여러 사람이 모인 자리에서 심심치 않게 등장하는 화두가 있다. 바로 혈액형이다. 같은 혈액형을 가진 이들이 함께하면 즐거울 것이라는 이상한 믿음이 어떠한 유대관계를 형성하기도 한다. 기억해야 할 것은, 이 혈액형이 맞을 때 사람을 살릴 수도 있다는 것이다. 헌혈은 수혈이 필요한 환자의 생명을 구하는 유일한 수단이다.

2010년까지 중국 본토에서 설비용량은 540GW이상이 될 것이고 발전량은 2조 5천억KWH가 될 것입니다. 세계 널리 알려진 일이지만 양쯔강 유역에서는 3개의 협곡프로젝트가 수행될 것입니다. 3개의 협곡의 설비용량은 18,200MW이며 연간 전기 생산량은 847억 KWH입니다. 이 프로젝트는 2010년까지 완수될 것이고 이로써 전국적인 전력계통시스템이 형성될 것입니다.

Dentinogenesis imperfecta is an inherited disorder of dentin formation, usually exhibiting an autosomal dominant mode of transmission. Type I dentinogenesis imperfecta occurs in patients afflicted with osteogenesis imperfecta. Type II dentinogenesis imperfecta is not associated with osteogenesis imperfecta. Type III dentinogenesis imperfecta (Brandywine type) occurs in a racial isolate area in the state of Maryland. In all three types, teeth of both dentitions are affected with variable clinical appearances. The teeth are opalescent with the color ranging from bluish-gray to brown to yellowish. The dentin is abnormally soft, providing inadequate functional support to the overlying enamel. Although the enamel is normal, it fractures or chips away easily, exposing the occlusal and incisal dentin. The exposed soft dentin often undergoes rapid and severe functional attrition. The teeth exhibit bulb-shaped crowns with constricted cementoenamel junctions and thin roots. The teeth will exhibit varying stages of obliteration of the coronal and root pulpal chambers. The cementum, periodontal ligament and supporting alveolar bone appear normal. The enamel is normal. The mantle dentin remains nearly normal, whereas the remaining dentin is severely dysplastic. The dentinal tubules are disoriented, irregular, widely spaced, and usually larger than normal.

The Purpose of this study was to examine the relationship social capital between self efficacy, and the elderly in participated employment or not. The subjects were 340 elderly people in K, S, Y City in Jeonnam. The statistics used for data analysi were reliability, frequency, percentage, mean, standard deviation, one way ANOVA, correlation and multiple Regression. The results of this study were as follows ; First, the degree of social capital of the elderly in participated employment was 86.5(median value 81), while the degree of social capital who did not participated was 79.7. And the degrees of elderly's self efficacy was 43.2, those data showed higher than median. while the degree of self efficacy who did not participated was 39.1. Second, The elderly's social capital level in participated employment were significantly according to residence, religion, living state, economic state, frequency of employment, health state, spouse, monthly income, and the elderly's self efficacy level in participated employment were significantly according to social capital, economic state, monthly income, spouse, health state, living state, education, religion, frequency of employment, Third, participation on the employment for elderly' social capital was the highest correlation variable in self efficacy. Fourth, The variables that affect the elderly's social capital level were economic state, health state, spouse, religion, which explained about 13% of the total variance. And the variables that affect elderly's self efficacy level norm, economic state, network, participation, residence, health state, trust, age, spouse, which explained about 34% of the total variance.

Bile canaliculi are the structure delivering bile secreted by hepatocytes into the bile passage. Bile secretion is mainly controlled by the cytoskeletal elements, mainly of actin in the microvilli, pericanalicular web. Most studies on the bile secretion have been done in viva situation, however, to control the various parameters in vitro culture system seem to be more useful. To set up an in vitro experimental system, the investigator isolated hepatocytes with an enzymatic method using a mixture of collagenase and hyaluronidase from normal Sprague-Dawley rat liver and cultured. Isolated hepatocytes were round and formed cords in culture. Microvilli covered the whole surface of hepatocytes. Bile canaliculi were formed between hepatocytes and were characterized by the presence of microvilli of various lengths and shapes mainly arising from small surface mounds. Actin filament core in the microvilli and pericanalicular actin web were incomplete. After cytochalasin D treatment, cultured hepatocytes were round but the surface were irregular with surfacen blebs, folds and grooves. Microvilli on the surface were scarce. Bile canaliculi were markedly dilated often with the detached junctional complexes. Bile canaliculi lacks microvilli almost completely and extended into the pericanalirular cytoplasm showing complex vacuolar and tubular structures by transmission electron mciroscopy. Pericanalicular actin web, intermediate filaments were hardly identified. Subsurface actin filaments were scattered scarcely under the cell membranes. These results suggest that hepatocytes isolated from rats can survive and form bile canaliculi in culture and the actin filaments are involved in the formation and/or maintenance of the bile canaliculi.

The effects of plant regulators on direct somatic embryogenesis in liquid culture of Rehmannia glutinosa were investigated and the proper explant for direct somatic embryo formation was studied. Direct somatic embryos were induced from leaf segments culture in the MS liquid medium containing 0.5 mg/l of both IAA and NAA, while IBA of 1.0 mg/l was required for the same effect. Many somatic embryos were directly formed at the concentration of 2.0 mg/l cytokinin such as BA, kinetin and zeatin, but somatic embryogenesis was relatively poor at above or below this level. Relatively more somatic embryos were induced in the combination of 1.0mg/l IAA and 2.0mg/l zeatin. Formation of somatic embryos begun after 6 weeks on stem segments, while 7 weeks both on petiole and leaf. However, overall production of somatic embryos after 8 weeks was higher in leaf segment than that of stem segment.
