Artificial intelligence (AI) is software that learns large amounts of data and provides the desired results for certain patterns. In other words, learning a large amount of data is very important, and the role of memory in terms of computing systems is important. Massive data means wider bandwidth, and the design of the memory system that can provide it becomes even more important. Providing wide bandwidth in AI systems is also related to power consumption. AlphaGo, for example, consumes 170 kW of power using 1202 CPUs and 176 GPUs. Since more than 50% of the consumption of memory is usually used by system chips, a lot of investment is being made in memory technology for AI chips. MRAM, PRAM, ReRAM and Hybrid RAM are mainly studied. This study presents various memory technologies that are being studied in artificial intelligence chip design. Especially, MRAM and PRAM are commerciallized for the next generation memory. They have two significant advantages that are ultra low power consumption and nearly zero leakage power. This paper describes a comparative analysis of the four representative new memory technologies.

This study attemped to identify the desirable early childhood education and investigate the current situation of the child care centers. The survey was conducted by means of interviews or mailing method using the structured questionnaire. The sample size was 176 teachers in child care centers in Pusan. The questionnaire was built on previous studies and bibliographies. The results were as follows; (1) Most of the teachers were unqualified and under 30 years of age. (2) The facilities and the equipments in the child care centers were insufficient for children's development. (3)The nutritional knowledge of the teachers were far short and the emergency discipline was seldom carried out. (4) No additional efforts were made for the parent -education. It is required to increase the facilities & the equipments for children's development. It appears that re-education of teachers must be carried out in a near future prior to child educaion.

The nucleotide sequence of a Korea isolate of broad bean wilt favavirus from Rehmannia glutinosa Lib., designated BBWV-RE, was determined. Direct amino acid sequencing of the virus coat proteins suggests that a comparison of several favaviruses in terms of nucleotide sequence and amino acid sequences showed that BBWV-2 isolates display high sequence identity. The small coat protein genes of RNA-2 were also determined for three other Japanese isolates(E, L, and 1-2) and two ATCC isolates(PV132 and PV176) of BBWV. the CP sequence suggested distinct evolution lineages. Serotype 2 favaviruses are more prevalent in Asia, Australia and North America, Wheres serotype 1 is more prevalent in europe.(중략)

The Evolution of Workflow Managment consists of rhe automation of business procedures or "workflows" during which documents, information or tasks are passed from one participant to another in a way that is governed by rules or procedures. Workflow technologies have evolved from image management system, document management system, relational or object database systems, and electronic mail system. Workflow Management system has the benefits to improve better efficiency, process control,flexibility, business process. Automation of many business processes results in the elimination standdardizing working methods. Consistency in the processes leads to greater predictability in levels of response to customers and software control over processes enables their re-design in line with changing business needs, In this present study, we implement Electronic Approval System which is a kind of Workflow Management system using static and dynamic flow control information on the web environment.

본 논문에서는 n-best 리랭킹을 이용한 한-영 통계적 음성 번역 시스템에 대해 논하고 있다. 보통의 음성 번역 시스템은 음성 인식 시스템, 자동 번역 시스템, 음성 합성 시스템이 순차적으로 결합되어 있다. 하지만 본 시스템은 음성 인식 오류에 보다 강인한 시스템을 만들기 위해 음성 인식 시스템으로부터 n-best 인식 문장을 추출하여 번역 결과와 함께 리랭킹의 과정을 거친다. 자동 번역 시스템으로 구절기반 통계적 자동 번역 모델을 사용하여, 음성 인식기의 발음 모델에서 기본 단어 단위와 맞추어 번역 모델과 언어 모델을 훈련시킴으로써 음성 번역 시스템에서 형태소 분석기를 제거할 수 있다. 또한 음성 인식 시스템에서 상황 별로 언어 모델을 분리하여 처리함으로써 자동 번역 시스템에 비해 부족한 음성 인식 시스템의 처리 범위를 보완할 수 있었다.

A comparative study between commercially available mycobacteria growth indicator tubes (MGIT) in the BACTEC MGIT 960 System and the conventional Ogawa media was carried out to assess the effectiveness of the re-decontaminating process for the recovery of mycobacteria. Processed specimens with 5% sodium hydroxide and 0.5% N-acetyl-L-cysteine were inoculated into MGIT and Ogawa media. The acid fast bacilli (AFB) recovered from the cultures were identified using a mycobacterium tuberculosis (TB) antigen kit. If contaminants were observed in the MGIT tubes within five days, a decontaminating process was repeated. A total of 1,190 out of 4,790 (24.8%) specimens showed positive results using the BACTEC MGIT 960 system. Among them, 278 specimens were reprocessed. When the MGIT and Ogawa results were compared, it showed discordant results (weighted kappa value: 0.283). One TB and 10 nontuberculous mycobacteria (NTM) were newly detected in MGIT only. The likely benefit of the re-decontaminating process is the detection of additional mycobacteria that could not be detected without a re-decontaminating process despite being small in number. In addition to the combination of MGIT and Ogawa, the re-decontaminating process is recommended in the case of contaminations to recover mycobacteria.

This study is implemented in the Department of Emergency Medical Technology of the Cheju Halla College in to evaluate behavioral changes in the recognition of the importance of the first aid, coping ability in the field, and competence of the first aid skills after taking the in-service program. The in-service program was hold from December 14 to December 22, 1998 under the title of "1998 First Aid and Emergency Rescue Training" for 176 drivers. The Questionnaire was distributed to 176 drivers, among them, 88 drivers took in-service program and 88 ones did not. After the data analysis, following conclusions we re made. 1. There are no significant statistical differences among demographic factors such as the level of education, age, career, and marital state of the subjects in the recognition of the importance of the first aid and competence of the first aid skills. 2. The drivers, who were the in-service program, significantly higher score in educated in represented all the area of recognition of the importance of first aid than non-educated drivers. 3. The drivers, who were educated in the in-service program, showed also significantly high score in competence of the first aid skills. According to the conclusions, there were significant change made In the recognition of the importance of the first aid and competence of the first aid skills after the in-service program. Therefore, nationwide emergency training program should be considered to improve emergency care ability of the nation.

This study was carried out to establish clipping interval of Pennisetum orientale (PO) and Panicum antidotale (PA) to get maximum biomass production with optimal nutritional value for Nili buffaloes. Two clipping intervals i.e. $CI_1$, and $CI_2$ (clipped after every one and two months, respectively) were studied for both grasses. The data on various parameters were compared with PO and PA each clipped at 4 months of age (control). Leaf to stem ratio in both PO and PA declined with increasing clipping interval. Concentration of dry matter (DM) and organic matter (OM) increased (p<0.05) whereas crude protein contents decreased with increasing clipping interval in both grasses. Crude protein and dry herbage yields in PO and PA increased (p<0.05) with increasing clipping interval. The DM and neutral detergent fiber (NDF) digestibilities of PO and PA in ruminally cannulated buffalo bulls decreased (p<0.05) due to more lignification with increasing clipping interval. Ruminal extent of digestion, rate of disappearance of DM and neutral detergent fiber of PO and PA decreased in buffaloes while ruminal lag time of these nutrients increased significantly (p<0.05) with increasing clipping interval. The results from the study imply that two month clipping interval for both PO and PA grasses favored higher biomass with greater nutritional value for Nili buffaloes and sustained grass vigor.
