Two kinds of enzymes solution, capable of degrading the cell wall of red alga Porphyra psuedolinearis Ueda, were prepared from the abalone acetone powder and alkaline hemicellulase. Selected vegetative fronds(3cm) were washed thoroughly in sterile seawater. These blade pieces was kept overnight in an antibiotic solution, and used for isolated protoplast. The vegetative tissue was pretreated, cut into small pieces and soaked in 10% papain solution, and then the small pieces of tissue were incubated in tube containing 5ml of 10% abalone aceton powder solution and 0.01% alkaline hemicellulase solution(MES buffer and pH 6.0) respectively. Protoplasts were removed from the enzyme solution by filtration through a 40μm nylon mesh followed by centrifuge. Yields of protoplasts was higher in alkalin hemicellulase solution(6.0×106/0.1g) than in abalone acetone powder solution(5.4×105/0.1g).

In this study, a directional coupler which is fabricated on X-cut LiNbO₃ substrate by using proton exchange method is described. It is found that the directional coupler waveguide varied widely with controlling diffusion process. On the other hand, the on-off state of modulator is performed by annealing process and self-aligned electrodes are used in fabricating the direction coupler. As a results, the direction coupler has good characteristics : the measured on-off switching voltage of about 2.7-3V.

This study has some useful information about washout water from the small scale incinerator, installed in Chosun university. The results are as follows; 1. The concentration of SS has 65.2㎎/ℓ after being screened by micro strainer. 2. Alum(10% as Al_(2)O_(3) : 3㎖/ℓA-601P 4㎖/ℓ was added in pH 7.5 for coagulating screened washout water. The removal rate after carrying chemical coagulation turned out to be 85.8% in SS, 45.4% in CODMn, 64.5% in BOD with concentration 9.1㎎/ℓ ,93.5㎎/ℓ and 134.8㎎/ℓ respectively. Some heavy metals were also analysed and their removal efficiency was higher than expected as below : Pb, Zn, and Fe was determined as 0.76㎎/ℓ , l.06㎎/ℓ, 2.63㎎/ℓ with removal rate of 93.7%, 86.6% and 80.6% in each item, respectively. 3. The optimum HRT for sample which is mixed with coagulated washout water and screened sewage wastewater on HBC-briquet ash complicative media was 13.4hr. Mixed sample with different rate like 1 : 1(ratio of chemically coagulated water to sewage wastewater on a half and half bases) obtained from biomembrane reactor with 13.4hr retention time, was determined value as 35㎎/ℓ (38.6% removal rate), 28.3㎎/ℓ (81.3% removal rate) and 51.7㎎/ℓ (75.7% removal rate) with respect with SS, BOD and CODMn, respectively.

Background and objectives: High-resolution endoscopes and the advent of endoscopic instruments for sinus surgery currently provide surgeons with excellent endonasal visualization and access to the medial orbital walls. The purpose of this study was to demonstrate the reduction of medial orbital wall fractures through an endonasal endoscopic approach that allows the repair of the medial orbital wall fractures without an external incision. Materials and Method : This study was a retrospective analysis of 16 patients who underwent surgical repair of medial orbital wall fractures from March of 2000 to June of 2002. The 11 male and five female patients ranged in age from 15 to 54 years (mean, 28.8 years). These patients had undergone primary reduction of medial orbital wall fractures and were observed for at least 2 months after surgery. Result: All of 16 patients showed a complete improvement of their preoperative symptoms. There were no intraoperative or postoperative complications. Conclusion: Endoscopic reduction of medial orbit wall fracture using an endonasal approach seems to produce good results and definite cosmetic advantages.

Uterine cervical cancer is the most common cancer of woman in Korea. To understand which oncogenes are involved in squamous cell carcinomas of the uterine cervix, author examined nine human tissues of squamous cell carcinomas of the uterine cervix using Southern blotting techniques for five known oncogenes (H-ras, v-mos, erbB2, c-myc, K-ras). One of the nine tumors demonstrated a rearrangement of the H-ras oncogene. And amplification of v-mos was found in three tumors. The other oncogenes(erbB2, c-myc and K-ras) were the same pattern with the control. It is presumed that rearrangement of H-ras and amplifications of v-mos may be concerned to oncogenesis of squamous cell carcinomas of uterine cervix.

In 2018 2nd semester, 134 students who were attending the ‘A Day of Busan’ were asked to take this survey. Among them, 78 students were from Busan. This paper analyzed these 78 students. According to the respondents' grades, 52.6% of the respondents were in the first grade, slightly more than half, and the second was 33.3%. It can be seen that the 'A Day of Busan' course are mainly in interested in lower grades. According to the year of birth of the respondents, the birth rate in 1999 was 43.6% of the total, including one missing value. In this questionnaire, we surveyed and analyzed the religion of the students, the parent's home, the typical food of Busan, representative places in Busan, and the personality, strengths and weaknesses of Busan people. We also surveyed students' lives, for example, the number of participating in Pusan International Film Festival, the number of visits to professional baseball games, the number of overseas trips, using mobile phones time per day, the number of close friends, sleeping hours. Also we surveyed the population size of Busan. The proportion of students who replied that population size is less than the actual population of 3.45 million in Busan was similar to that of students who replied that it is more. 2018년도 2학기 ‘부산의 하루’ 수강생 가운데 부산출신 학생 78명을 대상으로 분석을 하였다. 응답자의 학년별 구성을 보면 1학년이 52.6%로 절반을 조금 넘고, 그 다음은 2학년으로 33.3%이었다. ‘부산의 하루’ 과목은 주로 저학년이 수강하는 것을 알 수 있다. 응답자의 출생연도를 보면 1999년 출생자가 결측값 1명을 포함한 전체에서 43.6%를 점하여 가장 높은 비율을 보였다. 응답학생 78명의 종교를 보면 무교가 61.5%로 압도적인 비중을 점하고 있다. 그 다음으로 불교가 20.5%, 개신교가 12.8%, 가톨릭이 3.8% 그리고 기타종교가 1.3%였다. 아버지의 고향은 부산이 53.8%로 절반을 넘으며, 그 다음은 경남으로 24.4%였다. 부산과 경남을 합하면 78.2%로 절대적인 비중을 점하고 있다. 어머니의 고향은 부산이 56.4%, 경남이 11.5%로 부산과 경남을 합하면 67.9%였다. 부산의 대표음식으로는 돼지국밥이 36.2%, 21.2%의 어묵, 15.7%의 밀면, 8.7%의 씨앗호떡, 7.4%의 생선회 순이었다. 타지역에서 오는 친구들에게 보여주고 싶은 곳으로는 광안리가 17.9%, 해운대로 13.1%, 서면으로 10.3였다. 그 다음으로는 롯데야구 6.1%, 광안리불꽃놀이 5.3%, 센텀시티 5.1%, 광안대교 4.9% 순으로 나타나 주로 광안리와 해운대 그리고 서면 쪽으로 쏠리는 경향이 나타났다. 부산에서 새로 생기면 좋은 것에 대한 설문에서는 놀이공원이 13.3%, 워터파크10.8%, 공원 8.7%, 체육관 8.2%, 수목원과 박물관이 각각 5.8%로 나타나 학생들은 놀이시설을 가장 원하고 있었으며 그 다음으로 공원과 체육관을 선호하였다. 부산사람들의 성격에서 좋은 점이 무엇인가에 대해서는 ‘의리있다’가 17.8%로 가장 많았고, 나쁜 성격은 32.5%의 압도적인 비율이 성격이 ‘급하다’로 나타났다. 즐겨마시는 음료에는 커피가 33.3%로 가장 높았고, 그 다음은 26.9%의 콜라였다. 주중 술 마시는 횟수에 대한 설문에는 ‘전혀 마시지 않는다’는 학생이 38.5%로 약 40%에 해당하는 학생이 전혀 술을 마시지 않는 것으로 나타났다. 부산국제영화제에 참여한 횟수, 부산에서 열린 프로야구 경기에 참여한 경험, 해외 여행 횟수에 대한 설문에 대해서는 각각 전체의 64.1%, 35.9%, 33.3%의 학생들이 한번도 없는 것으로 나타났다. 하루 휴대전화 사용시간의 평균은 271분, 친한 친구수의 평균은 13명, 수면시간은 평균은 6.8시간, 한달 용돈은 평균 35만원이었다. 부산의 인구가 얼마나 되겠는가 하는 설문에 대한 응답은 매우 다양하였는데, 2만명에서부터 3,800만명까지 넓은 범위에 걸쳐 분포하였다. 그런데 부산의 실제인구 345만명 선보다 적다고 응답한 학생의 비율이 약 절반이었고 나머지 절반은 그보다 많다고 응답하였다.

데이타흐름/제어흐름 혼합계산 모델을 기초로한 다중스레드 컴퓨터 구조의 동적 캐쉬충전 기법

In most multithreaded, and multithreaded computer architectures, the cache refill has been performed based on the locality of memory references. The scheme, however, would not be effective anymore in the multithreaded architecture because context switching to another one will inevitably require initial cache misses every time the switched context gets mapped onto the target processor for its execution. Under this situation, processor utilization begins to sharply drop and the processing power of the processor gets severly damaged. Unlike von Neumann computational model, in the dataflow/control flow hybrid computational model the information of enabled threads becomes available before their execution. With Based on the prior information enabled threads are to be scheduled and executed by the target processor, keeping the initial cache miss ratio nearly zero. And this result was confirmed by the simulation over several benchmarks running on the MACAW, which has been developing since the very early of 1992 for evaluating architectural features of MPP nodes.
