This paper proposes an opportunistic age replacement policy. The system has two types of failures. Type I failures (minor failures) are removed by minimal repairs, whereas type II failures are removed by replacements. Type I and type II failures are age-dependent. A system is replaced at type II failure (catastrophic failure) or at the opportunity after age T, whichever occurs first. The cost of the minimal repair of the system at age z depends on the random part C(z) and the deterministic part c(z). The opportunity arises according to a Poisson process, independent of failures of the component. The expected cost rate is obtained. The optimal $T^{\ast}$ which would minimize the cost rate is discussed. Various special cases are considered. Finally, a numerical example is given.

This paper presents a new integer formulation (Type III ALB) for a single model assembly line balancing problem. The objective of the formulation is to minimize the total idle time, which is defined as the product of the number of work stations and the cycle times minus the total work content. This formulation considers currently existing Type I (minimizing the number of work stations for a given cycle time) and type II (minimizing the cycle time for a given number of work stations) formulations as its special cases and provides the global minimum solutions of the cycle time and the number of work stations. This information would be of great value to line designers involved in designing new assembly lines and rebalancing old lines under flexible conditions. Solution methods based on combination of Type I and Type II approaches are also suggested and compared.

According to the labor related data from Korea Occupational Safety & Health Agency, accident victims of construction industry are increasing 6% annually since 2006. The major reason why the rate of accidents increases in Korea is that lots of labor working with another trades works simultaneously in various type of works. This study analyzes the current accident status in view of the type of building, type of works, and project size for the latest 3 years (2007~2009). As a result, 'single family & semi-detached houses' has the largest number of accidents among buildings. In addition, 'finishing work' shows the highest number in terms of work type. For the size, accidents occurred much for 'less than 300 million'. The results of this study can be used to focus on managing the highly hazardous area where the construction accidents mostly occur; therefore, it is anticipated to contribute to improve efficiency of safety management.

Fishing trend and characteristics of Korean tuna purse seine fishery in the Pacific Ocean were investigated using logbook data compiled from captain onboard and the statistical data from 1980 to 2013. The historical catch of this fishery had sharply increased since mid-1980s, and it has shown fluctuations with about 2-3 hundred thousands, whereas the catch per number of vessel has steadily increased with fluctuations since commencing this fishery. As for the proportion of catch by set type, unassociated type had increased from the mid-1980s to the end of 1990s, and then has decreased up to 2010s. Associated type had decreased continually to the end of 1990s, however, it started to increase since the beginning of 2000s. As for the catch proportion of set type by main species, those of skipjack tuna and bigeye tuna showed higher in the associated type, whereas that of yellowfin tuna has the highest proportion in the unassociated type. Fishing distribution of Korean tuna purse seine fishery was concentrated on the area of $5^{\circ}N{\sim}10^{\circ}S$ and $140^{\circ}E{\sim}180^{\circ}$ through the decades. The monthly catch distribution by longitudinal zone of Korean tuna purse seine fishery expanded the most further to the eastward in September to October.

The objective of this study was to investigate the effect of the perceived importance of kitchen equipment and facilities on the hygienic performance of cooks in deluxe hotels. Cooks and chefs at 7 different deluxe hotels participated in this study. Out of 490 questionnaires administered, 456 (93.1%) were completed and 419 (91.9%) were analyzed using a statistical package SPSS 12.0. The results were as follows. First, the correlation between sanitary equipment, including HACCP system, in the hotel kitchens and the hygienic management performance confirmed the significant effect of the sanitary equipment on the performance of the cooks and chefs. Second, the sanitary facilities in the hotel kitchens greatly affected the hygienic management performance. The results also demonstrated that the sanitary equipment provided the same contribution to the performance irrespective of the job level, management type and HACCP practice. However, the sanitary facilities greatly affected the management type expecially the chain hotels. The hygienic management performance did not affect the cooking stage (before-cooking and during-cooking), but affected the after-cooking stage according to the management type and the HACCP practice, but not the job level.

Objectives This study aimed to analyze the influence of various sleep-related factors that affect sleep quality by each Sasang type. Methods A total of 400 subjects were included for this study, 108 males and 292 females. Sasang type was diagnosed using the SCAT. Then, the characteristics of each Sasang type were analyzed using HRV, DITI, and PSQI, PSS, and SDFI questionnaires. Logistic regression analysis was used to predict sleep-related factors that affect sleep disorders by Sasang types. Results This study shows that the pathophysiological characteristics for stress and digestive function of each Sasang type can differentiate sleep management through a logistic regression model including subscales of PSS and SDFI. Stress had no effect on the occurrence of sleep disturbance within only So-Eum, since the stress level is originally high in the So-Eum regardless of sleep quality. Rather, decreased appetite and poor eating habits had a significant impact on the decline in sleep quality. In addition, poor digestion and eating habits in So-Yang had a greater impact and poor digestion in Tae-Eum had a greater impact on the decline in sleep quality. Conclusion The stress and subscales of digestive function provide differentiated sleep management in So-Yang, Tae-Eum, and So-Eum types. The individualized sleep management for each Sasang type with statistically validated PSS and SDFI would be useful for sleep-related experts planning safe and effective person-centered health care as well as for Western clinicians who want to incorporate Sasang typology into their treatments as integrative medical technique in the future.

The purpose of this study is to examine the differences in appearance management behaviors and demographic variables among groups classified by the appearance management motives. The questionaries are administerd to 493 female and male adults above 20 years old in Seoul, Kyeonggi-do, Daegu and Kyungpook regions. For analysis of data from 478 respondents, descriptive statistics, factor analysis, cluster analysis, Cronbach's ${\alpha}$, ANOVA, Duncan test and ${\chi}^2$ test were applied. We show the following results: First, factor analysis for appearance management motives extracted three factors such as self-development, emphasis on the trendy appearance, and sexual appealing motive. Factor analysis for appearance management behaviors extracted four factors such as weight training, surgery/skin care, hair care and clothing selection. Second, three groups of the appearance management motives were classified into such as the social self-management type, the sexual appealing self-management type, the passive appearance management type. The social self-management groups are more interested in self-development, emphasis on the trendy appearance, and sexual appealing motive. And they are also more involved in appearance management behaviors: clothing selection is the most pursuing appearance management behavior. Third, among the demographic variables, the single and female in 20s and 30s with higher level of education belonged to the social self-management group. In this contribution, we find significant differences in the appearance management behavior and demographic variables classified by the appearance management motives.
