Recently, interest and necessity for the insect industry has been increasing. Insects, which are referred to as the second food, are being used in various fields. Interest in mass production of insects has been increasing in various fields, and the need for research on environmental analysis for them is also increasing. In some countries in other developed countries, automated breeding systems have been developed that incorporate IoT. However, it is limited to be applied to many kinds of insects, and the price is so expensive that it has not been utilized in farm households. Therefore, we have carried out a study to make an optimal system that can be used practically in a farmhouse. Protaetia brevitarsis used for medicinal and edible purposes. It automatically checks the moisture of sawdust medium, which has the greatest influence on the environment of the slugs, which is the third larva of the grasshopper, and informs the result through the LED. It is applied to the environment to create an optimal breeding environment. I want to make it.

This study attempts to understand women's underwear culture in the Later Chosun Dynasty, by investigating the kinds and constructions of them, which formed bulky and puffed silhouette of the lower half of the body. In the middle 17th century in Chosun, Confucianism settled down as fundamental idea of society, while whole country achieved considerable economic growth. As a result for upperclass women, female virtues was demanded more than any other period in Chosun. On the other hand, lower-class women including Kisaengs, had more freedom on their clothing behaviors. According to the literature on women's dress institutions and restrictions of the extravagance, the use of kinds of high-quality silk and false hair was criticized, compared to women's clothes in China. From this, one can see the luxury and affluence of women's clothes at that time, which also reflected in luxurious underclothes. Also, the movement of class, by economic development, led to changes in the costumes of middle-to-lower class women, relaxing restrictions on clothes. Underclothes included Bosomband(가슴띠; long sashes for bosom to wrap), Sokjucksam(속적삼), and Sokchogori(속저고리; Korean blouse, worn under the chogori) for upper garment, and Darisokkok(다리속곳; basic underwear like the panty), Soksokkot(속속곳; underwear paji to be wide of hem), Sokpaji(속바지;trouser front and back opening), Tansokkok(단속곳; large size underwear like Soksokkot), Noronpaji(너른바지; paji like the skirt or paji bulky than tansokkot,), Mujigi무지기; tiered skirt for underwear), and Daeshumchi'ma(대슘치마; Korean underskirt, shape hem as a pad into form) for lower clothes.

This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 ischemic stroke patients. The central motor conduction time (CMCT) was represented by the difference of latency to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.

광대역 네트워크의 보급과 더불어, 많은 인터넷 사용자의 꾸준한 증가를 통해 국내의 인터넷 환경은 세계적으로도 상당한 규모가 되었다. 이러한 급격한 인터넷의 증가와 비례해서, 이의 결함을 이용한 해킹 건수가 급격히 증가하고 있다. 과거 서버환경에 대한 해킹시도에서 초고속 네트워크환경의 구성원인 개인 클라이언트 시스템에 대한 바이러스, 해킹 등을 이용한 불법적인 공격이 증가하고 있다. 또한, 상대적으로 보안에 무지한 일반 개인 사용자들을 위협하는 비정상적인 악성코드들이 쉽게 접촉할 수 있는 인터넷 환경에 유보되고 있고, 날로 전문화되고, 지능화된 악성코드 기법이 개발되고 있으나, 이에 대한 보안기술이 적절하게 대응하지 못하고 있는 실정이다. 따라서, 악성 코드 대응을 위해서 악성코드기법에 대한 계속적인 분석과 이에 적절한 대응이 필요하다.

인터넷 보급률이 증가 하면서 순기능에 이어 역기능이 보이기 시작하였다. 그중 우리나라 모든 부모들에게 경종을 울리는 것이 청소년의 게임중독일 것이다. 인터넷은 정보사회를 앞서 나가기 위한 최첨단 기술이자 무기로만 여겨왔던 컴퓨터와 인터넷이 자녀 교육에 도움이 되는 중요한 교구라고 믿던 부모는 시간이나 때우고 게임이나 하는 심지어 밤을 새우는 인터넷의 문제의 심각성을 깨달았기 때문에 무지에서 무조건적으로 게임은 안된다는 결론을 내리면서 청소년들은 어디에도 도움을 청할 곳이 없어 방황하게 되는 것이다. 본 논문에서는 국내외 게임중독 예방 사이트 운영 실태를 파악하고 유료 상담을 받기 어려운 청소년이 쉽게 게임중독에 예방 및 무료 상담할 수 있는 사이트를 분석 후 대응 방안을 제시하고자 한다.

Foreign bodies in esophagus occur unexpectedly in environment, and in most cases they get removed without delay. However, because of patron's ignorance, patient's age and lack of physician's eagerness in examination, the possible presence of the foreign body is overlooked. Recently the authors had experienced a case (5 months aged male infant) of the foreign body which had been lodged at a level of the second esophageal constriction portion for 2 months.

This study was performed to show change of fat-free mass(FFM), representing mostly the muscle mass change, and muscle strength with increasing age, and relationship between dietary, exercise behaviors and FFM in healthy middle-and old aged women who are of age over 55 years. The FFM and correspondingly hand grip strength showed significant positive correlation with age. But concentration of serum albumin showed no significant relationship with age. The subjects were categorized into groups according to FFM tertile. The anthropometry such as weight, BMI, fat mass, circumferences of waist and hip, WHR, and hand grip strength decreased significantly in the lowest FFM group. But the albumin level showed no change according to FFM level. The FFM showed significant correlation with nutrient intakes such as energy, carbohydrate, protein, Fe, P, Ca. No association, however, was shown with exercise behavior probably because of no case with resistance exercise habits. The variance of FFM was explained 55.2% by height and carbohydrate intake. The variance of height-adjusted FFM could be explained only 16.2% by intake amount of carbohydrate. In conclusion, the decrease of FFM may cause to reduce muscle strength in female elderly. The increasing nutrient intakes were associated with the increased FFM and may protect from risk of sarcopenia. However, only the carbohydrate intake could influence independently the FFM in middle- and old-aged women. The FFM has no association with endurance exercise habits.

This paper describes structural optimization of optical fiber-wound mandrel hydrophones with Finite Element Method (FEM). The hydrophone is supposed to have operation frequency range of up to 10 kHz and show omni-directional sensitivity pattern at 5 kHz. Studied parameters are mandrel geometry, molding thickness, and material properties of constitutional parts of the hydrophone. Theoretical calculation result shows that pressure sensitivity of the hydrophone increased as either mandrel length or molding thickness gets larger. Also higher pressure sensitivity requires a mandrel or molding material with relatively low Youngs modulus or Poissons ratio. Hydrophone bandwidth increases either as the mandrel length becomes shorter or as the mandrel becomes harder. The omni-directional characteristic is improved as the mandrel length becomes shorter, at 5 kHz. With the above results, we determine the structure of an optical fiber-wound mandrel hydrophone which has the pressure sensitivity of $30 {\times} 10_{-7}$ Rad./Pa, operation frequency range of up to 10 kHz, and shows omni-directional sensitivity pattern at 5 kHz.
