By measuring concrete temperature and strains of concrete and reinforcing bars throughout gages embedded and also by observing the crack occurrence, this study aims at the characteristics of structural behavior of subway wall structure in associate with concrete ages. The length of 23.5m, thickness of 2.0m of real subway custody line was selected as a representative structure and 7 thermocouples and 6 strain gages were installed to measure the behavior of wall structure. The results were compared and verified with analytical results using MIDAS in order to show their usefulness. It was found that only attachment of strain gages on the surface of reinforcing bars can figure out the timing of crack occurrence and hydration heat program is useful to estimate comparatively exact magnitudes of temperature. Since estimated time of crack occurrence throughout thermal stress analysis depends on the period of transferred thermal stress from concrete to reinforcing bars, however, cracks from naked eyes were identified later than analytical results. Cracks were observed first at the center of wall line and then to the end of line symmetrically.

With the effectuation of Kyoto Protocol, one of the important movement throughout the world is reducing the emission of greenhouse gas which is the main reason of making global warming. The actual factor of greenhouse gas is CO2, and in year of 2002 20% of total CO2 emission was produced only through transportation throughout the South Korea. In the contrary, the recycling of municipal wastes in South Korea was 44.0% in 2002, but it will be targeted upto 53.5% in 2011. All of these show environment-conscious logistics should be implemented together throughout the each stage of distribution with the development of product and service. This study applied survey research for the activities affecting to the emission of CO2 and packaging wastes produced from transportation and packaging stages in logistics area. For this, survey questionary was constructed with five specific areas - strategy, transportation & distribution, custody, packaging, and information. Based on the 148 returned survey questionaries, this study analyzed 52 categories and finally suggests necessary modal shift, collaboration & co-operation in logistics, LCA(life-cycle assessment), and other promoting policies for the environment-conscious logistics in effective way.

Recently, several ICT-based cat studies have produced some successful results, according to academic and industry sources. However, research on the level of simply identifying the cat's condition, such as the behavior and sound classification of cats based on images and sound signals, has yet to be found. In this paper, based on the veterinary scientific knowledge of cats, a practical and academic cat monitoring and disease diagnosis system is proposed to monitor the health status of the cat 24 hours a day by automatically categorizing and analyzing the behavior of the cat with location information using LSTM with a beacon sensor and a raspberry pie that can be built at low cost. Validity of the proposed system is verified through experimentation with cats in actual custody (the accuracy of the cat behavior classification and location identification was 96.3% and 92.7% on average, respectively). Furthermore, a rule-based disease analysis system based on the veterinary knowledge was designed and implemented so that owners can check whether or not the cats have diseases at home (or can be used as an auxiliary tool for diagnosis by a pet veterinarian).

Law enforcement officers (LEOs) often encounter rapidly changing and uncontrolled situations that expose them to various hazards. A law enforcement agency requested an evaluation by the National Institute for Occupational Safety and Health (NIOSH) when multiple LEOs reported illness after executing a search warrant and taking a suspect into custody. NIOSH investigators interviewed LEOs and reviewed medical records, forensic laboratory results for collected evidence, and environmental testing results of samples taken after the operation. Two-thirds (25 of 38) of LEOs who participated in the operation reported ≥1 symptom. Eleven LEOs met a case definition for influenza-like illness (ILI). Members of one unit were more likely to have ILI than non-members (prevalence ratio (PR), 4.1; 95% confidence interval (CI): 1.3-13.0; p = 0.01). Influenza vaccination was associated with a lower prevalence of ILI (PR, 0.2; 95% CI, 0.1-0.9; p = 0.02). Preventing employees from working while ill and annual influenza vaccination might prevent similar occurrences.

Purpose: This study investigated the health and socioeconomic status of single-parent and partnered families, and examined the intersection between sex and single-parent status focusing on inequalities of health and socioeconomic status. Methods: This was a cross-sectional study using the data from the nationally representative 2005 Korean National Health and Nutrition Examination Survey. A total of 14,827 respondents had custody of their own children and other family members (13,943 were coupled families and 891 were single-parent). Results: Our result indicate that single-parent had poorer health status and were more likely to have lower educational attainment, lower household income, no home ownership and be unemployed. However, the association between single-parent status and socioeconomic and health inequality were in divergent ways according to sex. The most socioeconomically disadvantaged were single-parent women. Inequalities in health differ markedly by sex but vary little according to single-parent status. Conclusions: An uneven distribution of socioeconomic resources might help us to understand why single-parent, both women and men, have worse health than parents who live together. Previously recognized sex gap with regard to health status also might help us to understand the difference in health between single-parent men and single-parent women found here.

Bong-amsa Temple is a special temple in the custody of Jogye sect, a branch of Buddhism in Korea. Due to limited public access to this temple, its Geungnakjeon(paradise shrine) has been little known to outside. But it is known that the Geungnakjeon has been not yet explored from academic standpoints in terms of its historical establishment as well as applications, and it would be two-storied wooden pagoda or the like. In order to examine its historical establishment, this study investigated historical records related to Bong-amsa Temple and its intrinsic architectural style. As a result, it was estimated that the building was established around the transitional period ranging from the late Koryo dynasty to the early Joseon dynasty. And it was found that the Geungnakjeon is not the two-storied wooden pagoda, but the unique building including an incidental component called Chayanggan(遮陽間; a sort of stepped penthouse) in Korea. In order to examine its possible applications, this study compared this building with other Buddhist funeral articles in forms similar thereto, such as Buddhist pagoda(僧塔), sarira container(舍利器) and Gamnodo(甘露圖) which depicts Byeoknyeon Daeban(碧蓮臺畔; a palanquin carrying malignant spirit). Then, this study estimated its possible applications on the basis of relevant historical literatures. As a result, it was found that this building was used as Wondang(願堂; a sort of Buddhist prayer house) to wish royal family's going to Nirvana after death, and it was not Confucian-style architecture popularized in the era of Joseon dynasty, but Buddhist-style architecture built widely from the era of Koryo dynasty to the early Joseon dynasty.
