Recently some Korean public libraries are operated without considering publicness due to lack of interest of local government and residents. Some local government and residents do not properly understand the role of public libraries, or library community did not play a proper role for this. The purpose of this study is to suggest the role of public libraries based on analyzing statements of public libraries domestically and internationally in light of conception, “public“ and “publicness”. This study investigates general definition and role of public libraries, compares statements regarding public libraries, and suggests the role of public libraries.

To analyze the suicide patterns of Koreans, a research study was conducted from the suicide cases taken from the Dong-A Newspaper from 1981 to 1990. Four hundred and eleven cases were obtained from the collected data, which were composed of 275 cases of males and 136 cases of fe-males. The age groups were classified into 6 groups for convenience, 10's, 20's, 30's, 40's, 50's, and 60's. The group differences were then compared for analysis. The characteristics in relation to the socio-demographics and family environment were conpared for analysis. Suicide types compared and analyzed by gender and age group in terms of frequency, type, time, place, method, motivation, location and size of articles, and risk factors for suicide. Sta-tistical analysis used SPSS/PC^+ for cross-tabulation analysis. 1. In relation to the rate of Koreans' suicide, male suicide rate was at least double that of fe-male(2.02 : 1). The age group of the 20's(118 cases) and 30's(96 cases) accounted for a pre-dominant rate of 52.6% of the sample. 2. The distribution of occupation of suicides showed that most were students(22.5%), followed by the unemployed(17.8%) and housewives(12.7%), retrospectively. In relation to the residency of those that had committed suicide, residents who lived in large cities accounted for the greatest number as 70.3%, Especially, females and cases in their 40's were more likely to live in large cities. In the marital status, singles were in the lead(144 cases, 33.0%). With respect to marital status by age group, cases in their 40's(17.4%) tended to have an unstable status such as divorce, separation, co-habitation, remarriage, or widowed, In birth order, the first child were the highest ones as 22.1%. 3. In relationship to the family structure, data revealed that nuclear families were the most(163 cases). Especially, males and cases in their 40's were likely to be form a nuclear familiy, while those in their 60's were from and extended family. In relation to parental survival, data showed that both parents dead were at the highest frequency as 264 cases. In case of female, loss of both parents were more frequent. 4. With respect to the frequency of recurrent suicide, data presented that 6.3% of the cases ex-perienced recurrent suicide. In case of the recurrent suicide of male(8.0%), the rate was about 2.3 times higher than of female(2.9%) 5. For the relationships of homicide and suicide, data showed that 128cases(31.2%) hurt others and attempted suicide. Among them, 96 cases(23.4%) attempted co-suicide and 32 cases(7.8%) attempted homicide others. Analyzed by the characteristics of gender and age group, 10's males were more likely to commit solo-suicide, women in their 30's or 40's commit co-suicide, and 50's commit suicide after homicide. Among the victims of homicide, family members were the most(42 cases). Analysis by age difference between the suicide partners, the cases of 30's or 40's were with family members, 20's with lovers, and 10's with their peers. 6. In relation to the annual distribution of frequency of suicide, data revealed that most cases of suicide were reported in 1990(95 cases), 70 case in 1981, 45 cases in 1982, 44 in 1983, 30 in 1986, 1987, 1989, each, the fewest cases were in 1985(14 cases). In terms of the trend of sui-cide, recently the rate of male and old cohorts over 50's has been increasing. A great number of suicide were in 1981∼1982 and 1989∼1990, the period of a treat political-economical up-heaval. On the other hand, the number of suicide was low during the period of political-economical stability of 1985 and of political thawing in 1988. These fact demonstrated that there were some relationships between political-economical change and the rate of suicide. 7. For the month of suicide, data showed that the highest frequency of cases were in May and June(21.7%), followed by 44(10.7%) in September. For the season of suicide, the fewest cases were in winter(78 cases). The cases of 10's or 20's were more likely to suicide in May and June, and those of older aged group above 50's in fall, weekend, between 1 : 00∼6 : 00 A.M. 8. With respect to the place of suicide, data presented that in most cases suicide was attempted at home(210 cases). Compared by gender, the rate of femal's suicide at home(71.3%) was remarkably higher than that of male's(41.4%). On the other hand, the rate of male's suicide in indoors was much higher(36.4%) than that of female's(15.4%). Analyzed by age groups over 50's were more likely to attempt suicide at home, 30's in indoors, 20's in the office or outdoors. 9. For the methods of suicide, 31.9% resort to intoxication followed hanging(21.9%), jumping(13.1%), burning(10.2%), CO poisoning(6.1%), gunshot(3.9%) or drowning(2.9%), Compared by gender, while females were more likely to take such passive methods as intoxication or CO poisoning, males were more likely to take rather fatal methods such as hanging, burning, gunshot. 10. In relation to the general motives of suicide, data showed that economic poverty was the lead(20.9%), followed by emotional conflict(19.2%), marital conflict(16.1%), demonstration(8.5%), health problem (6.3%), school problems(5.8%), and job problems(5.6%). Analyzed by age group, in case of 10's adolescent conflicts such as school problems, scolding of parents of teachers, mockery, and frustration were the major motivations of their suicide, in the cases of 20's hetero-sexual problems, job and demonstration were their motivators. In case of 30's marital and legal problems were the motivators, economic problems in the age of 40's, loss of objects in 50's and health problems in 60's were their major motivations of suicide. 11. Analyzed by subtypes of suicide in the socio-psychological perspective, data showed that fatalistic suicide was the most frequent(30.2%), followed by anomic suicide(29.4%), egoistic suicide(21.7%), altruistic suicide(11.2%). Whereas in case of males altruistic and egoistic suicide were relatively more frequent, in case of females fatalistic and egoistic suicide were relatively more frequent. Analyzed by age group, fatalistic suicide in the 60's, anomic suicide in the 40's, egoistic suicide in the 10's adolescents and altruistic suicide in the 20's were more frequent. 12. For the psychodynamic factors of suicide, data revealed that most cases were escape from despair and loneliness(28.5%), followed by revenge toward the objects that hurt him or her(14.8%), inferiority(12.7%), escape from a conflict situation(11.4%), altruistic(7.8%), self-punishment for guilt(6.8%), pessimism(3.9%), reunion fantasy(1.0%), and other(13.1%). Whereas the psychodynamic factors of males were altruistic and inferiority, those of females were despair and revenge. Analyzed by age group, incase of old age groups over 50's despair and loneliness were the major fcators, revenge in the 30's and 40's, altruistic in the 20's inferiority and escape from a conflict situation in the 10's were more frequent psychodynamic factors. 13. With respect to the suicide risk rescue factors, data showed that as the helpers at the time of trying suicide, family members were the most(111 cases). Family members as helpers were more frequent in the case of females and in those of 10's or 60's. While passerbys were more frequent in the case of males and in those of 50's. For the suicide notes, 17.3% left the notes behind and those in their 60's males were more likely to have a relatively higher rate of leaving motes behind. 14. In relation to the experience rate of the suicide risk factors, data demonstrated that 16.8% had a history of depression which comprised the highest rate, followed by an alcoholism history(10.0%), unemployment and retirement(7.1%), recent death of intimates and separation(4.6%), health change(3.2%). Analyzed by gender and age groups, males were more likely to have an alcoholism or depression history, those in their 40's were more likely to have an alcoholism history than those of any other age group cohorts.

김동욱,신선혜,김혜진,류선,이선희,장철훈,김영대,곽임수 대한감염학회 2004 감염과 화학요법 Vol.36 No.1

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.

We examined empirically the causes of the lead-lag relation existing in Korean stock returns, using the daily return data from 1985 to 1995. We have run the regressions of the lead-lag measures of the stock returns compared to the bench mark portfolio return on firm-sizes, trading frequencies, institutional investor's ownerships, trading volumes, and the standard deviations of returns and found the empirical evidences as followings. First, we found that the stock returns of small firms lagged the ones of the large firms. Also, the returns on less trading stocks lagged those on more trading stocks. Second, The impacts that size, frequency and volume have on the lead-lag relation of the stock returns are appeared to have the directional consistencies regardless to the analysis periods. Third, the institution's ownerships have the slightly different effects on the lead-lag relation of the stock returns according to the analysis periods. Finally, The impacts that the standard deviations of the stock returns have on the serial correlations of the stock returns have shown the considerable differences on its directions and degrees according the the analysis periods.

Residual wall thicknesses, corrosion rates, and residual life of thirty four samples of cast iron pipes(CIPs) and ductile cast iron pipes(DCIPs) collected from water mains of B city were studied to estimate their remaining service life or optimum time of rehabilitation. The internal maximum corrosion depths of samples measured using a dial gauge after shot blasting were twice higher than the external in most cases. Therefore corrosion of water pipes was much more affected by internal water quality than soil. Residual wall thicknesses of DCIPs were higher than those of CIPs. That reason was thought to be that DCIPs have been protected from internal corrosion by lining cement mortar. Residual life calculated by maximum corrosion rate was ranged up to 44 years with 12.40 years average. Since most CIPs were much deteriorated, rehabilitation plan should be established soon in B city. Residual life of DCIP was 33.52 years average. When cement mortar lining is used up by neutralization of DCIPs. DCIP also should be rehabilitated.

This study was Carried out to analyse species composition, species diversity and structure and variation trends of vegetation, of Mt. Odae, Mt. Sobaek, and Mt. Juwang following various latitudes and topographies which were in middle temperate zone in Korea. Obtained results are as follows : 1. As a result of the simple discriminant analysis, soil texture Showed the highest high percent contribution of each environmental factor to the discriminant of Studred area. And Mt. Odae showed high content of sand while Mt. Juwang Showed silt. 2. Mean stem density showed highest value in Mt. Juwang and mean D. B. H. was Mt. Odae, and on phisiographic locations showd high values of stem density and mean D. B. H in slow slope area, nothern aspect area, and high elevation area, in order. 3. Species that showed the highest importance value in each canopy-subtree-shrub layer in study area were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba were in Mt. Odae, Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora were in Mt. Sobaek, and Pinus densiflora-Acer pseudo-sieboldianum-Lindera obrusiloba were in Mt. Juwang. 4. Species that showed the highest importance value in each canopy-subtree-shrub layer on the physiographic location were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in nothern slope, Carpinus laxiflora-Styrax obassia-Lindera obtusiloba in low elevation, and Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora in high elevation. 5. According to decrease of latitudes with going down from Mt. Odae to Mt. Juwang, the more Number of species and individuals were increased, and the deversity index was the highest value in Mt. Sobaek, the evenness was in southern aspect, and the dominance was in high elevation. 6. As a result of Cluster analysis, the study area were divided into 4 groups, Carpinus laxiflora community, Styurax obassia community, Deutzia parviflora community, and Quercus mongolica community. 7. As a result of COA analysis, communities of the study area were divided into Betula platyphylla var. japonica community, Deutzia parviflora community, Quercus mongolica-Acer pseudo-sieboldianum community, and species were divided into 4 groups as the major, the disturbed, the waterside, and the fertile. 8. As results of the simple discriminant analysis and the linear regression, sand and silt content, slope aspect, total nitrogen content, and elevation among environmental factors had high percent contribution to classification and ordination of vegetation communities of the study area. 9. Major tree species had the unstable layer structure due to lower importance values of canopies and subtrees than those of shrubs, and Pinus laxiflora and Betula platyphylla var. japonica were on the decline phase due to very low dominance and absence of next generation. while, Styrax obassia and Acer pseudo-sieboldianum were sustanable layer structure as being distributed on all the crown layer.

Fluoxetine 투여후 발생한 추체외로증후군 3례

이정호,이기철,곽동일,정인과,남민 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.2

The selective serotonin reuptake inhibitor fluoxetine is one of the most frequently prescribed drugs for the treatment of depression and other psychiatric disorders. In the few years, there have been several reports of adverse effects encountered during coadministration of fluoxetine with or without other psychotropic drugs. We experienced three cases of extrapyramidal symptoms were developed when admini-stered fluoxetine alone and with neuroleptics. We conclude that there is a probable or possible causal relationship between fluoxetine and extrapyramidal side effects. The pathogenesis of such adverse reactions, which may be hetero-geneous, is unknown, but it has been suggested that they might be caused by serotonergically mediated inhibition of dopaminergic transmission. From reports in those cases, it appears that fluoxetine alone may be associated with extrapyramidal side reactions. Furthermore the potential for increased levels of concomitant psychotropic medicines and increased side effects, should be borne in mind.
