본 연구는 자원의 제약이라는 중소기업이 안고 있는 특성을 갖고 있는 벤처기업의 국제화에 영향을 미치는 요인에는 어떤 것이 있는가를 한국의 정보보호 업체들에 대한 실증 조사를 통해서 살펴보았다. 연구 결과에 의하면, 첨단산업에 종사하고 있는 하이테크 벤처기업의 국제화는 경영자의 주관적 상황인식에 의해 영향을 받으며, 해외진출시 경쟁 양상은 자원의 한계로 인해 가격 경쟁 보다는 기술, 품질 경쟁에 의존하는 경향이 있다고 밝혀졌다. 그 외에도 기존의 국제화와 관련된 여러 요인에서 중요한 변수라고 할 수 있는 국제기업의 규모, 시장의 성숙도, 경쟁강도 등과 같은 요인에 대해서도 고찰하여, 자본금 규모와 경쟁의 강도에 대한 경영자의 기대도 영향을 미치는 것을 알 수 있었다. 연구 대상 기업을 정보보호업체로 한정하여 기업 국제화의 영향요인을 살펴봄으로써 산업특성요인을 제거하였으나 표본 수가 적고 대부분의 기업이 아직도 신생기업의 수준을 벗어나지 못하고 있어 실종분석 결과가 만족스럽지는 못하지만 전체적인 방향은 연구 가설에서 크게 벗어나지 않는다고 할 수 있다. 향후 다른 분야의 벤처기업으로 확장하고 기술적 학습, 다양성 및 진출방식 둥과 같은 다양한 변수를 포함시키는 연구로 발전시켜야 할 것이다. This study examines the factors of venture businesses' internationalization. We conduct empirical research on Korean information security industry which has the weaknesses resulting from the lack of resources like many other small-sized enterprises. As an increasing number of new venture firms arc internationalizing their business operations early in their life cycles, the analysis of the international expansion process of small technology-13ase0 firms is getting more important. Results identif4ed in this study suggest that the internationalization of high-tech venture businesses is influenced by the management attitude to the foreign market and they have a tendency to depend on the competition based on technology or product quality rather than price. Analyzing many other variables such as the size of the firm, the maturity of the market and the competition intensity, we found that the variable like the size in terms of capital and the expectation of the management to the competition intensity are also affecting high-tech ventures' going abroad. This finding has the implication that the venture businesses international expansion relate to environmental conditions like the booming of capital market and the specific circumstance of Korean venture industry.

Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

This study was undertaken for the clinical evaluation and statistical analysis on the 38 cases of placenta previa who were admitted and treated from March 1, 1988 to Feb. 28, 1991. The results were as follows : 1. The incidence of placenta previa was one per 53 deliveries or 1.90% 2. There were 57.9 % total placenta previa, 21.1 % partial placenta previa, 13.1 % low-lying placenta previa and 7.9% marginal placenta previa. 3. Placenta previa has occured more often in multipara (63.2%) than primigravida 4. More than one-third (38.8%) cases of placenta previa had delayed admission until labor occured for some time following vaginal spotting has first time been noticed. More instructive prenatal education should be emphasized 5. Lower segment transverse section rate was 63.2%, classical cesarean section rate was 15.8% and cesarean hysterectomy was 9.8%. The rest of them were treated by vaginal deliveries of 5 cases(13.2%) 6. The perinatal loss associated with placenta previa was considered still higher : the premature death was 15.8% and term death was 2.6%. The problem of prevention of prematurity still remains to be studied. 7. There was no maternal mortality in our study

Monoclonal antibody를 이용한 Saliva-check Mutans키트의 타액 Streptococcus mutans검출방법으로서의 활용도와 임상적 우식지수 및 기존의 세균배양방법과의 상관관계를 알아보기 위해 2008년 2월에서 5월 중 평촌키즈웰치과에 내원한 만 2세에서 만 8세 사이의 92명의 아동을 대상으로 Streptococcus mutans 검출검사를 실시하였으며 또한 우식에 영향을 미치는 다른 요인인 치면세균막 pH와 타액완충능력검사를 실시하여 다음과 같은 결론을 얻었다. 1. Saliva-check Mutans 검사결과 양성을 나타낸 아동은 27명으로 29.3%이었고, 음성을 나타낸 아동은 65명으로 70.65%이었다. 우식경험유치면률은 음성 아동 13.89%, 양성 아동 25.23%으로 나타났다. 2. Monoclonal antibody를 이용한 검사방법 인 Saliva- Mutans와 기존의 세균 배양방법인 -SM은 각각 상이한 검사방법을 이용함에도 불구하고 검사결과 높은 상관관계를 보였다(p<0.01). 3. Saliva-check Mutans검사와 치면세균막 pH검사와는 역상관관계를 나타내었으나(p<0.01),타액완충능 검사와는 상관관계가 나타나지 않았다(p>0.05). 이상의 결과로 보았을 때 Monoclonal antibody를 이용한 검사방법인 Saliva-check Mutans는 구강 내 Streptococcus mutans를 측정하는 방법으로 적당하며 또한 검사에 필요한 시간을 대폭 줄일 수 있고 사용방법도 매우 간편하게 개발되어 환자들에게 적용함에 있어 효과적이라고 사료되었다. The purpose of this study was to evaluate the clinical effectiveness of new streptococcus detection system which used monoclonal antibody against Streptococcus mutans. 92 children aged between 2 and 8 were involved in this experiment and their saliva samples were collected for testing. Streptococcus mutans were measured by both monoclonal antibody-based detecting system (Saliva-check Mutans) and dip slide detecting system(Dentocult-SM). The results showed that Saliva-check Mutans levels had a significant correlation with dfs rate of subjects and the two test kits, Saliva-check Mutans and Dentocult-SM were shown to have a good correlation although they were based on different mechanism.

This study was conducted to compare the concentration of sulfur oxides and nitrogen oxides emitted from the household incineration facility in Taegu city before and after the adoption of garbage packing system. Their concentrations were measured by an automatic analyzing equipment(MCS 100) at Sung-Suh household waste incineration facility in Taegu city using the non-dispersion infrared absorption analysis method from January 1 to June 30, 1994 before the adoption of the garbage packing system, and from January 1 to June 30, 1995 after the adoption of the system. The means of daily maximal concentration and daily average concentration of the emitted sulfur oxides were 40.9±23.00ppm and 21.4±6.18ppm in 1994, and 75.7±59.43ppm and 22.0±8.95ppm in 1995, respectively. In 1994, the concentration showed a gradual reduction from January until June, but there was a marked variation in 1995. By the day of the week, both 1994 and 1995 showed the lowest figures on Sundays. In the multi-variable analysis of variance to nitrogen oxides, there was not a noticeable statistical figure by the year and by a day of the week, but there did exist a noteworthy difference among the monthly emission concentrations (p<0.05). The means of daily maximal concentration and daily average concentration of the emitted nitrogen oxides were 175.6±23.82ppm and 122.3±26.92ppm in 1994, and 143.7±16.57ppm and 100.2±25.85ppm in 1995, respectively. By month, the means of its daily average concentration was lowest in June, 1994 at 89.4±26.29ppm and 72.7±31.36ppm in April, 1995. By the day of week, there was not much variation, it was lowest on Saturdays at 116.6±24.74ppm in 1994 and on Wednesdays at 93.4±25.79ppm in 1995. In the result of the multi-variable analysis of variance, it was significant that there was a difference in the nitrogen oxides emission concentration between the by-the-year figure of p<0.05 and by-the-mouth figure of p<0.05. This result suggests that the adoption of garbage packing system may affect the emission concentration of emitted nitrogen oxides from household waste incineration facility.

It has been rapidly given to the importance of the embodiment of the efficient computer systems in university education. Since the recent trend of the adoption of the openess policy in university education systems significantly affects on the realization of the embodiment of the efficient computer systems which is very essential to promote the international competition in many areas of university education. So it is greatly needed that our Soonchunhyang university must have the following principles for the embodiment of the efficient computer systems. (1) It is required that the appropriate computer education and the good quality of research environment must be given. (2) The establishment of the synthetic computer network system for efficient the university administrations is needed. (3) It is needed to establish the computer system for the consideration of the future performance. (4) It is also needed to improve the organization and the administration systems of the university computer center. (5) It is required on the establishment of the local area network(LAN) systems in the Soonchunhyang university, and the LAN must be connected to other outer national and international computer systems. And we propose the following requirement for the establishment of the convienent computer systems in our university and we have been greatly though about the significant change of the environment in university computer system. [1] The subject of the basic computer must become as the required subject for the all students in the curriulum. [2] The new computer systems both in hardware and software must be introduced. [3] It is needed to the change of the present name of the university computer center into the university information and computer center. And its organizations must be furthur developed [4] The training center for the university emploee is also needed. [5] The establishment of the database systems for the automtion of the university administation is needed. [6] It is strongly required on the establishment of the local area network system in the Soonchunhang university to connect the Bitnet and the Internet through the Hankook communication. [7] The computerization for the central library is needed. The indepent local area network system for the library is also needed to establish the own database system. Finally we hope that the LAN will be connected to the national wide library computer system.

상관계수를 이용한 회전 동심원 레티클 탐색기의 반대응능력

홍현기,최종수 중앙대학교 정보통신연구소 1999 정보통신연구소논문집 Vol.1 No.1

적외선 탐색기에 널리 사용되는 레티클 시스템은 시계(field of view ; FOV) 상에 존재하는 표적의 위치를 구하는 대표적인 방법이다. 본 논문에서는 동심원(concentric annular ring) 레티클 탐색기의 표적 추적 성능을 시뮬레이션 할 수 있는 효과적인 툴이 제안된다. 시계상에 섬광탄 등의 대응능력이 존재하는 경우, 표적에 대한 정확한 추적은 매우 어렵게 된다. 이러한 대응능력의 영향을 줄이기 위해 입력 신호와 기준 신호와의 상관 관계를 이용하는 반대응 기법이 제안된다. 구성된 툴 상에서 제안된 방법이 기존 방법에 비해 보다 효과적인 표적 추적 결과를 보임을 확인하였다. Reticle systems. which are widely used in infrared (IR) missile seekers, are considered to be the classical approach for estimating the position of a target in the field of view (FOV). This paper presents an effective simulation tool that gives tracking results of the concentric annular ring reticle seeker. Our simulation model provides tracking results in various cases, and is applicable to the study of the development of the advanced seekers. While false targets such as flares are presented in the FOV, simulation results show that the existing seeker cannot determine a precise target location. In order to decrease the susceptibility to countermeasures such as flares, we propose an efficient counter-countermeasure using the correlated relationship of modulated signals and the references. We have ascertained that the reticle seeker using our technique make more effective target tracking than previous seekers.
