This study aimed to provide a basic data for presenting an appropriate plan of bathroom space which is suitable to our bathing behavior. We analized 1052 of small-sized apartment housing floor plans and the results were as follows. 1. Bathroom space were classified into 5 types : bath unit type, separated type, deficisncy type, over bath unit type, and semiseparated type and there was no separated type in this study. 2. The bathroom space type according to the size of housing 1) Deficiency type was the most popular one in 10-15 pyung sized housing. 2) In the size of 16-20 pyung housing, deficiency and bath unit type were popular ones. 3) Bath unit type was the most generalized one in 21-30 pyung. 4) Bath unit type and over unit type were generally equipped in 31-34 pyung housing. 3. The size of bathroom was ranged from 0.7 pyung to 2.0 pyung, and the ratio of it was 7.5- 12%.

E.faecium MJ-14가 생산하는 박테리오신 30 BU/ML 처리에 의해 L. monocytogepes 균수는 0.6 log unit 감소 되었으나, 박테리오신 (30 BU/mL $65^{\circ}C$, 5분간 가열처리와 병용한 경우에는 약 2.7 log unit가 감소하였다. 박테리오신 30 BU/mL와 itric acid혹은 acetic acid $0.5\%$를 병용 처리한 경우에는 24시간 만에 초기균수가 각각 약 2 log unit와 3 log unit감소하였다. 박테리오신 30 BU/mL와 NaCl $8\%$를 병용 처리했을 때에는 박테리오신 단독 처리구보다 약 1 log unit더 감소되었다. 또한, 박테리오신 30 BU/mL단독 처리했을 때에 비해 sodium benzoate $500{\mu}g/mL$혹은 sodium lactate $1000{\mu}g/mL$와 각각 병용 처리하면 2 log unit가 더 감소되었으며, sodium nitrate $100{\mu}g/mL$와 potassium nitrate $100{\mu}g/mL$와의 병용 처리한 경우 박테리오신 단독 처리구에 비해 각각 3.5 log unit와 2 log unit이상 더 감소하였다. 한편, 탈지유에 E. faecium MJ-14의 박테리오신 300 BU/mL을 첨가한 경우 $4^{\circ}C$에서 24시간 만에 L. monocytogenes의 균수는 대조구에 비해 각각 약 1.5 log unit감소되었으며,돈육에 첨가한 경우 $-20^{\circ}C$에서 7일간 만에 대조구보다 약 2 log unit의 감소효과가 나타났다.

To investigate the inhibitory activity of 2-hydroxy-3-amino-4-phenylbutyrate-harboring aminopeptidase N inhibitors, p-nitro-AHPA-peptide derivatives (1 and 2) and an AHPA-peptide derivative (3) were synthesized by chain elongation from C-terminal end using DCC/HOBt as a coupling reagent. The peptides $1{\sim}3$ exerted strong inhibitory activities against aminopeptidase N with $IC_{50}$ values of 1.8, 7.3 and $24.0\;{\mu}g/ml$, respectively, and cytotoxicity on cancer cell lines in vitro.

부동소수점 시스템은 IEEE754 표준을 따른다. 부동소수점 방식의 가산기를 2의 보수를 사용하지 않고 1의 보수를 사용함으로서 간단히 나타낼 수 있다. 즉 이 시스템은 단지 반전을 함으로서 간단하고 빠른 연산을 수행할 수 있도록 하였다. 새롭게 설계된 가산기의 연산속도 향상을 위해 53bit의 캐리 선택 가산기를 사용하였다. 본 논문에서는 연산속도 향상을 위한 고성능의 효율적인 마이크로프로세서 시스템을 위한 부동소수점 가산 장치를 설계하였다.

In the course of searching for PAF receptor antagonists, pregomisin (1) and chamigrenal (2) were isolated from the fruits of Schizandra chinensis Baill by the bioactivity-guided isolation. Both compounds showed PAF antagonistic activity and the $IC_{50}$ values were $4.8{\times}10^{-5} M and 1.2{\times}10^{-4}M,$ respectively. In addition, the $^{13}C$ NMR assignments of 1 and 2 using DEPT, HMQC, COLOC and HMBC were reported for the first time.

한반도 동해 중부 해안에 위치한 강원도 고성군 문암리 신석기 유적지의 퇴적층의 퇴적환경은 퇴적물의 입도 특성과 광물 조성에 의하여 세 개의 퇴적층서 단위(Unit)로 구분되었다. 최하위 퇴적 층서 단위인 Uint 3은 하부의 사질층(S)과 상부의 니사질층(mS)으로 세분된다. 이 퇴적층은 해안 사구 모래가 퇴적된 후, 토양화 과정에 의해 소량의 니질(mud)을 함유하는 것으로 해석된다. Unit 3을 피복하는 Unit 2는 신석기 유물이 출토되며, 사층리 구조를 보이는 퇴적층으로 다시 하부의 니사질층(mS)과 상부의 사질층(S)으로 구분된다. 전체적으로 Unit 2 퇴적층은 해빈으로부터 바람에 의해 운반ㆍ퇴적된 전형적인 해안 사구(coastal dune) 퇴적층으로 해석된다. 최상위 퇴적층서 단위인 Unit 1은 역사질층(gS)으로 잔자갈이 함유되어 하부의 퇴적층보다 조립하며, 분급도 불량하다. 이 퇴적층은 해안사구 층으로 현재의 지표 유수와 식물의 영향을 받아 토양화 과정을 나타내는 것으로 해석된다. 이 문암리 유적지 사구층의 형성 연대는 기존의 해수면 변동 연구와 신석기 유물의 연대 분석 결과로 미루어 보아 현세 중기(middle Holocene, 약 7,800∼6,500 yr BP) 전후인 것으로 해석된다.

The asialoglycoprotein receptor (ASGPR) was the first described mammalian lectin that mediates the specific binding and internalization of galactose/N-acetylgalactosamine-terminating glycoproteins by hepatic parenchymal cells. H1 and H2 are known as essential subunits of the functional ASGPR. There were close similarities in ASGPR H2 subunits between cultured cell line HepG2 and normal human liver cells including identical sequences at both termini. It was therefore expected that there may be some similarities between the subunits from normal liver cells and fetal liver cells. The two subunits of human fetal liver ASGPR. designated FL-H1 and FL-H2. were cloned from cDNA library by peR and the sequences were compared with the known HI and H2 sequences of HepG2, and the H1 sequence of nornal human liver cells. The results showed that FL-H1 was identical to H1 of HepG2. Whereas FL-H2 contains a 15-bp miniexon, but missing 57-bp at the near upstream from the membrane-spanning domain compared to H2 of HepG2 and normal human liver cells indicating that FL-H2 resulted from a differential splicing compared to HepG2 and normal liver cells.

This study investigated a process to estimate the need for nursing staff on the basis of a patient elassification system and the required care needs and activities. The investigation was carried out in the following four steps. Step 1. Patients were classified according to the amount of nursing care need on each shift as class I (mildly ill), class II (mederately ill), class III (acutely ill), and class IV (critically ill). Step 2. Measurement of the direct nursing care hours needed for each patient class, and measurement of indirect nursing care hourse and personal time of the nursing staff. Step 3. Calculation of he total nursing workload in a nursing unit. Step 4. Estimation of the nursing staff needed. The investigation was carried out from July 17th to 30th, during 24hours every other day. The subjects were the patients and the nursing staff on two units of Seoul National University Hospital, Korea. Some of the results from the investigation are as follows : 1) Distribution of patient classification On the neuro surgical (N.S.), the distribution was class I, 22 patient, 3, class II, 27 patients, class III, 26 patients, and class IV, 25 patients, For the orthopedic surgical unit(0.5.), it was class I, 43 patients, class II, 43 patients, class III, patients, and class IV, 3 patients. 2) Direct nursing care hours per day On the N.S. unit, 3.2 hours of direct nursing care were needed for class I, 3.9 hours for class II, 5.1 hours of class III, and 6.2 hours for class IV patients, while 2.0 hours for class I, 2.5 hours for class II, 3.5 hours for class III, 5.0 hours class IV patients were needed on the 0.5. units. 3) Analysis of direct nursing care activities Activities were classified into assessment and observation(47%), medication(38.7%), communiontion(5.1%), exercise(2.4%), elimination and irrigation(1.3%), treatmemt(1.1%), hygiene(0.8%), nutrition(0.8%), and hot and cold compress(0.1%). 4) Average hours of indirect nursing care per day. On the N.S. unit 4.2 hours, and on the O.S. unit, 3.5 hours of RN indirect care was needed. 5) The average personal time used by the of nursing staff was 17 minutes for both RNs and nursing assistants in the N.S. unit, and 32 minutes for both RNs and nursing assistants in the O.S. unit. 6) Estimation of nursing staff needed on two specialized units of a university hospital For the N.S. nursing unit of 43 beds, 31 nursing staff would be indicated. For the 0.5. nursing unit of the same number of beds, 19 nursing staff would be indicated.
