The prospects for Korea's venture capital(VC) sector are promising because it holds the key to providing a new vitality to the Korean economy. The venture capitalists'(VCs) decision-making process has received tremendous attention in Korea. One critical aspect of the VC process is the screening decision. This study looks at how Korean VCs select in their screening decision criteria. The experiment is administered on 50 Korean VCs. The results that Korean VCs are very intent on the factors in leadership ability of entrepreneurs and market growth when screening investments. Leadership ability and market growth are the top two criteria among eight criteria. But previous start-up experiences of entrepreneurs is less important to them. The results of this study can be used to build decision aids that can improve VC decision-making. And this study also demonstrates the practical basis that decision models provide to the VC decision.

The aim of this in vitro study was to analyze the composition of human tooth enamel in terms of there components, Ca, P, and F after demineralization and remineralization in acid buffer solution. A total of 8 human premolars without any defects and cracks were selected and buccal and lingual sides of the teeth were cleaned with an ultrasonic device and pumice without fluoride. 5×5mm windows were opened, and other areas were completely covered with 3-coats of nail varnish to prevent from being in contact with demineralized and remineralized solutions. After demineralization process, each tooth was sectioned into two slices, highly polished one of them withγ-alumina, and then analyzed the composition of the demineralized tooth with EPMA(electron probe micro-analyzer) . The ocher slices were put into the remineralized solution for 10 days, polished, and analyzed in the same manner. These data were statistically analyzed with one sample t-test(p<0.05) . The results were as follows. 1. Normal tooth enamel consists of 49.76% Ca, 39.80% P, and 0.28% F. 2. After demineralization, percentage of Ca and P ratio were decreased by about 5.57 and 5.07% respectively. Percentage of F ratio was also decreased by about 0.01%, which was not statistically significant. 3. After remineralization, percentage of Ca, P increased about by 4.47 and 4.35% respectively. Percentage of F decreased by about 0.01%, which was not statistically significant. In conclusion, remineralized solution used in our study has the potential to induce the uptake the Ca and P into the pore sites of the demineralized enamel. But, in the oral cavity, there were rapid temperature change, organic matrix that inhibits the movement of the ions, and limitation of continuous contact with this remineralized solution. Therefore, further in vivo study is necessary.

1920년에 발표된 페르디낭 드 소쉬르 Ferdinand de Saussure의 『일반 언어학의 기본물음들 Grundfragen der allgemeinen Sprachwissenschaft』은 학문론 Wissenschaftstheorie에 있어서 하나의 중요한 획을 긋는 내용을 담고 있다. 그것은 언어학이란 개별학문의 영역의 한계성을 넘어서 인문과학 전반에 영향을 끼친 구조주의의 담론화와는 다른 성격의 것이다. 그것은 다름이 아니라 학문과 학문의 대상 사이의 일반적인 관계에 대한 진술이다.

A prospective research of 1,573 patients who visited emergency room was completed by the emergency physician of Wonju College of Medicine of Yonsei University, and Youngdong Hospital. This prospective study demonstrate the problems of prehospital emergency care and transfer system of the emergency patient. Among 1,573 patients, 86.9% were admitted to the Emergency room by the non-emergency vehicle such as taxi and bus, and only 13.1% was admitted via ambulance. At the situation of emergency, the most of patients and patient`s families could not call for the help to emergency telemetry center because only 3.1% among total patients knew the emergency call number(Tel. No: 129). Because the emergency delivery system between emergency centers from Level. Ⅰ, Ⅱ to Level Ⅲ was not established yet, only 492 patients(31.3%) were transferred from Level Ⅰ, Ⅱ emergency room to our emergency room to our emergency center but 1081 patients(68.7%) were admitted directly to Level Ⅲ emergency center from emergency fields. Among 1,081 patients who visited Level Ⅲ emergency center directly, only 240 patients(23%) were admitted for further treatment, but in transferred cases(492 patients), 271 patients(55%) were admitted. Especially in the injured patients, severely injured patients(ISS 16) occupied only 6% among 441 patients who visited directly, but it occupied 21% among 150patients who were transferrd from local community hospital. This result means that many non-urgent patients visited Level Ⅲ emergency centers without the previous visiting of Level ⅠⅡ emergency room. This study reveals that EMSS(Emergency Medical Services System) including the telemetry systems must be organized in short-time to reduce the mortality and morbidity of emergency patients. First, the educations about the emergency call system and First Aids to the people must be stsryed initially through the school and mass-media such as television and radio network. Second, emergency delivery system between Level Ⅰ,Ⅱ,Ⅲ emergency center must be organized for the effective and rapid transportaion of acute ill patients.
