A survey was performed to 174 male young men who were living alone(40 persons) and shared living with friends(4143 persons) in Chungnam province. Their average age was 22.6 years old, height 171.8 ㎝, and weight 65.6 ㎏. Their daily calcium intake level was averaged 271.9±169.1 ㎎, which was 38.8 %RDA. Comparing calcium intake of each mealtime, breakfast, lunch, dinner, and snacks were composed of 18.6%, 30.0%, 34.0% and 17.4%, respectively. Their daily iron intake level was averaged 8.9±10.8 ㎎, which was 74.3 %RDA. Comparing iron intake of each mealtime, breakfast, lunch, dinner, and snacks were composed of 15.4%, 33.6%, 36.3% and 14.7%, respectively. These results suggested that deficiency of the two minerals in young male adults were severe and the nutrient qualities were also poor, no matter of their living alone or with accompanies. The deficiency was more profound in calcium than iron. And we observed iron nutriture differed significantly according to their living status, such as iron intake and its %RDA were significantly worse in single living subjects than the others. However calcium did not show significant difference. We concluded that shared living environment in young male adults could possibly improve their dietary mineral intake levels.

This study confirms the initial and aftermarket's performance of IPO across the information asymmetry, signaling effect in the Korean Stock Market. Performance is measured by market adjusted excess return. Also, to find out what variables can explain that performance, there exist various empirical tests by regressing the firm specific variables. For this purpose, two hypothesis were made concerning the existence and causes of the early abnormal returns of IPO stocks. In June, 1988 when the governmental interference in pricing of IPO share was lifted, the offer price was set through direct negotiation between the issuing firm and underwriter. Yet, even with the adoption of liberalization reform, the high level of excess returns is still observed in the Korean IPO market. Therefore, IPO stocks employed here were from 269 firms, open to the market from 1988. 6.(the liberalization period) through 1994. 12. The main results of the tests can be summarized as follows. First, The positive excess returns were confirmed and the initial day market adjusted return is statistically significant at the level of 55.27%. Second, Using the size of issue and, capital after offering and the life of firms as a proxy of ex-ante uncertainty and the initial abnormal return of IPO. The weighted competition ratio also has a positive relation with the initial abnormal return of IPO. Third, Firms that do not issue equity after their IPO, are less underpriced than otherwise. This result shows that underpricing of IPO signals that the firm is good for investment, because only good firms can recoup the loss after. Also, Initial abnormal return is negatively related to the share fraction of the issuer. In conclusion, buying the IPO in the primary market and selling them in the secondary market seems, on average, to be a good strategy. Investors in Korean IPO market can gain excess return due to underpricing at the offering.

Among the three anomalies related to the IPO market, most of the studies up to now have been focused on the short run underpricing, and studies concerning long run price behavior are insufficient in a way. But outside Korea, a number of studies show that short-selling has more advantage. On the other hand, in Korea studies concerning long run price behavior are lacking and cannot show the characteristic of the IPO with satisfaction. So the following study will try to take a look at long run performance of IPO. Therefore, IPO stocks employed here were from 269 firms, open to the market from 1988. 6. through 1994. 12. The main results of the tests can be summarized as follows. The long-run performance wasn't consistent with worldwide poor aftermarket evidence. On the contrary, the long-run performance produced better return compared with the average market return. Also, In the analysis of the cumulative abnormal returns for 36 months by way of the wealth relative, once used by Ritter, the Korean IPO stocks obtained superior long-run performance unlike in the previous research concerned. In conclusion, buying the IPO in the primary market and selling them in the secondary market seems, on average, to be a good strategy. Investors in Korean IPO market can gain excess return due to underpricing at the offering.

So the following study will try to take a look at performance of IPO and investment bankings, reputation. Therefore, IPO stocks employed here were from 269 firms, open to the market from 1988. 6. through 1994. 12. The main results of the tests can be summarized as follows. The study regarding the impact of underwriter reputation on initial abnormal return of IPO can be rejected. This finding implies that underwriters play significant role in IPO pricing and after market price management ability in Korea. Therefore, if it is assumed that underwriter do not have perfect information but do have a probability of the true value of the issuing firm, he has a reasonable motive to underprice the the offer price substantially. The more imperfect his information is, the more low the issue price. In conclusion, The results of this paper suggest that strict regulations and procedures governing the pricing of IPOs be more liberalized in order to reduce the severe underpricing of IPOs. Such a measure will induce investment bankers to make more efforts to produce reliable and sufficient information about the true value of the issuing firm.

Purpose: The purpose of this study was to provide appropriate spiritual and comprehensive nursing care for elders admitted to hospital by identifying factors that affect their quality of life, anxiety about death, and spiritual well being and by identifying correlations between these variables. Method: From April 23 to June 30, 2007, 76 patients 65 years of age or older, admitted to the Bobath Memorial Hospital were enrolled in the study. The elders were questioned about their quality of life, anxiety about death, spiritual well being, and their demographic characteristics. The data were analyzed using t-t.est. ANOVA, and coefficient with SPSS for Window version 10.1. Result: This study shows that for most of the elders, quality of life was found to be higher than average at 3.29 out of 5.00. Also, anxiety about death was found to be higher than average at 2.45 out of 4.00. However, spiritual well being was found to be lower at 2.75 out of 6.00. The study showed that as quality of life improves, anxiety about death was reduced. There was no direct relation between quality of life and spiritual well being. There was no direct relation between anxiety about death and spiritual well being. Quality of life for elders was found to be related to gender (p=0.008), economic status (p=0.019), and relationship with family (p=O.OOO). Anxiety death was affected most by job (p= 0.024) and period of hospitalization (p =0.043). Spiritual well being was affected by education(p=0.014), religion (p=O.OOO), and children (p=0.028). Conclusion: The purpose of the study was to improve nursing services for elders admitted to hospital to improve the quality of their lives and spiritual well being and to reduce anxiety about death.

목적 : Vancomycin-resistant enterococci (VRE)로부터 S. aureus로의 vacomycin 내성 유전자의 전파는 오래전부터 예견되어져 왔으며 큰 걱정거리로 남아있다. 최근에 vanA 유전자를 가지고 있는 vancomycin-resistant S. aureus 2주가 미국에서 분리되었다. 이 연구의 목적은 VRE를 보균하고 있는 환자들에서 S. aureus 보균양상과 항균제 내성을 알아보는데 그 목적이 있다. 재료 및 방법 : 2001년 1월부터 2001년 12월까지 부산대학교병원에 입원하였던 환자들 중 임상검체에서 VRE가 분리된 환자 7명과 2001년 9월부터 12월까지 외과 중 환자실에 입원하였던 환자들 중 VRE 감시배양을 시행하였던 20명의 환자들을 대상으로 하였다. 환자들은 전비공, 액와부, 회음부, 직장에서 매주 면봉으로 검체를 채취하였다. 선별배지에서 검체를 배양하여 S. aureus를 분리하였고 원판 확산법을 이용하여 methicillin 감수성을 측정하였다. Broth microdilution 법으로 vancomycin MIC를 측정하였다. 결과 : 총 27명에서 73회의 방문과 292회의 배양이 시행되었으며 총 67주의 S. aureus가 분리되었다. 이중 64주(95.5%)가 methicillin 내성이었다. 전비공 MRSA 보균율은 VRE를 보균하고 있었던 환자는 19명 중 11명(58%)에서, VRE를 보균하지 않았던 환자는 8명 중 3명(37.5%)으로 VRE 보균자에서 보균율이 더 높았다. 총 64주의 MRSA의 vancomycin MIC의 분포는 0.5-2㎍/mL였으며 2㎍/mL를 초과하는 균주는 발견되지 않았다. 64주 중 vancomycin MIC가 1㎍/mL인 균주가 54주(84.4%)로 가장 많았으며 2㎍/mL 6주(9.4%), 0.5㎍/mL 4주(6.3%)의 순이었다. 결론 : VRE 환자에서 S. aureus의 보균율은 비보균자 보다 높았으며 분리된 균주들은 대부분 MRSA였다. VRSA 균주는 발견되지 않았다. Background : The transfer of vancomycin resistance from vancomycin-resistant enterococci (VRE) to Staphylococcus aureus has been predicted. The purpose of this study is to determine the prevalence and antibiotics resistance of S. aureus among patients colonized with VRE. Methods : Between January 2001 and December 2001, a prospective study was performed at Pusan National University Hospital on 27 patients. Surveillance swabs from nasal cavity, axilla, perineum, and rectum were obtained at weekly intervals. Methicillin susceptability of S. aureus was determined by oxacillin disk diffusion test and minimum inhibitory concentration (MIC) for vancomycin by microdilution broth test. Results : Total of 292 swab cultures were performed and 67 S. aureus isolates were collected. 64 isolates (95.5%) were resistant to methicillin. The prevalence of nasal MRSA carrier in 19 patients colonized with VRE was higher than that in 8 patients not colonized with VRE (58% vs. 37.5%). In 64 MRSA isolates, MIC (㎍/mL) for vancomycin ranged from 0.5 to 2. No isolates with MIC >2 ㎍/mL were observed. MIC of 1 ㎍/mL was shown (observed) in 54 isolates, 2 ㎍/mL in 6 isolates, and 0.5 ㎍/mL in 4 isolates. Conclusion : The prevalence of S. aureus with colonization of VRE is higher than that without colonization of VRE. Most of S. aureus isolates were resistant to methicillin. VRSA isolates were not observed.

Milk of calcium bile or limy bile is a rare disorder in which the gallbladder lumen is filled with a thick, paste-like, radio-opaque material. Churchman first reported a case of curious deposition of calcium salts within the gallbladder in 1911. Volkmann first used the term Kalkmilchgalle or "milk of calcium bile" in 1926. The radio-opaque material is almost entirely composed of calcium carbonate by weight. The mechanisms by which bile turns limy and radio-opaque or the time required for this biochemical alteration to occur are not well understood. The limy bile is found mostly in a gallbladder complicated by cholecystitis. Recently, we experienced a 33 year old woman who had a milk of calcium bile in the gallbladder lumen. We report this case with a review of literature.

As a result of extensive research efforts on the oriental medicinal herbs, some of their interesting biological activities have been elucidated. In the present study, antifatigue effects of two natural food supplements consisting of oriental herbs, Vital and Vigilor, were investigated using the ICR mice. The mice were fed with antibiotic-free normal mouse feed containing Vital or Vigilor for 14,28, or 31 days and then subjected to forced swim tests. In a test carried out in melting-ice water, Vital and Vigilor significantly increased the exhaustion times of the 28 day-fed mice by 26.9 % (p < 0.01) and 16.2% (p < 0.05), respectively. However, in the other test performed at 15±0.5℃ using 31 day-fed mice, Vigilor failed to increase the exhaustion time significantly (at p< 0.05), while Vital showed antifatigue effect by increasing the swimming time by 29.9% (p<0.01). Neither of Vital nor Vigilor exerted antifatigue effects in a swim test carried out on day 14 after the initiation of feeding. These results suggest that Vital and Vigilor exhert antifatigue effets when administered for a sufficient period of time by enhancing the health of the host animals.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.
