  • Baby powder is an astringent powder used to prevent diaper rash. It also has other cosmetic uses. In general, it is composed of talc powder (talcum powder). Talc powder is harmful if inhaled because it can cause significant lung damage. With the aim of developing a new rice-based baby powder, three kinds of rice varieties were selected and pulverized. To determine the cost-effectiveness of the different states of rice powder, several milling processes were tried, and the powder characteristics of the resulting rice powder, such as particle size, biological activities, digitalized color value, and moisture content before and after coating treatment with essential oil and silicon oil, were examined. "Goami" showed good flour characteristics with respect to lightness (92.0, $L^*$[D65] value) and particle size ($8.9{\mu}m$). SEM analysis showed that the rice powder particles coated in the essential oil and silicon oil showed a smoother and rounder appearance than those of the talc powder. In addition, the average particle size was decreased by the essential oil and silicon oil coating. The silicon oil coating solved the problem of moisture absorption in rice flour. Rice flour properly coated with essential oil and silicon oil shows great potential as a new material source of powder.

  • In this study, threshold runoff which is a hydrologic component of flash flood guidance(FFG) is estimated by using Manning's bankfull flow and Geomorphoclimatic Instantaneous Unit Hydrograph(GcIUH) methods on Han River watershed. Geographic Information System(GIS) and 3' Digital Elevation Model database have been used to prepare the basin parameters of a very fine drainage area($1.02\~56.41km^2$), stream length and stream slope for threshold runoff computation. Also, cross-sectional data of basin and stream channel are collected for a statistical analysis of regional regression relationships and then those are used to estimate the stream parameters. The estimated threshold runoff values are ranged from 2 mm/h to 14 mm/6hr on Han River headwater basin with the 1-hour duration values are$97\%$ up to 8mm and the 6-hour values are $98\%$ up to 14mm. The sensitivity analysis shows that threshold runoff is more variative to the stream channel cross-sectional factors such as a stream slope, top width and friction slope than the drainage area. In comparisons between the computed threshold runoffs on this study area and the three other regions in the United States, the computed results on Han River watershed are reasonable.

  • Low flow is a minimum flow discharging during a dry season in a unregulated stream which can be shared by nature and human being. It is also a standard flow that determines a diversion requirement by evaluating water supply ability of streamflow in the aspect of water use. Low flow indices are used as average low flow and 1-day 10-year low flow in Korea and Japan and as 7-day 10-year low flow in the United States of America and the United Kingdom. In this research, these three indices were compared by the data observed and generated. Although daily records are needed to calculate the low flow, gauging stations are limited and records of the dry season are insufficient in Korea. Drainage-area ratio method is mainly used in Korea to estimate the low flow. This research shows the guideline when the drainage-area ratio method, the regional regression method, and the baseflow correlation method to calculate the low flow of ungauged basins are applied and recommends low flow estimation method suitable to Korea.

  • A biofilter was established to remove the ammonia, which is representative nitrogen-contained malodorous gas. in a compost factory. Removal efficiency of ammonia and hydrogen sulfide also was investigated. A quantity of malodor gas produced in a compost factory was affected greatly by the weather. compost states and working condition of a fertilizing mixer, and the produced gas concentrations doubled by above various parameters. By operating a water scrubbing system for removing water-soluble malodorous gases effectively. we could improve the removal efficiency over three times. We investigated long-term stability of biofilter under continuous gas flow(SV=500h-1) for 100 days. The results showed 30 days of microbial retention time. After the days, deodorization efficiency of biofilter was kept steady state. and the removal efficiency was kept over 95% for ammonia and 97% for hydrogen so]fide. respectively. The electric consumption of the biofilter, which could treat malodorous gas of 100$\textrm{m}^3$/min, applied in the compost factory was evaluated about 80u0day and water consumption was 80~100$\ell$/day. These results concluded that the biofilter is a excellent deodorization technology as well as cost-effective for removing malodorous gas produced in a compost factory.

  • The purpose of this research is to examine the impact of marriage and parenthood on the physical and mental health, in consideration of gender differences. We have retested various theories including Gove's inequality theory to explain how marriage and parenthood affect the contemporary Korean men and women. This study tries to answer these questions by analyzing the data from ${\ulcorner}$Successful Midlife Development: Survey on Mental health and Work/Family Life Course in Korea and the United States (Han et at., 2001)${\lrcorner}. The data were collected from the survey of 1696 adults (women: 49.5% (n=839)) at the age of 27 to 60. In this survey, physical and mental health were evaluated in three dimensions, respectively: depression, perceived physical health and illness symptoms. The results were that occupying both marital and parental status showed better health profile than possessing other role combinations(single parent/married but no child/never-married). Gender differences and other findings have been discussed further.

  • Acupuncture and moxibustion play an important role not only in the medical service and health care of Korea, China and japan but also in those of many western countries such as Germany, France, United States of America. An unexpected results induced by careless acupuncture and moxibustion treatments may be mild or severe, and are due to practitioner's mistake and particular body condition of a patient. This study was performed to establish a preventive measures against medical accident induced by acupuncture therapy. Total 23 acupuncture points which are included in a J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ were selected as prohibited acupuncture points. Although the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ are an important data historically which show dangerous acupuncture points, there are few a full investigation on J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ up to the present. So present study was done for literature review to understand a feasibility of the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ in association with dangerous acupuncture points. Based upon the locations of these acupuncture points, the dangerous region were classified three categories, head, soma and limb. And abnormal signs related to the improperly performed acupuncture treatment on each point were investigated by using historical reference books on acupuncture and moxibustion. And then names, locations, depth of insertion, operation methods and side effects of each point were investigated.

  • Landscape civilization in Korea originated in Cochosun(Ancient Chosun) era, this again succeeding to the period of the Three States - Koguryo, Baekje and Silla. The distribution of this culture showed great progress with the association of two particular religions - Buddhism and Confucianism.. Landscape development in Korea has greatly changed during specific times of both cultural and political upheaval in various societies. Religion has had a great deal of influence on landscape development. Traditionally Korean people have had a tendency to favor more natural landscape than man-made structures in landscape : This trend was a quite different concept from that of other oriental countries, not to mention of western countries. In particular, Buddhism influenced natural landscape, far from artificial craftsmanship in landscape. Oriental garden is a typical 'tabloid edition' of natural landscape which consists lakes, islands, ponds, stone monuments, and fruit trees, quite often raising animal in parks and courtyard style house. This style of garden influenced in Chosun Dynasty landscape. Landscaping was usually for royal gardens, cemetery parks or high level of officer's residence. However, landscaping in Chosun Dynasty which had established Confucianism as a state religion gave us a specific designation. It was neither ethnic imitation of the garden style of both China and Japan : People were used to enjoy nature-friendly landscape or sink into the ecstasy of natural scenery itself. The trend that landscape or establishing garden had been aimed at royal family- or bureaucrat-centered formatives was to become an obstacle to the development of landscape techniques in Korea. An example represented in a beautiful garden with fabulous decoration which established in places. This was completely not fit for the nation's feeling.

  • Objective: In May 2011, an interview with three United States Forces Korea veterans revealed that chemicals believed to be 'Agent Orange' were buried at Camp Carroll (situated in Waegwan, Chilgok-gun, Gyeongsangbuk-do, Korea) in 1978. Many hazardous chemicals, such as perchloroethylene (PCE), trichloroethylene (TCE), and organochlorines were subsequently found in a joint US-ROK environmental investigation, although dioxins or burial evidence related to 'Agent Orange' have been not uncovered. This study was carried out to investigate the relevance of hazardous chemical exposure and health effects of the residents around Camp Carroll. Methods: The authors conducted a health questionnaire survey among residents around Camp Carroll regarding Waegwan groundwater ingestion, length of residence in Waegwan, and physician-diagnosed disease history (such as cancer, hypertension, diabetes and etc.). Logistic regression was performed to identify the associations between hazardous chemical exposure and physician-diagnosed diseases. Results: Among the 5,320 residents, excluding those living outside the Waegwan area, 3,430 subjects age 30 and over were analyzed. Among females, upon correction of age, smoking history and Camp Carroll working history, a higher distribution in the Waegwan groundwater ingestion group was demonstrated for patients with physician-diagnosed cancer and hypertension. The odds ratios have a tendency to increase with increased length of Waegwan groundwater ingestion. Conclusions: This study may be limited by not adopting a cohort study for the evaluation of factors that may confound environmental exposure. Yet it is meaningful that the correlation between Waegwan groundwater ingestion and chronic diseases were found through regression analysis in female; and further, this outcome may be used as a sampling basis for a secondary epidemiologic study.

  • Endothelin (ET) is a 21 amino acid peptide with multifunctional effects on the vasculature as well as a variety of other cell types such as respiratory, gastrointestinal, urogenital, endocrine, central nervous systems, and others. Endothelin has emerged as a modulator by autocrine and paracrine actions for many cellular activities, including vasoconstriction, cell proliferation, hormone production, neurotransmitter and/or neuromodulator. The endothelin family consists of three closely related peptides, ET-1, ET-2, and ET-3 derived from separate genes, such as chromosome 6, 1, and 20, respectively. ET-1 is the predominant isoform produced in the cardiovascular system and about which most is known. Endothelin receptors are seven-transmembrane GTP-binding protein-coupled receptors, which are classified into endothelin-A (ETA) and endothelin-B (ETB) receptors. Interestingly, recent evidence is accumulating to suggest that ET -1 may contribute to a variety of pain states such as allodynia and hyperalgesia in animals and humans. Therefore, in this review the biological characteristics and contraction-related mechanism of endothelin-1 in mammalian cells will be summarized. Especially, we focus on multifunctional roles for ET-1 in noxious stimulation-induced pain for the study of pain specialized physical therapy.
