Objectives : Job insecurity, such as non-standard work, is reported to have an adverse impact on health, regardless of health behaviors. The aim of this study was to examine the relationship between non-standard employment and health in Korea. Methods : We analyzed a representative weighted sample, which consisted of 2,112 men and 1,237 women, aged 15-64, from the 1998 Korea National Health and Nutrition Examination Survey. Non-standard employment included part-time permanent, short time temporary and daily workers. Self-reported health was used as a health indicator. Results : This study indicated that women were more likely to report poorer health than men with standard jobs. Of all employees, 20.3% were female manual workers. After adjusting for potential confounders, such as age, education, equivalent income, marital, social and self-reported economic status and health behavior factors, nonstandard employment was found to be significantly associated with poor health among female manual workers (OR, 1.86; 95% CI, 1.24 to 2.79). No significant association was found in other working groups Conclusions : Among female manual workers, nonstandard employees reported significantly poorer health compared with standard workers. This result raises concern as there are increasing numbers of non-standard workers, particularly females.

Purpose: This study was designed to describe the experiences of dementia prevention program for older adults in nursing homes. Methods: Four focus group interviews (FGI) after the program were conducted with 35 participants. All interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed by Colaizzi's phenomenological method. Results: Four themes emerged as a result of analysis. Participants without dementia reported "I don't have dementia yet." This statement probably reflects ignoring potential dementia. Motivation for participating the dementia prevention program were to reduce boredom, to enjoy exercising and communicating with others, and to follow group activities. Participants reported the positive effects of the program; (a) benefits from the repeating learned activities; (b) improvements of memory and emotional stability. A few participants reported their inability to follow the program due to physical and environmental limits. However, other participants reported their efforts to overcome physical limits and perform the activities regardless their limits. People who performed the activities with physical limits reported that their self-satisfaction was increased. Conclusion: Results of this study showed that participants without dementia were able to actively participate in dementia prevention programs and showed memory, emotional and behavioral improvements. Therefore, these findings can be used for developing customized dementia prevention programs in nursing homes.

Since John Davy reported the first well-documented case of occlusive disease involving the branches of the aortic arch in 1839, many similar cases have been reported in literature, especially from oriental countries. The prognosis and symptoms depend on the degree and extent of the occlusive lesions and also on the importance of the arteries affected. The course may progress slowly or rapidly with remissions and exacerbation, and death may result from acute CVA, cardiac failure or pulmonary edema, and renal failure. No medical therapy has been able to alter conclusively the course of the disease, so various surgical procedures have been applied to relieve the obstruction and to prolong the life. We present the case of an 18 year-old female with multiple stenosis of the aorta, and performed the long bypass graft from descending aorta to common lilac artery, and the result was excellent.

In this study, aquatic and aerial algae were collected in various environments in Hongcheon-river of Gangwan-do between December 2011 and June 2012, with the aim of adding newly described genera and species to the Korean flora. As a result, five genera and eight species were recorded for the first time in Korea. These newly recorded genera and species were Cylindrocapsa geminella, Leptosira mediciana, Pseudendoclonium basiliense var. brandii, Stichococcus minor, S. deasonii, Eustigmatos polyphem, Nephrodiella lunaris, and Xanthonema exile. The eight taxa identified in this study mostly corresponded to their reported morphological characteristics. However, some differences from previous published descriptions were found; N. lunaria, reported to be an aquatic species in a previous study, was found to be an aerial algae inhabiting on rocks and mosses. Cylindrocapsa geminella was found to transform into attached or planktonic algae depending on the environmental condition, and the cell wall was found to be changed. Likewise, E. polyphem was seen to change cell-shape or chloroplast color according to the environment.

Taxa in the order Chlorococcales inhabiting Hongcheon River, South Korea were collected and identified from December 2011 to September 2012. As a result, nine taxa in the Order Chlorococcales including unrecorded genera Oocystidium and Heleococcus were newly added to the Korean flora: Oocystidium ovale, Heleococcus mucicola, Chlorella mirabilis, Monoraphidium convolutum var. pseudosabulosum, M. minutum, Raphidocelis mucosa, Eutetramorus tetrasporus, Scenedesmus flavescens, and S. multicauda. The morphological characteristics of the nine taxa identified in this study mostly corresponded to already reported characteristics; however, M. minutum had a shorter cell length than the recorded description, Raphidocelis mucosa and S. flavescens were larger than previous descriptions, and Scenedesmus multicauda had larger spines than the cell itself. Eight of the nine taxa were found in planktonic samples, whereas Heleococcus mucicola was found in an epilithic sample. Therefore the Korean order Chlorococcales, including these newly reported ones, totals to 255 species.

The Chinese sea snake Laticauda semifasciata (Reinwardt in Schlegel, 1837) is newly reported from Korean waters based on three specimens collected from Jeju Island, Korea, in August, September, and November 2015. This is the first time that the genus Laticauda and subfamily Laticaudinae has been reported from Korean waters. The subfamily Laticaudinae has ventrals that are four to five times wider than the adjacent dorsals, which are unlike the ventrals that are similar or up to two times wider than adjacent dorsals in the subfamily Hydrophiinae. Laticauda semifasciata is distinct from other species because it has three prefrontals and its rostrals are horizontally divided into two. As the result of this report, four species (L. semifasciata, Hydrophis (Pelamis) platurus, Hydrophis cyanocinctus, and H. melanocephalus) of sea snakes have been reported in Korean waters.

Conveyors cause a high serious and fatal injuries in the industry. Every year people are hurt or killed as a result of accidents on conveyors. Most accidents occur during operation and maintenance when employees are working on moving, unguarded conveyors or when the conveyors starts unexpectedly. In 2008 there were 486 reported injures ranging from fatalities to injures. Of these 486 reported accidents, 8 were fatalities, 66.9%(325) of reported accidents occurred in manufacturing company and 43.8%(213) occurred at the belt conveyors. The objective of this study was to invent the remote emergency stop device because industrial accidents mainly occur at blind spots where usually do not have any safety guard or device rather than the normal working places. In principle, this new device will use with the existing safety system. Then, it will be powerful safety system for preventing injuries related with conveyors.
