insufficient information on the work, and frequent changes of design. The project was completed in 96 months, which was extended by 34 months from the initial construction period of 62 months. The reformed claim process is expected to be of great help not only to largescale construction works but also to smallscale ones.

This paper presents a new circuit topology of active edge resonant snubbers assisted half-bridge soft switching PWM inverter type DC-DC high power converter for DC bus feeding power plants. The proposed DC-DC power converter is composed of a typical voltage source-fed half-bridge high frequency PWM inverter with a high frequency planar transformer link in addition to input DC busline side power semiconductor switching devices for PWM control scheme and parallel capacitive lossless snubbers. The operating principle of the new DC-DC converter treated here is described by using switching mode equivalent circuits, together with its unique features. All the active power switches in the half-bridge arms and input DC buslines can achieve ZCS turn-on and ZVS turn-off commutation transitions. The total turn-off switching losses of the power switches can be significantly reduced. As a result, a high switching frequency IGBTs can be actually selected in the frequency range of 60 kHz under the principle of soft switching. The performance evaluations of the experimental setup are illustrated practically. The effectiveness of this new converter topology is proved for such low voltage and large current DC-DC power supplies as DC bus feeding from a practical point of view.

To ensure the safety for vessels anchored in stormy weather, duty officer and VTS operator have to frequently check whether their anchors are dragging. To judge dragging of the anchored vessel, it is important for VTS operator to recognize the turning circle and its center of the anchored vessel. The judgement for the anchored vessel dragging can be made by using Radar and AIS. If it is available, CCTV or eye-sighting can be used to know the center of turing circle. However, the VTS system collects individual ship's dynamic information from AIS and ARPA radar and monitors of the anchored vessels, it is difficult for VTS operator not only to get the detailed status information of the vessels, but also to know the center of turning circle. In this study, we propose an efficient algorithm to estimate the center of turning circle of anchored vessel by using the ship's heading and position data, which were from AIS. To verify the effectiveness of the proposed algorithm, the experimental study was made for the anchored vessel under real environments.

Purpose: The aim of this study was to examine effectiveness of 12-hour shifts for nurses compared to 8-hour shifts for the variables: Work-Life Balance, fatigue and work errors. Methods: In 2014, an opportunity to choose a 12-hour shift duty was given to a group of 8-hour shift nurses. In 2016, two years after this change, this study was done to compare the two groups. Data were collected using questionnaires. Data were sampled by a matching method with propensity score matching (PSM). The participants were 128 nurses: 64 nurses on 12-hour shifts and 64 nurses on 8-hour shifts. The comparison was analyzed using $x^2$ test, t-test. Results: The nurses on 12-hour shifts showed higher scores for Work-Life Balance (3.37) than the groups on 8-hour shifts (2.99)(p=.018) whereas were no statistical differences between the groups for fatigue (p=.132) or work errors (p=.703). Conclusion: The Work-Life Balance scores for nurses who chose the 12-hour shift shows an enhancement without an increase in fatigue or work errors.
