The compatibility of cyclosporine and methylprednisolone at simulated Y-site administration was studied by this research. Each cyclosporine (CP) to methylprednisolone (MP) was diluted in the concentration 0.5 ㎎/㎖ and 1.25 ㎎/㎖ respectively. As diluent, 5% dextrose water (D5W) or normal saline (NS) was used. Each the above diluted solution was mixed in the 1:1 ratio by the following compositions : a) CP/D5W + MP/D5W ; b) CP/D5W + MP/NS ; c) CP/NS + MP/D5W ; 4) CP/NS + MP/NS. After that, each mixture solution a), b), c), and d) was checked for precipitation, pH and the concentrations at 0, 0.5, 1.0, 2.0, 3.0, 4.0 hrs after mixing by the HPLC method. As the result, all of the above mixture solutions had no precipitation, and no significant pH differences (7.04∼7.30). Also, over the 4 hour study periods, the content of each cyclosporine or methylprednisolone was more than 90% at all the time. This study has been showed the diluted cyclosporine and methylprednisolone was compatible at Y-site administration, and it can be possible to apply for the further patient care.

Purpose: The purpose of this study was to investigate the health-related quality of life (HRQOL) among female college students living alone and analyze the relationship among HRQOL, eating habits, residential environments and social support among female college students living alone. Method: Using a descriptive correlation study design, 151 female college students living alone were recruited through convenience sampling. Instruments were the social support tool developed by Park(1985), residential environment tool developed by Kim and Nam(2015), eating habit tool developed by Park et al(2005), modified by Choi(2012) and the HRQOL tool developed by EuroQol Group(1990). The data were analyzed by average, standard deviation, percentage, t-test, ANOVA, and scheffe test, Pearson’s correlation coefficient using the SPSS 22.0 Version program. Results: Participants’ economic level showed statistically significant differences in social support.(F=4.33, p=.009). There was a statically significant relationship among the types of resident and residential environment evaluation score.(F=4.33, p=.009). Also, there were correlations between HRQOL and social support(Pearson’s r=.165, p=.043), residential environment evaluation score.(r=.284, p<.001). There was a correlation between social support and residential environment evaluation score(r=.202, p=.013). Eating habit showed a correlation between emotional support(r=.164, p=.044) and residential environment evaluation score(r=.200, p=.014). However, perceived health status and eating habit were not significantly associated with HRQOL. Conclusion: As a result of this study, the following conclusions were obtained. There were strong relationships among social support, residential environment and HRQOL in female college students living alone. These findings implied the importance of framing university's guideline and overnment’s policy such as financial support, residential counsel and mental health programs to improve HRQOL for female college students living alone. Since the importance of HRQOL has acquired a great importance, it is critical to collect the data of related factors of HRQOL considering only little research on female college students living alone has been done.

200 GeV/핵자 유황이온과 핵건판핵의 충돌에 의해 생성된 헬륨 파쇄핵의 극한파쇄 연구

고에너지 중이온 원자핵과 핵건판의 충돌에서, 200GeV/핵자 유황이온에 의해 생성된 파쇄 헬륨핵(Z=2)의 실험실계의 방출각 분포는 표적핵에 무관한 회귀공식. dN=exp[a+k exp(η-y_b)]d[exp(η-y_b)]로 잘 표현된다. 여기에서 의사신속도 η=-ln[tan(θ/2)]이고, y_b는 실험실계의 입사입자(^32S)의 신속도이다. 이 공식에 의한 적합에서 k=-0.057±0.008로 얻어진다. 즉, 핵건판과 고에너지 중이온의 충돌에서 파쇄 헬륨핵의 exp(η-y_b)의 분포는 "극한파쇄" 현상을 잘 설명하고 있다. The angular distribution of emission angle θ of helium (Z=2) produced in the collisions of incident particles of 200 GeV/nucleon ^32S in nuclear emulsion is well expressed by dN=exp[a+k exp(η-y_b)]d[exp(η-y_b)] where the pseudorapidity is η=-ln[tan(θ/2)], the laboratory system primary rapidity is y_b, and k=-0.057+0.008. The shape of this frequency of occurrence distributions in terms of exp(η-y_b) attests to the validity of the concept of "limiting fragmentation" for helium projectile fragments produced in the projectile fragmentation regions of heavy ion collisions in nuclear emulsion.

Structure of Li₅AlS₄ and comparison with other lithium-containing metal sulfides

Lim, H.,Kim, S.C.,Kim, J.,Kim, Y.I.,Kim, S.J. Academic Press 2018 Journal of Solid State Chemistry Vol.257 No.-

Lithium aluminum sulfide (Li<SUB>5</SUB>AlS<SUB>4</SUB>) was synthesized by solid state reaction, and its crystal structure was characterized by ab initio structure determination on the basis of powder neutron diffraction (ND) data. Li<SUB>5</SUB>AlS<SUB>4</SUB> was found to have monoclinic unit cell (space group, P2<SUB>1</SUB>/m) with the lattice parameters: a = 6.8583(4)A, b = 7.8369(4)A, c = 6.2488(4)A, and β = 90.333(4)<SUP>o</SUP>. This structure is built from a hexagonal close-packed (hcp) arrangement of sulfur atoms with a stacking sequence of ...ABAB.... The hcp sulfide lattice consists of two different double-sulfide layers alternately stacked along the c-axis. Between the first pair of sulfur layers all the tetrahedral interstices (T<SUP>+</SUP> and T<SUP>-</SUP> sites) are filled with lithium and aluminum atoms. All octahedral interstices between the second pair of sulfur layers are occupied by the remaining lithium atoms. The structure of Li<SUB>5</SUB>AlS<SUB>4</SUB> is compared with those of various lithium-containing metal sulfides like Li<SUB>2</SUB>FeS<SUB>2</SUB>, NaLiMS<SUB>2</SUB> (M = Zn, Cd), Li<SUB>4</SUB>GeS<SUB>4</SUB>, LiM'S<SUB>2</SUB> (M' = Al, Ga, In) and γ-Li<SUB>3</SUB>PS<SUB>4</SUB>. Each sulfide represents a specific distribution of lithium atoms in the lattice depending on how the octahedral and tetrahedral interstitial sites are filled. The low ionic conductivity of Li<SUB>5</SUB>AlS<SUB>4</SUB> (9.7 x 10<SUP>-9</SUP>Scm<SUP>-1</SUP> at 323K) relative to other sulfides may be due to the highly-ordered distribution of the lithium atoms in the layered structure and the lack of adjacent void spaces that can be used for lithium ion hopping.

군장병의 헌혈을 통한 말라리아 전파의 위험성에 대한 조사

임채승,김영기,이갑노,염용태,김순덕,김대성,황유성,오홍범,김두성 대한감염학회 1997 감염 Vol.29 No.2

목적:국내 헌혈 혈액에서 전염병 감염 방지를 위해 시행하는 감염표지자 중 말라리아를 검출하려는 노력은 최근의 비무장지대 내의 군장병에서의 말라리아 재발생에도 불구하고 활성화 되어 있지 않다. 일반적으로 말라리아가 토착화 된 지역을 거주하거나 여행한 사람 중 말라리아에 걸렸거나 치료한 경력 있는 사람은 치료가 끝난 후라도 3년내에는 헌혈을 금지하도록 규정하고 있다. 저자들은 국내 헌혈의 중요 부분(57.8%)을 차지하는 군인에서 헌혈시 말라리아 전파의 위험성을 파악하고자 본 조사를 실시하였다. 방법:1995년 5월에서 1996년 10월까지 군병원에 입원한 환자중 말라리아로 확진된 174명의 환자에서 면담 및 입원 기록을 추적하여 병력과 헌혈 기록을 확인 한 뒤 헌혈장소, 헌혈일, 헌혈 기록을 확인 한 뒤 헌혈장소, 헌혈일, 헌혈 횟수를 조사하여 환자의 증상 발병일과의 간격 및 연관성 분석하였고 이를 기준으로 공혈 혈액의 수혈시 말라리아의 전파 위험성을 평가하였다. 결과:전체 174명의 환자중에서 1회라도 헌혈을 시행한 사람은 70.7%인 123명에 해당하였고 환자의 증상 시작일과 헌혈일과의 간격은 2일에서 평균 2750일(평균 377알, 표준편차 488일)의 분포를 보였다. 증상시작일과 헌혈일의 간격이 3년 이내인 경우는 전체의 87.8%에 해당하였다. 말라리아 치료후 헌혈을 실시한 경우는 (n=18) 모두 치료 후 3년 이내에 헌혈을 하였다. 헌혈장소는 토착형 말라리아의 호발 지역과 동일하였는데 경기도 파주시(40%)와 연천군(29%) 및 철원(15.5%) 기타(15.5%)순이었다. 결론:한국에서 토착형 말라리아 군인 환자들의 병력조회에서 헌혈에 의한 전염가능성이 존재하는 기간 내에 헌혈이 적지 않게 실시되고 있어서 이들 지역에서의 군헌혈을 실시하는 경우 엄격한 헌혈자 선별기준 적용되어야 할 것으로 생각된다. Background: Screening of donor blood for malaria has not been activated in Korea yet in spite of the recent resurgence of tertian malaria among Korean army soldiers in Delimited Militarized Zone areas. Prospective donors(travellers, immigrants, refugees, citizens or residents) following a visit to or coming from and endemic area who have had malaria or taken antimalarial prophylaxis should be deferred for 3 years after cessation of therapy or after depature from malarial area. We studied the risk of the transmission of malaria, especially through army blood donation which comprised up to 57.8% of whole blood donation in Korea. Methods: The data were collected by personal interview and review of donation records of Korea Red Cross Center and medical records from 174 army soldiers with malaria who admitted to Army Hospital from May 1995 to October 1996. We analysed the time interval between onset of illness and blood donation, and geographic distribution of the patients. Results: About 70.7%(123/174) of the patients donated blood before the onset of illness, and the internal between blood donation and onset of illness ranged from 2 days to 2,750 days (mean 377, standard deviation488). Patients who donated blood within 3 years before onset of illness were 87.8%(n=108) of the total blood donation. All donation (n=18) after treatment were within 3 years from 46 days to 342 days(mean 138, standard deviation 80.7). The frequent of blood donations were from the prevalent areas of malaria such as Pajoo City(40%), Younchon Kun(29%), Cholwon Kun(15.5%) and others(15.5%). Conclusion: We showed that donated army blood a risk of malaria transmission. Therefore the blood bank needs to set strict guidelines for blood donation especially from Korean army soldiers to control malaria transmission.
