Recently, the consumption of soy products has been associated with low rates of hormone-dependent and hormone-independent cancers. Asians, who consume $20{\sim}50times$ more soy per capita than Americans, have lower incidence and death rates from breast and prostate cancer. Because soy contains the isoflavones genistein and daidzein (present as their glycosidic conjugates) at mg/g concentrations, it has been suggested that isoflavones might be acting as natural chemopreventive agents. During the 1980s several groups of investigators carried out experiments to test the effectiveness of soy in the diet in animal models of cancer. These studies reported a protective effect of soy; none showed that soy increased cancer risk. Genistein was shown to inhibit the growth of a wide variety of tumor cell types in culture. The purpose of this study was to evaluate the effects of genistein on the carcinogenesis induced by topical application of 0.5% 9, 10-dimethyl 1,2-benzanthracene (DMBA) on the hamster buccal pouch. 48 syrian hamsters were employed in this study, divided into experimental group and control. 24 animals (DMBA topical application group) had the right buccal pouch painted 3times weekly with 0.5% DMBA in mineral oil, 24 animals (genistein group) were supplied with 0.1mg genistein with DMBA topical application. 3 animals in the experimental group and control were sacrificed at serially each other week after experiments. Their buccal pouches were removed and routinely processed for microscopic examination. The results were as follows: 1. In DMBA topical application and genistein group, they showed carcinogenesis as time goes by experimental stage. 2. Genistein group was retarded in carcinogenesis related to the acanthosis, hyperkeratosis, epithelial dysplasia. 3. p53 immunohistochemical study showed that the p53 protein of genistein group was less expressed than that of the control group. Thus, it seems that genistein has chemopreventive effect on the carcinogenesis in the oral cavity, but further study is required to elucidate the anticancer mechanism of genistein.
Hwabyung is a culture-related disease generally know among people in Korea, and various studies have been done by the Psychiatrists and by the Oriental Medical Doctors. While the Psychiatrists explain the Hwabyung as a disease having a unique patholoical process, the Oriental Medical Doctors explain it as a symptoms having the character of fire. When interpreted in Oriental Medical point of view, this can be concluded as 1)the cause of the disease is the depression of liver-energy(肝氣鬱結) induced by emotional suppression, 2)the reason why the disease occurs mostly to female is that they usually fail overcoming stresses and have physical and visceral weaknesses, 3)the symptoms are associated with the dynamics of fire, because the disease originates from the rising character of fire and from the inadequit supression of extreme heart-fire(心火) by the kidney-wter(腎水), 4)the reason why the disease goes through chronic process is because of the complexed emotions, converted fire caused by prolonged emotional disorder and inapropreate supression of fire with grow older. This results suggest thst the cooperative study of the clinical examination of the Psychiatrsis and the study on the fire by the Oriental Medical Doctors is necessary to establish the process of the disease, the pathological procedure, the prognosis and the method of treatment.

Background and purpose: Gin Ga Chu Yo(該家樞要) was written in the year 1359 by Hwal Su(滑壽) who was a famous oriental doctor between Won(元) and Myeong(明) dynasty. As specialized in sphygmology(脈學), this book was brought together most things about sphygmology(脈學) before Won(元) dynasty by the author. Moreover he added the self-realized things to this book. Methods: In this book, there are all 20 chapters; Chu Yo Hyeon Eon(樞要玄言), Jwa U Su Bae Jang Bu Bu Wi (左右手配臟腑部立), O Jang(五臟), Sa Si peong Maek(四時平脈), Nae Gyeong Sam Bu Maek Beop(內經三部脈法), Ho Heup Chim Bu Jeong O Jang Beop(呼吸沈浮定五臟法), In Ji Ha Gyeong Jung I Jeong O Jang Beop(因指下輕重以定五臟法), Sam Bu So Ju(三部所主), Ji Maek Su Beop(持脈手法), Maek Gwi Yu Sin(脈實有神), Maek Eum Yang Yu Seong(脈陰陽類成 ), Gyeom Hyeon Maek Ryu(兼見脈類), Je Maek Ui Gi Ryu(諸脈宜忌類), Heom Je Sa Jeung Ryu(驗諸死症類) , Sa Jeol Maek Ryu(死絶脈類), O Jang Dong Ji Maek(五藏動止脈), Bu In Maek Beop(婦人脈法), So A Maek Beop(小兒脈法), Maek Sang Tong Hoe(脈象統會), Maek Sang Ga(脈象歌) and an epilogue in the end. This treatise is made up of principal, notes, study and conclusion, we tried to make a translation faithful to the original. Results and Conclusion: Looking into this book, we can know that it is very detail in analyzing item by item, bright and simple in explaining and it is very useful in studying pulse evaluation(脈診). In his preface, Hwal Su(滑壽) expresses his opinion with firm confidence that 'Do(道) of the World scattered in several scholarships and books of method and technique(方術). Nothing of method and technique(方術 ) is more important than medicine. Nothing of medicine goes before pulse evaluation(脈診).' With such good reasons, as a student of sphygmology(脈學), I think this book is very valuable in studying pulse evaluation. So I add Hangul suffixes(吐) to a part of this book and translate it into Korean.

Korea Meteorological Administration(KMA) has issued the tropical storm(typhoon) warning or advisories when it was developed to tropical storm from tropical depression and a typhoon is expected to influence the Korean peninsula and adjacent seas. Typhoon information includes current typhoon position and intensity. KMA has used the Dvorak Technique to analyze the center of typhoon and it's intensity by using available geostationary satellites' images such as GMS, GOES-9 and MTSAT-1R since 2001. The Dvorak technique is so subjective that the analysis results could be variable according to analysts. To reduce the subjective errors, QuikSCAT seawind data have been used with various analysis data including sea surface temperature from geostationary meteorological satellites, polar orbit satellites, and other observation data. On the other hand, there is an advantage of using the Subjective Dvorak Technique(SDT). SDT can get information about intensity and center of typhoon by using only infrared images of geostationary meteorology satellites. However, there has been a limitation to use the SDT on operational purpose because of lack of observation and information from polar orbit satellites such as SSM/I. Therefore, KMA has established Advanced Objective Dvorak Technique(AODT) system developed by UW/CIMSS(University of Wisconsin-Madison/Cooperative Institude for Meteorological Satellite Studies) to improve current typhoon analysis technique, and the performance has been tested since 2005. We have developed statistical relationships to correct AODT CI numbers according to the SDT CI numbers that have been presumed as truths of typhoons occurred in northwestern pacific ocean by using linear, nonlinear regressions, and neural network principal component analysis. In conclusion, the neural network nonlinear principal component analysis has fitted best to the SDT, and shown Root Mean Square Error(RMSE) 0.42 and coefficient of determination($R^2$) 0.91 by using MTSAT-1R satellite images of 2005. KMA has operated typhoon intensity analysis using SDT and AODT since 2006 and keep trying to correct CI numbers.
Magnetoresistance and magnetization of Sr$_{l-x}K_xBiO_3$ were both measured as functions of temperature and magnetic field. Resistivity goes to zero at T=10.1K and the overall superconducting transition behavior under applied magnetic fields is similar to that of other BiO based superconductors. Also, below T<5K we have observed the reappearance of finite resistivity with a power law temperature dependence( ${\rho}$${\sim}$T$^1$); the reentrant superconducting transition of resistivity. Contrary to the Josephson weak link effect in polycrystalline samples, which gives the depression of the superconducting state with increasing electrical current or magnetic field, the superconducting state for T<5K is resumed by applying a higher current or magnetic field. Magnetic susceptibility( ${\chi}$ ) of Sr$_{l-x}K_xBiO_3$ for T<5K also shows similar trends to that observed in transport measurements: increase of ${\chi}$ (paramagnetic-like behavior) at a low magnetic fields(B=50 Oe) and, the resumption of perfect diamagnetism at high fields.
This study was carried out to investigate the eating out behaviors of adults in Jeonju area. A total of 500 adults were surveyed by questionnaires during January 2004. The subjects were aged 20 to over 50 years, and were classified into 4 groups (age $20{\sim}29,\;30{\sim}39,\;40{\sim}49$, and over 50). The data were analyzed using the SPSS 10.0 program. The results are summarized as follows: 78.2% of adults aged 50 and over answered they are 'eats three meals every day' (p<0.05). Breakfast was skipped in 73.3% of $20{\sim}29$ age group(p<0.001). As the age goes up, three meals and breakfast ratio were high. The highest frequency to dine out with a subjects were 2 or 3times a month(31.2%). About 40% of the $30{\sim}39$ age group spent daily $20,000{\sim}30,000$ Won for eating out. Korean foods were the most preferred menu for eating out in $40{\sim}49$ age group(p<0.001). Taste of food was the most important factor in selecting the menu (57.2%). Major source of restaurant information was recommendation by friends or relatives in $20{\sim}29$ age group(p<0.001). Dinner eat out was most frequent(45%) and lunch eat out on dinner eat out was 29%. Especially, 65.8% of $30{\sim}39$ age group was highest.
This study examines the ramp-up analysis techniques which have been introduced till now and presents the strength and weakness of each method. The applicability of each technique was reviewed using a case study involving the data of Cheonan-Nonsan motorway usages where seasonal variations of the data were removed. The results showed that all the techniques except F-test have the same ramp-up period of 12 months. The level of Tamp-up was 65%-72% compared to that of the real traffic volume at the beginning of opening. The demand recovered to the stabilized level as time goes on. To apply the methodology to practical demand forecasts actual surveys of real data of traffic demand should be performed. With these efforts to the patronage ramp-up, more reliable demand analyses can be accompanied.
The national parks of South Korea take up an area of 6,726 ㎢, which accounts for 6.7% of the national land. They are national conservation areas with their area made up of 59.1% of land (3,972.6 ㎢) and 40.9% of seawaters (2,753.7 ㎢). And in 2019, the national parks are classified by type into 17 mountainous, 4 maritime or coastal, and 1 historical site. Here, the maritime or coastal nation parks are lately spotlighted as landmarks in maritime tourism. However, the area of the maritime or coastal national parks is continuously dwindling due to conflicts between the residents in the parks and Korea national park service, the continued pressure with respect to the regional tourism development and private investments, and the abolition of parks in relation to allegedly breached private properties. This study identifies the issues with the operation and management of national parks as caused by the abolition of parks and the reduction of areas, and goes from there to do research with the aim of suggesting an institutionalized improvement plan with a view to more useful operation and management of the maritime or coastal national parks. As a result, the natural resources in the sea and on land should be surveyed again to establish the standard for use-specific zoning and reorganize the park areas in adjusting the national park areas. Second, the use-specific districts need to be reviewed for their reorganization that meets the designation requirements by focusing on the characteristics of the different national parks with a view to ensuring reasonable natural conservation in the maritime or coastal national parks. Third, various support facilities for residents such as public path, lodgings, and rentals need to be created to reduce the conflicts between Korea national park service and those who live in the parks.
In Korea, respect for the aged and filial devotion is treated as basic ethics for human life, and family takes care of the aged person mainly. Nowadays, family support on the aged person is prioritized than the others. However, number of aged person is growing, and family, which is used to protect the aged, becomes nuclear through industrialization. In addition, social advancement of female induces weakened supporting function of family, and all these issues generate the problem of protection for the aged as significant social problems. Author conducted oral inspection and questionnaire for the aged in some welfare facilities in Gyeongnam location from December 2005 to February 2006 to improve quality of life and oral hygiene of the aged. Through gathered data, the actual condition of oral hygiene management on the aged person in welfare facility was evaluated as fundamental data for project development on oral hygiene of aged person. Through the analysis of inspected data, the following conclusions are derived. 1. Management status of oral hygiene is mostly not good, and toothbrushing per day is 'one time' for the most cases. 2. In free-of-charge facility, monthly allowance is 'under 50 thousand won' for the most cases. 3. Time for visiting oral treatment facility is on 'when toothache is occurred' for the most cases. For treatment content, 'prosthetic dentistry' takes 36.8% in charged facility, and 'tooth extraction' is 27.0% for free-of-charge facility. 4. Average DMFT index of the aged in charged facility is 16.81, and free-of-charge facility is 21.71. 5. Average number of functional teeth in charged facility is 15.22, and free-of-charge facility shows 7.29. 6. Average number of remained teeth in charged facility is 15.71, and the umbe in free-of-charge facility is 9.04. 7. Average number of extractable teeth in charged facility is 0.48, and for free-of-charge facility, the number goes up to 1.70.
We carried out this study for recognizing the staue of child inpatient nursing and providing child inpatient with better qualified nursing. We study this research from March 29, 93 to April 23, 93 to April 23, '93. First admission day in hospital, we ask 50 mothers of hospitalized child inpatient about the value of nursing and self-consciousness of mothers, also ask 10 nurse in charge about the satisfaction of tending child inpatient Two times-third admission day in hospital and leaving day, we inquired mothers the value of nursing of mothers by inquiry papers, each measurement was made up of five indexes. The result of research was as follow: 1. The subjects of research had following peculiarities. Average age : 2.5 years 0~ 1 years : 32.0% Baby girl : 56.0% first baby : 58.0% Experienced inpatient : 52.0% The number of hospitalization times was 1~2 times : 61. 5% The average period of hospitalization : 7 days Infected inpatient with respiratory organ disease : 40.0% The mother's average age of child inpatient : 30.5 years Mother's who finished high school : 90.9% Family that income about 600,000-700,000 won : 32.0% Mothers who belived an religion : 50.0% 2. As hospitalization time goes by, mothers gradually failed to recognize the value of nursing. 3. Self-estimated tending satisfactions have no connection with the value of nursing that mothers recognized. 4. The value of nursing was effected by mothers own personnality-salf-consciousness care, experience of hospitalization, academic background & religoin. So, we find out that the value of nursing had no connection with satisfaction of tending. Nurses must make every effort to provide child inpatient with nursing of good quality, that mothers confirm and nurses satisfy themselves. Also, we have to emphasize the importance of home and school education, because these education have a great influence upon mother s self-consciousness.
