This paper is concerned with the influence in the job satisfaction by the organization, the job specialty and the self-devotion in the special duty of private security. Today's society is required more intensive security in the diversity, the complexity and the uncertainty, but the public security service could not supply enough for what the society requires. In this circumstance more specialized and special trained security services are demanded from private security industry. With the concerns, this study is based on actual survey. The study is telling us that there is much relationship in job satisfaction between each element. Which means that 1) there is some different from personality, 2) there is much influence in self-devotion by job specialty, 3) there some effectiveness in job satisfaction by job specialty, 4) there is some influence in job satisfaction by self-devotion, and 5) job satisfaction is affected by job specialty and self-devotion.

It is usual that the medical examination of human body need special knowledpe and equipments. Thus we have to spend Lime and energy on going to special place such as hospital where doctors and equipments are. Which often cause missing a good chance af medical treatment as well as giving us inconvenience. However many simple and convenient equipments were developed for checking our health conditions recently. O-ring test is accepted a3 one of useful methods to examine our heallb conditions. Also the test is recognized as a uscful means to judge, withoul any special equipment and medical knowledge, if some medical substances or foods are beneficial or harmful to our health. However, the judgement may be mcorrect because it depend on doctor's subjective point of view.In this study, we developed an automatic O-ring t a r mach~ne which enable us to check our health conditions objectively and quantitatively. The validity of the idea to develope the machine was proved by experiments.

Independent suspension axle and final reduction gear for special-purpose vehicles such as a armored vehicles are almost imported in Germany etc. so, developing them is necessary to save cost. In severe condition (open fields, water surface driving, obstacle pass), special-purpose vehicles must work well. Drop box, axle and final reduction gear performed static analysis. We know that is possible weight reduction. The purpose of this paper is to find out the optimal shape of final reduction gear's case by means of response surface methodology. The response surface method is the statistical method which can be applied to the non-sensitivity based optimization. The response surface which is constructed by the least square method contains only the polynomial terms so that the global maximum and minimum points are easily obtained.

Bulk-type dryers which are widely used for drying special agricultural products such as tobaco leaf, red pepper, mushroom, ginseng, medicinal herb, etc, began to be distributed on a full scale since 1980 and the total number of dryers introduced to farms reached to about 36,600 units as of the end of 1986. In this study a survery was carried on the farmers cultivating special crops, dryer manufacturers and related administrative institutes and associations by means of on-the-spot investigation, mail or interview to collect data on scales and patterns of farming, utilization of bulk-type dryers, production and price streams of the special crops etc. Based on the analysis of the data surveyed predictions were made for the total demand on the bulk-type dryers and for annual demand over five-year span.

Fire safety systems in large buildings are likely to be complex and may be designed independently of other systems. This means that the interactions and interfaces between the fire safety systems and between the environmental control systems and the fire safety systems may not be carried out properly. Many large, recent buildings have many technological component systems that are used for the control of the environment within the building. Because of the "special" nature of the fire safety systems there is little consideration is given to the possibility systems with a dual function. However, many of the functions of fire safety systems are extensions of systems that provide the day to day control over the internal environment. The present world-wide trend towards the establishment of performance codes, and regulations, will enable the functional design of all systems and thereby allow closer integration of the "ordinary" and "special" systems. Some aspects of the functional and performance characteristics of systems in buildings are introduced and discussed. Special reference is made to the contributions of the systems to the minimisation of fire damage.e minimisation of fire damage.

동영상의 출현 이래로 전자 영상 미디어의 보급은 정보의 확산 속도와 범위를 고속화, 대중화시키면서 새로운 영상 환경을 구축하고 있다. 최근에는 아날로그가 갖은 화질에 대한 문제점을 해결할 디지털 영상 기술이 발달함에 따라 본 논문은 이와 같이 컴퓨터를 이용한 디지털 영상 환경에 있어, 디지털 편집과 특수효과 사례에 관한 고찰이라는 측면에서 연구를 시작하였다. 본 논문에서는 영상이 오늘날에 이르기까지의 개념을 재정립하고 영상에 있어서 아날로그와 디지털 기술에 대한 차이점을 분석해 보았다. 그리고 디지털 영상 편집에 대한 특성 및 기술을 바탕으로 국내에서 현재 활용되고 있는 디지털 방식을 이용한 특수효과를 TV광고에서 찾아 분야별로 통계를 내고 분석하였다. 그 결과를 보면, 광고에 있어서 특수효과를 사용하지 않고서는 효과적인 정보전달에 많은 제약을 받고 있었다. 손쉽게 효과를 낼 수 있는 2D의 특수효과가 주로 많이 사용되고 있으며, 2D에 비해 노력과 비용이 많이 드는 3D 기법이나 모션컴트를 카메라 등도 여러 방면으로 시도되고 잇었다. 앞으로는 TV 뿐 아니라, VR을 이용한 가상광고나 인터넷을 공간에서의 동영상 광고에 대한 대처도 있어야 할 것이다.

This paper classified the articles of special needs dentistry(SND) published in Korean medical database according to thematic distribution and chronological change to assess recent academic trends and indicate the direction of study in the future. We selected articles in 17 dental journals registered with the Korea Research Foundation This study found that the total number of articles of SND was 292 in 17 journals from 1973 to 2012. The biggest number of articles of SND was published in the journal of the Korean Academy of Pediatric Dentistry, which means pediatric dentists contribute to dental treatment of people who need special care. According to growing number of people with disabilities, the number of articles related in SND has been increased since 2000. Also, the aged and children as well as people with disabilities fit into the category of SND and the scope of SND has been enlarged. So dentists should concern and study more about SND in the future.
