This study examined temperature effect in egg development and hatching of longtooth grouper, Epinephelus bruneus. Fertilized embryos was not growth after morula stage at $15^{\circ}C$, at 18, 21, 24 and $27^{\circ}C$, the required time from fertilized embryos to hatching were 70 h. 30 min., 44 h. 10 min., 29 h. 10 min. and 24 h. 30 min., respectively. The hatching rates at $24^{\circ}C$ were higher than the other conditions and the hatching was not occurred at $15^{\circ}C$. These results suggest that the water temperature range of egg development and hatching was $18{\sim}27^{\circ}C$. 이 연구는 실내 사육수조에서 자연산란 후 수정된 난을 대상으로 수온에 따른 난 발생속도와 부화율을 조사하였다. 부화에 이르기까지 각 수온조건에서 소요된 시간은 $15^{\circ}C$에서 상실기 이후 발생이 진행되지 않았고, 18, 21, 24, $27^{\circ}C$에서 각각 70시간 30분, 44시간 10분, 29시간 10분 그리고 24시간 30분이 소요되었다. 부화율은 $15^{\circ}C$에서 0%였고, 18, 21, 24 그리고 $27^{\circ}C$에서 각각 $8.3{\pm}1.2%$, $18.0{\pm}6.2%$, $24.0{\pm}4.0%$ 그리고 $17.0{\pm}7.2%$로 뚜렷한 차이 없이 $24^{\circ}C$에서 다소 높았고 21와 $27^{\circ}C$에서 비슷한 경향이었으며 $18^{\circ}C$에서 가장 낮게 나타났다. 이러한 결과에서 자바리의 난발생 수온범위는 $18{\sim}27^{\circ}C$로 제안된다.

The authors investigated the relation between the disturbance of thought and perception and information processing. particulary memory and discrimination of memory sources. in the schizophrenic patients by using experimental procedures. The author tested 20 schizophrenic patients and 20 normal control subjects who were matched according to age. sex and education. All subjects were given 3 types of material set. The first. experimenter presentation set. were made up of 10 opposite word pairs. The second & third set were 10 cards each. A usual word with a cue letter of an opposite word. They were instructed to imagine only with the second set. and to write the opposite word along the cue letter with the third set. After the response sheets had been collected. they were asked to recall all responses in any order. Next. a new test sheet was given for the recognition & the discrimination of the memory sources. The result of the research were as follow: 1) Free recall; A significant decrease of recall ability was found in the schizophrenic group(3.15 words) as compared with the control group(6.68). 2) Recognition(hit rate); There was no significant difference of recognition ability between the SPR group(23.15) and the control group(23.6). 3) Schizophrenic group had poorer signal sensitivity(d'). 4) SPR group had more difficulty in discriminatng what they had imagined from what they had written. SPR group and control group were not different in discriminating what they had seen. 5) Error bias of the discrimination; Schizophrenic group showed markedly poor performance on the discrimination task. They mistook what they had seen as what they had written. what they had imagined as what they had written, and what they had written as what they had seen.

In this paper we used Support Vector Machines (SVMs) recently proposed as the learning method, one of Artificial Neural Network, to divide continuous speech into phonemes, an initial, medial, and final sound, and then, performed continuous speech recognition from it. Decision boundary of phoneme is determined by algorithm with maximum frequency in a short interval. Recognition process is performed by Continuous Hidden Markov Model(CHMM), and we compared it with another phoneme divided by eye-measurement. From experiment we confirmed that the method, SVMs, we proposed is more effective in an initial sound than Gaussian Mixture Models(GMMs).

강박장애와 감각추구 성향

이민규,박상학 中央醫學社 1991 中央醫學 Vol.56 No.5

The purpose of this study is to investigate the relationship between obsessive-compulsive symptoms and sensation-seeking tendency. The subjects were administered the Korean version of Leyton Obsessional Inventory and Sensation Seeking Scale in group. In correlation analysis, the symptom subscale score in Leyton Obsessional Inventory was correlated negatively with unconventional sensation seeking tendency. And then, Using the Leyton Obsessional Inventory, two groups were identified: obsessional group and nonobsessional control group. The author used discriminant function analysis to seek the discriminant sensation seeking behavior between the obsession group and nonobsessional control group. The results of the correlation analysis and discriminant function analysis were as follow. 1. Degree of obsessive symptom was negatively correlated with unconventional sensation seeking tendency. 2. In discriminant function analysis, there was no significant difference of general sensation seeking tendency between the obsessional group and nonobsessional control group.. 3. Specific sensation seeking behaviors, significantly discriminate two groups are as follow. 1) gambling for money 2) using four-letter-words 3) preplaned trip 4) respect for lawful authority 5) parachute jumping 6) good night of rest 7) sexual experience before marriage 8) enjoy discussions insulting others 9) uncontrollable emotional experience

통합적 워크플로우시스템 구축에 대한 탐색적 연구

요약, 경영환경 변화의 가속화와 고객요구의 다양화로 인해 기업은 경쟁력 향상을 위한 방안으로 기업자원관리, 고객관계관리, 지식경영 등에 대한 연구와 활용이 증가하고 있다. 그러나 이러한 경영기법들의 통합이나 상호작용성에 대한 고려가 부족한 실정이다. 이에 본 연구에서는 기업프로세스적 사고를 중심으로 각각의 경영기법과 애플리케이션들이 서로 연동될 수 있는 통합적 워크를 로우시스템 구축의 필요성과 방법에 대해 논의하고 있다. 워크플로우시스템 중심으로 각 모듈들이 구축된다면 기업프로세스 개선에 있어서 비용과 효과측면에서 보다 나은 성과로 이어질 것으로 기대된다. 또한 TQM의 관점에서 경영환경 및 고객요구의 변화에 따라 지속적 개선이 가능하도록 구축되어야 한다.

In dorsal laminectomy for the surgical treatment of thoracolumbar disc disease in dog, the bur could slip into the vertebral canal. For the decrease of this probability of danger, osteotome was used with instruments such as bur and rongeur in dorsal laminectomy. At thoracic vertebrae (T10-T11) and lumbar vertebrae (L5-L6) area, dorsal laminectomys were performed in a dog. In observation for 3 months after surgery, the dog revealed healthy physical condition. For the confirmation of healing condition at 3 months after dorsal laminectomy, two surgical sites were exposed by incision. Excellent healing response was observed with no adhesion and fibrosis in the vertebral canal.

A Study on Enterprise Architectural Approach in Maturing National e-trade Infrastructure

Hag-Min Kim,Ho Hyung Lee 한국무역학회 2006 國際學術大會 論文集 Vol.2006 No.12

This paper introduces the use of enterprise architecture into national e-trade infrastructure. It is well known that many leading countries including Korea is constructing e-trade platform but many business customers are not fully utilizing its system. Those problems mainly come from the lack of architectural approach in e-trade planning and this results in less user utilization, imbalanced public and private roles, weak communication structures and etc. In addition, there is high possibility of being exposed to low return on investment risk in the future. This paper suggests the use of enterprise architecture (EA) approach in global e-trade infrastructure construction because it has very strong advantages continuously to maximize its benefits and to eliminate the problems and to minimize the risks. The current e-trade promotions activities are investigated and some explanations are given why the low utilization of e-trade is being made in e-trade stakeholders. The values of EA are proposed in the context of global e-trade and organizational maturity is considered. Finally, the future topics for research are suggested.
