In recent years, frequent terror or military attack by explosion, impact, fire accidents have occurred. Particularly, World Trade Center collapse and US Department of Defense Pentagon attack on Sept. 11 of 2001. Also, nuclear power plant incident on Mar. 11 of 2011. These attacks and incidents were raised public concerns and anxiety of potential terrorist attacks on major infrastructures and structures. Therefore, the extreme loading researches were performed of prestressed concrete (PSC) member, which widely used for nuclear containment vessel and gas tank. In this paper, to evaluate the blast resistance capacity and its protective performance of bi-directional unbonded prestressed concrete member, blast tests were carried out on $1,400{\times}1,000{\times}300mm$ for reinforced concrete (RC), prestressed concrete without rebar (PSC), prestressed concrete with rebar (PSRC) specimens. The applied blast load was generated by the detonation of 55 lbs ANFO explosive charge at 1.0 m standoff distance. The data acquisitions not only included blast waves of incident pressure, reflected pressure, and impulse, but also included displacement, acceleration, and strains at steel, concrete, PS tendon. The results can be used as basic research references for related research areas, which include protective design and blast simulation under blast loading.

우리나라의 서비스 직업에 대한 고용비중이 점차 높아지고 있는 동시에 여성의 경제활동도 함께 증가하는 추세를 보여주고 있다. 또한 현재 경영의 환경에 있어서의 소비자들은 기업과의 직접적인 대면과 함께 우량의 서비스 품질을 요구하는 경영환경의 시대에 있다. 각 기업은 차별화 전략으로서 최상의 서비스 제공을 통한 고객 만족 극대화에 초점을 맞추고 있으며 특히, 서비스 기업에서 추구하는 고객만족 또는 서비스 만족도가 기업의 경쟁우의를 결정짓고 기업의 이미지를 표현하는 중요한 요인으로 여겨지고 있다. 이러한 고객만족을 중시하는 기업과 조직의 목표에 의해 대부분의 고객센터의 여성 근로자들은 조직이 요구하는 감정표현의 규범에 의해 자신의 감정이나 느낌을 고객에게 연출하도록 강요받고 있다. 근로자의 기분과 감정과는 관계없이 고객에게 미소와 친절을 보내야 하는 고객센터 근로자들은 감정노동을 하고 있는 것이다. 이에 본 연구에서는 서비스 산업 중에서도 여성인력에 대한 의존도가 높은 고객만족센터(텔레마케터 or 전화상담원)에 근무하는 여성근로자를 중심으로 감정적 부조화에 따른 감정노동이 직무스트레스에 미치는 영향에 대하여 알아보고 연구 결과를 통해 고객센터의 여성근로자들의 인적자원관리 차원에서 감정노동에 대한 인지와 직무스트레스 조절을 통한 관리에 시사점을 제안하고자 한다.

Although healing is now developing an interest in extending tourism, there have been few studies in this area. Especially late-night tour is closely related to healing experience, but there are little researches that help us understand healing in late-night tour. This study was conducted to examine the relationships among late-night scapes(light aesthetics, sharing mood, culture uniqueness), healing experience(stress reduce and psychological happiness), attitude toward late-night tour. We collected data involving various late-night tourist, and used 198 respondents to analyze these data using LISREL structural modeling. Light aesthetics and sharing mood had positive effects on stress remove, but Culture uniqueness didn't have a signigicant effect on stress remove, unlikely the prediction. And all late-night shape had positive effects on psychological happiness. Also we tested the effects of the healing experience(stress remove and psychological happiness) on attitude. In the final section, we discussed several limitations of our study and suggested directions for future research. We concluded with a discussion of managerial implications, including the potential to advance understanding late-night tourist and implying an enhanced ability to satisfy target consumers of late-night tour.

Job stress of Korean workers is 87.8% which is the highest level among OECD countries(average 80%), and job satisfaction is 69% which is the lowest satisfaction much lower than the average(81) of OECD. This study aims to analyze the effect of LMX; Leader-Member Exchange regarding job stress and job satisfaction empirically. According to the result of the study of employees in special hotels in capital areas and Jeolla province, the difference between job stress and intensity showed partial differences in marital status. In addition, the mediating roles of the LMX quality showed that the only organization-related stress consisting of role conflicts and role ambiguity factors was found to be mediated by the quality of LMX in terms of the effect on job satisfaction. Also, the effect of job authority-related stress and job environment stress on job satisfaction showed that the quality of LMX didn't have an influence.

This research aimed to empirically investigate the effects of satisfaction in Elderly Care Facilities (ECF) and daily stresses of aged people on their depression and self-esteem. Subjects were 271 visitors to 8 ECFs located in Central Korea including Seoul. The data was collected by the survey on them, conducted from March 3 to August 25, 2013. By analyzing the data, we found that the satisfaction with service utilization in ECF can reduce depression, while the satisfaction with medical rehabilitation service may increase depression and that the satisfaction with physical environment can reduce self-esteem. Also, the results showed that the stress related to family relationship has a positive effect on depression and a negative effect on self-esteem. and that the stress concerning residential environment can decrease self-esteem. Depression and self-esteem of the elderly can be predicted by satisfaction in ECFs, but not better than by their daily stresses. Among the predictors of depression and self-esteem, in this study, stress concerning family relationship is the most significant and the strongest.

The high-level nuclear waste (HLW) repository is exposed to complex environmental conditions consisting of high temperature, high humidity, and radiation, resulting in structural deterioration. Therefore, structural health monitoring is essential, and piezo sensors are used to detect cracks and estimate strength. However, since the monitoring sensors installed in the disposal tunnel and disposal container cannot be replaced or removed, the quantitative life of the monitoring sensor and its suitability must be assessed. In this study, the life of a piezo sensor for monitoring was assessed using an accelerated life test (ALT). The failure mode and mechanism of the piezo sensor under high temperature conditions were determined, and temperature stress's influence on the piezo sensor's life was analyzed. ALT was conducted on temperature stress and the relationship between temperature stress and piezo sensor life was suggested. The life of the piezo sensor was assessed using the Weibull probability distribution and the Arrhenius acceleration model. The suggested relationship can be used in multiple stress ALT designs for more precise life assessment.

The purpose of the study was to examine health-related behaviors and nutrient intake in relation to job stress level of police officers. Total of 166 police officers working in Jeonbuk area participated in the study. The study was conducted from February to March, 2009. Subjects were given self-administered questionnaire on their general health status, dietary and health-related habits. Nutrient intake was assessed by semi-quantitative food frequency questionnaire. Subjects were divided into four groups (very low, low, high, very high) by their job stress level scores. Main concerns of job stress were from 'job demand', 'organizational system' and 'lack of reward'. More than 95% of the subjects were confident of their health status. Health habits, such as drinking, smoking and exercising, were better than that of average Korean men. There were significant differences in dietary habits in relation to job stress level. Lower job stress group showed lower rate of skipping breakfast (p<0.01), more affordable meal time (p<0.05) and better snacking habits (p<0.001). Sweet food preference was higher in lower job stress group (p<0.05). The average calorie intake was $2063\pm532.7$ (88.5% of EER) and there was no significant difference in nutrient intake among job stress levels. However, mean intake of calcium and vitamin $B_2$ was less than 75% of %DRI in higher job stress group. Therefore, further support in nutritional counseling programs to improve dietary behaviors and health habits and to reduce job concerned stress of the police officers will be necessary.
