Purpose : The incidence of nonphysiologic neonatal hyperbilirubinemia is twice as high in East Asians as in whites. Recently, UGT1A1 mutation was found to be a risk factor for neonatal hyperbilirubinemia. In congenitally-jaundiced Gunn rats, which lack expression of UDP-glucuronosyltransferase, alternative pathways can be stimulated by inducers of CYP1A1 and CYP1A2 enzymes. CYP1A2 plays a major role in bilirubin degradation of the alternate pathway. We studied the relationship between UGT1A1 and CYP1A2 gene polymorphism of neonatal hyperbilirubinemia in Koreans. Methods : Seventy-nine Korean full term neonates who had hyperbilirubinemia(serum bilirubin >12 mg/dL) without obvious causes of jaundice, were analyzed for UGT1A1 and CYP1A2 gene polymorphism; the control group was sixty-eight. We detected the polymorphism of Gly71Arg of UGT1A1 gene by direct sequencing and T2698G of CYP1A2 by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) using MboII and direct sequencing. Results : Allele frequency of Gly71Arg mutation in the hyperbilirubinemia group was 32 percent, which was significantly higher than 11 percent in the control group(P<0.0001). Mutant gene frequency of T2698G was 41.8 percent in patients and 32.3 percent in the control group(P=0.015), but allele frequency was 21 percent in patients and 19 percent in the control group, which was not significantly higher(P=0.706). There was no relationship between mutations of two genes(P=0.635). Conclusion : The polymorphism of UGT1A1 gene(Gly71Arg) and CYP1A2 gene(T2698G) was detected in Korean neonatal hyperbilirubinemia. Only polymorphisms of Gly71Arg in UGT1A1 were significantly higher than control group.

The purpose of this study is to assess healing effect of the green tea on Staphylococcus contaminated wound. On the back of 7 dogs, 6 full-thickness skin wounds($2cm{\times}2cm$) were made and Staphylococcus intermedius was inoculated. Each wound was applied with the 2%(experimental group I), 1%(experimental group II) extract of green tea and normal saline(control group I) after inoculation. The wound contraction rate of the experimental group I and II was higher than that of the control group in entire period. And from the $6^{th}\;to\;22^{nd}$ day, the wound contraction rate of the experimental group I and II was significantly higher than that of the control group(p<0.05). The occupation rate of wound healing in the experimental group I was higher than that of the control group from $0\;to\;9^{th}$ day except from $1^{st}\;to\;2^{nd}$ day and also higher than that of the experimental group II from $0\;to\;3^{rd}$ day except from $1^{st}\;to\;2^{nd}$ day. And the occupation rate of wound healing in the experimental group II was higher than that of the control group from $1^{st}\;to\;8^{th}$ day except from $2^{nd}\;to\;3^{rd}$ day. According to concentration of green tea extract increased, the wound contracted more vigorously in earlier period. The tensile strength of the experimental group I and II was significantly higher than that of the control group(p<0.05). And that of the experimental group I was also higher than in the experimental group II(p<0.05). The number of S. intermedius in the experimental group I and II was decreased more rapidly than that of the control group. From the $4^{th}$ to the $11^{th}$ day, the number of S. intermedius in the experimental group I was significantly lower than that of the experimental group II and the control group. And from the $4^{th}$ to the $7^{th}$ day, the number of S. intermedius in the experimental group was significantly lower than that of the control group. The histopathological findings of the experimental group I and II were similar to those of the control group on the $1^{st}\;and\;4^{th}$ day. On $14^{th}$ day, reepithelialization was completed in the experimental group I and II except the control group. Higher wound contraction rate, better bacteriocidal action, higher tensile strength and better histopathological findings were observed in the experimental group I and II than in the control group. These results suggest that the topical application of green tea extract can promote contaminated wound healing in dogs.

Background : A pressure sore was defined as any skin lesion caused by unrelieved pressure and resulting in damage to underlying tissue. The health care institutions in the United States were reported the incident rate of pressure sores ranging from 6 to 14 %. Intensive Care Unit needed highest quality of care has been found over 40% incidence rate of pressure sore. Also, Annual expenditures for the care of pressure sores in patients in the United States have been estimated to be $7.5 billion; furthermore, 50 percent more nursing time is required to care for patients with pressure sore in comparison to the time needed to implement preventive measures against pressure sore formation. However, In Korea, there were little reliable reports, or researches, about incidence rates of pressure sore in health care institution including intensive care unit and about the integrated approach like CQI action team for risk assessment, prevention and treatment of pressure ulcers. Therefore, this study was to develop pressure sore risk assessment tool and the protocol for prevention of pressure sore formation through CQI action team activities, to monitor incident rate of pressure sore and the length of sore formation for patients at high risk, and to approximately estimate nursing time for sore dressing during research period as the effect of CQI action team. Method : CQI action team in intensive care unit, launched since early 1996, reviewed the literature for the standardized risk assessment tool, developed the pressure sore assessment tool based on the Braden Scale, tested its validity, compared on statistics including incidence rate of pressure sore for patients at high risk. Throughout these activities, CQI action team was developed the protocol, called as St. Marys hospital Intensive Care Unit Pressure Sore Protocol, shifted the emphasis from wound treatment to wound prevention. After applied the protocol to patients at high risk, the incident rate and the period of prevention against pressure development were tested with those for patients who received care before implementation of protocol by Chi-square and Kaplan-Meier Method of Survival Analysis. Result : The CQI action team found that these was significant difference of in incidence rate of pressure sores between patients at high risk (control group) who received care before implementation of protocol and those (experimental group) who received it after implementation of protocol (p<.05). 25% possibility of pressure sore formation was shown for the patients with 6th hospital day in ICU in control group. In experimental group, the patients with 10th hospital day had 10% possibility of pressure sore. Therefore, there was significant difference(p<.05) in survival rate between two groups. Also, nursing time for dressing on pressure sore in experimental group was decreased as much as 50% of it in control group. Conclusion : The collaborative team effort led to reduced incidence, increased the length of prevention against pressure sore, and declined nursing care times for sore dressing. However, there have had several suggestions for future study. The preventive care system for pressure sore should be applied to patients at moderate, or low risk throughout continuous CQI team activities based on Bed Sore Indicator Fact Sheet. Hospital-wide supports, such as incentives, would be offered to participants for keeping strong commitment to CQI team. Also, Quality Information System monitoring incidents and estimating cost of poor quality, like workload (full time equivalence) or financial loss, regularly in a hospital has to be developed first for supporting CQI team activities as well as empowering hospital-wide QI implementation. Being several limitations, this study would be one of the report cards for the CQI team activities in intensive care unit of an acute hospital and a trial of quality improvement of health care in Korea.

Salt cress (Thellungiella halophila or Thellungiella parvula), species closely related to Arabidopsis thaliana, represents an extremophile adapted to harsh saline environments. To isolate salt-tolerance genes from this species, we constructed a cDNA library from roots and leaves of salt cress plants treated with 200 mM NaCl. This cDNA library was subsequently shuttled into the destination binary vector [driven by the cauliflower mosaic virus (CaMV) 35S promoter] designed for plant transformation and expression via recombination- assisted cloning. In total, 305,400 pools of transgenic BASTA-resistant lines were generated in Arabidopsis using either T. halophila or T. parvula cDNA libraries. These were used for functional screening of genes involved in salt tolerance. Among these pools, 168,500 pools were used for primary screening to date from which 7,157 lines showed apparent salt tolerant-phenotypes in the initial screen. A secondary screen has now identified 165 salt tolerant transgenic lines using 1,551 (10.6%) lines that emerged in the first screen. The prevalent phenotype in these lines includes accelerated seed germination often accompanied by faster root growth compared to WT Arabidopsis under salt stress condition. In addition, other lines showed non-typical development of stems and flowers compared to WT Arabidopsis. Based on the close relationship of the tolerant species to the target species we suggest this approach as an appropriate method for the large-scale identification of salt tolerance genes from salt cress.

As concerned the life and the medical idea of Choo, Tan-Kye(朱丹溪), which it can be summarized as follows by studying. 1. Tan-Kye(丹溪) lived in the end of the won dynasty(元代末期), When the people starved and suffered from a flood-disaster and drought. etc, also the social conditions were in disorder on account of the corrupt ion of politics. And Cheol Kang seong(浙江省), located in the south region of China, has sterile soil and the climate condition humid and heatful. So the south district peoples have very weak constitution. So We can found that his medical idea reflected the phases of the periods and the regional enviornmental situations. 2. For that reason, Tan-Kye(丹溪) rejected the prescription of the "WHa Che Gook Bang(和劑局方)" which was prevalent at that time, in which the the pungent-dried herbs were widly used ; So he persisted in the "Sang Wha Lon(相火論)" and the "Positivity is usually excedeed while the negativity deficient(陽有餘陰不足論)". Then he treated with the drugs to nourish the negativity for the prime object to be applied in the clinic. 3. Tan-Kye(丹溪) refined the follows from the natural law; Heaven is to the positivity(陽) and the Earth is defined the negativity(陰), so the heaven is to the Macro(大) and the earth, micro(小):So the Sun is to the Positivity(陽), the Moon, the Negativity(陰): as to the Sun is always full while the moon always defected too. Therefore the "positivity is always excedeed for that the negativity is deficientalways(陽有餘陰不足)". In Human body, "the negativity energy (陰精) "is hard formed-easily defected(難成易虧)". And the heat(相火) in the body can be moved easily and let the negative energy to leak out. Therefore the more the positivity excedeed, the more the negativity deficient"(陽當有餘陰常不足). 4. He made it expanded the contents of the "Heat(相火)" in the Chapter Woon Chi of the Nae Kyeong(內徑) and discribed, the Life-string of the human body is originated from the movement of the "Heat with unique energy(相火一氣)". And more in human body, it is specifically regulated by the two visceras, Liver and Kidney, and is distributed in the 'Pericardium(心包絡)' 'Tripie Warmer(三焦)' 'Gallbladder(膽)' etc. In the point of his assertion of heat(相火), it is concluded both the physiological and the pathological heat of all. 5. Tan-Kye(丹溪) grew up in the family or the Confucianism. He was instructed the Confucianism(性理學) from Heo-Kyeom(許謙), the fourth diciple of Chu-Ja(朱子), and was received the Yoo Chang Ri(劉 張 李)'s triple doctrine from the La Tae Moo(羅太無), the second disciple of Yoo Wan So(劉完素). So there are much of content of Confucianism(性理學) in his medical thedry, and his theory has succeeded the achievements of the triple study. 6. About the theory of the "positivity is usually excedeed while the negativity deficient"(陽常有餘陰常不足論) of Tan-Kye, it was asserted that the positivity is never sufficient for the vital mainspring, by Chang, Kye-Pin(張介賓) and Lee, Kyoo-Zoon(李奎晙) etc. And for the Heat theory(相火論), eventhough the scholars of postorior generations criicized all of that, there are defect of the content and unification between them. 7. The father of the "Cha Eum Pa(滋陰派), Tan-Kye(丹溪) contributed considerably to the development of the oriental medicine and to the general therapy for the various diseases(一般雜病施治). 8. there are handed down and remained twenty or more of volumes of list of his writings. Among them, except "Kyeok Chi Yeo Ron"(格致餘論), "Kuk Pang Pal Hyeu"(局方發揮), they are reorganized by posteriority. There are Cho, Do-Chin(趙道震). Cho, Ee-Teok(趙以德), Tae, Sa-Gong(戴思恭), Wang Ri(王履) and Yoo, Suk-Yeon(劉淑淵) etc as disciples of his. And Wang Ryoon(王論) and Woo Pak(虞搏) as the admirer of him.

This study conducted a full survey of the goral population using sensor cameras to identify the exact habitat of the gorals that inhabit Odaesan National Park and for restoration and habitat management-focused conservation projects following the population growth. We surveyed Odaesan National Park for a year in 2018 and selected18 grids (2km×2km) first based on the survey results. We then further divided each grid into four small grids (1km×1km) and installed a total of 62 sensor cameras in 38 small girds divided by four grids(1km×1km). The survey resulted in a total of 5,096 photographed wild animals, 2,268 of which were gorals, and the analysis by the classification table of goral (horn shape (Ⓐ), ring pattern (Ⓑ), ring formation ratio (Ⓒ), and facial color (Ⓓ)) identified a total of 95 animals. The ratio of male and female was 35 males (36.8%), 46 females (48.4%), and 14 sex unknowns (14.7%), while the ratio of female and male excluding sex unknowns was 4 (male):6 (female). The horn shape (Ⓐ) and face color (Ⓓ) were the important factors for distinguishing male and female and identifying individuals. The analysis of the correlation of 81 individuals, excluding 14 individuals of unknown sex, showed a significant difference (r=-0.635, p<0.01). Since the goral population in Odaesan National Park has reached a minimum viable population, it is necessary to change the focus of the management policy of Odaesan National Park from restoration to conservation.

Purpose: The survey was aimed to provide basic data to develop a certification system for hospice and palliative care professionals. Methods: National Cancer Center (NCC) and the Korean Society for Hospice & Palliative Care (KSHPC) conducted the survey for hospice and palliative care professionals who worked at 34 Palliative care units designated by the Ministry of Health, Welfare, and Family Affairs (MW) and the members of the KSHPC. The survey was conducted via e-mail from June 17 to 23, 2009. Total 220 professionals were surveyed. Results: Most of the hospice and palliative care professionals reported a great need for certification system: Physician, 90% (n=51) nurse, 84% (n=134) social worker, 89% (n=35). In regard with the requirement for the certification, a majority of physicians (46%) preferreddiploma course, while social workers (46%) preferred training course for medical social workers. Concerning the certification body, physician (45%) preferred the KSHPC and the MW almost equally, while nurses (50%) and social workers (60%) preferred the MW highly. As for the body to develop and accredit advance training course for each professionals, most of the physicians (51%) preferred the KSHPC, whereas nurses and social workers preferred collaboration of the MW (or NCC) with the professional society, such as the KSHPC (23%), the Korean Hospice & Palliative nurses association for nurses (21%), or the Korean association of (medical) social workers (37%). Lastly, all respondents preferred the course format of once a week, full day, and some field study at weekend. Conclusion: Korean hospice and palliative care professionals identified the great need for the certification system, therefore, the adequate system development must be followed to reflect their voice.

The purpose of this study was to find out how to operate Technology Home Economics in the 2009 revised national curriculum and Home Economics teachers perception on the current states in the middle schools, focused on intensive course-taking, block-time, and total hours to take the course. Data were collected from the 118 Home Economics teachers nationwide through e-mail from May 25 to June 4, 2011, and analyzed with frequencies, percentage, means, t-test, cross-tabulations, and ANOVA. The results showed that Technology Home Economics was intensively taken in the most of all schools(91.5%) during 4 semesters by senior and freshmen or junior. Teachers were relatively less involved in the decision making process for intensive course-taking than did the school managers and dissatisfied with the fact of intensive course-taking. But a few school adopted block-time and most teachers did not think it was necessary. Over half of schools offered the same 16 hours of Technology Home Economics as in the previous 2007 revised curriculum, but nearly 2 out of 5 schools reduced the hours from 1 to 8 with an average of 2.8 hours. To keep the necessary hours to teach the full contents of Technology Home Economics should be protected. The follow-up research needs to be conducted to investigate the changes in the perception of Home Economics teachers.

To develop scab-resistant pear (Pyrus spp.) varieties with fruits that are as crisp and juicy as Asian pears, a cross was made between 'Whangkeumbae' and 'Bartlett' varieties (P. pyrifolia ${\times}$ P. communis) at the Pear Research Institute of the National Institute of Horticultural & Herbal Science, Rural Development Administration, in 1994. Among the 285 seedlings, 'Greensis' was first selected in 2006 for its good eating quality and named in 2012 after regional adaptation tests in nine regions and ten experimental plots from 2007 to 2012. The tree showed a vigorous growth habit and semi-spreading characteristics, like 'Whangkeumbae'. The optimum fruit harvest date was also around Sept. 26 and fruit was round in shape and green in skin color at maturity. Average fruit weight was 470g, and the soluble solids content was $12.4^{\circ}Brix$. The flesh was very crisp and juicy, and had good eating quality. Its' leaf size was similar with 'Bartlett' and smaller than 'Whangkeumbae'. The average of full bloom date of 'Greensis' was determined as Apr. 26, which was six days later than 'Whangkeumbae' and similar with 'Bartlett'. S genotypes of 'Greensis' were identified as $S_4S_e$ by S-allele PCR product sequencing analysis. It seems that the $S_4$ allele was inherited from 'Whangkeumbae' and the Se allele from 'Bartlett'. 'Greensis' displayed strong resistance to scab disease caused by Venturia nashicola, similar to European pear cultivars like 'Beurre Hardy' and, 'Conference'. 'Greensis' was also highly resistant to black leaf spot (Alternaria kikuchiana) in the field

This study was conducted to examine the effect of 0.4% of $CaCl_2$, $2H_2O$, $1mg{\cdot}L^{-1}$ of Calmodulin (CaM)-SH, 250-folds of coating agent (WE-36), 1,000-folds of $GA_{4+7}+BA$ and 3 types of paper bagging treatments on russet incidence and fruit quality attributes of 'Gamhong' apple. The pattern of russet occurrence was slightly different for 4 years (from 2012 to 2015) in 'Gamhong' apple. The russet occurrence was lowest in $GA_{4+7}+BA$ treatment at 20 days after full bloom (DAFB), compared with other treatments. The $GA_{4+7}+BA$ treatment increased fruit weight at 20 DAFB, while the other fruit quality attributes were not influenced. The russet occurrence was lower not only in a single bag application than in untreated ones but also in yellow bagging and discolored bagging applications than in a white bagging application. The russet occurrence in a bagging application was lower at 20 DAFB than at 30 and 40 DAFB, while fruit quality attributes were not affected by bagging applications. The russet incidence was lower in $GA_{4+7}+BA$ twice treatments at 20 and 30 DAFB, and calcium coated bag at 30 DAFB after $GA_{4+7}+BA$ treatment at 20 DAFB than in untreated fruit. The rate of russet incidence was lowest at equator region in $GA_{4+7}+BA$ treatment, compared with the other fruit regions. Overall, the results suggest that one and/or two applications of $GA_{4+7}+BA$ (1,000-folds) treatment at 20 DAFB should reduce the risk of russet incidence in 'Gamhong' fruit.
