속도제한의 목적은 주어진 도로상황에 따라 차량 흐름의 안전을 위해 안전한 속도로 교통운영적 측면에서 안전한 속도를 제공하는 것이다. 그렇기 때문에 속도제한은 반드시 신중히 검토되야 하며 특히 고속도로 진출입구의 속도제한은 차량의 특성을 고려해야 한다. 고속도로 진출입구에서의 속도제한은 곡선 반경에 따라 변화하는 속도를 고려해야 하며 이러한 과정에서 85 백분위 속도는 중요한 고려 요소가 된다. 교통사고의 대부분이 차량 사이에 속도편차가 원인이라는 점을 감안할 때 제한속도는 차량의 주행특성을 고려하여 설정되어야 한다. 이러한 차원에서 제한속도의 상향 조정 혹은 하향 조정에 의미를 두기보다는 각 도로의 특성에 맞는 속도분포를 충분히 고려해야 한다. 차량의 속도분포를 가장 잘 설명하는 85백분위 속도에 대한 조사 및 추정을 통해 속도차를 줄일 수 있는 방안을 모색해야 한다. 따라서 본 논문에서는 양지, 용인, 청원 인터체인지의 진출구를 대상으로 제한속도 설정 방법론을 제시하여 운영 중인 도로에 대한 제한속도의 조정을 통해 교통사고 위험성을 줄이고 적절한 제한속도를 설정하도록 하였다. 또한 제한속도 표지판을 설치하는 위치에 대한 연구를 통해 적절한 표지판 설치 위치를 찾고자 하였다.

It is necessary to evaluate performances hitherto carried out in the management of Total Maximum Daily Loads (TMDLs) and to set up direction so that this system can be improved continuously in the future. This study was investigated load allocation achievement ratio, water quality goal achievement ratio and interrelation between water quality goal and load allocation for the first period (2004~2010). Load allocation achievement and BOD water quality goal achievement ratio were 50% and 73% in Guem River Basin, respectively. The main reason for excess of load allocation and shortfall of water quality goal were unfulfilled reduction plan and pollution sources increment. Therefore, it is necessary to develop enhanced pollution sources prediction method and make a list realizable reduction plan. 63% of the unit watershed was not interrelation between water quality goal and load allocation. The reason why water quality goal and load allocation had not correlation were water quality of upper unit watershed, increment of inflow quantity, effluent water quality of wastewater treatment plant affected the unit watershed, increment of inner productivity by algae, water quality deterioration during the specific period, river management flow, etc.

The radiopharmaceuticals are routinely injected to blood vessel for acquiring PET image. For this reason, It is imperative that they undergo strict quality control measures. Especially, Sterility test is more important than any other quality control procedures. According to the FDA guideline, It requires filter integrity test used in the processing of sterile solutions. Among several methods, we can decide to use bubble point test. We usually use vented GS-filters (Millipore co., USA) which are sterilizinggrade (0.22 um pore size) and are placed upper site on product vial. After the synthesis of $^{18}F$-FDG, solutions wet the membrane in filter and then go into the product vial. By all synthesis steps have finished, we can observe the presence of the bubbles in the product vial. Since we have started this study, we have never found any bubbles in the product vial. Because the maximum pressure intensity of the filter which has set by manufacturer is up to 5 bars, but helium gas pressure is up to 1 bar in our module system. So, we can make 5 bars pressure using helium gas bombe and increase pressure up to 5 bars step by step. However, it does not happen to anything in vial.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

The purpose of this study is to examine closely the aesthetic characteristics featured in dandy's costume. Dandy was term used on for a man excessively fond of and overly concerned with clothes, exemplified by Beau Brummell, Lord Byron, and count d'Orsay, who greatly in gluenced men's fashions in England and France. In the late eighteenth and early nineteenth century George Brummell, the prototype of the dandy, made upper-class English country clothes, especially riding clothes, into the height of men's fashion in the city. In the early 1800s the alterations he made, particularly with regard to fit and cut, established these as the critical signifiers in men's dress. Brummell's style, particularly for day, was essentially restrained and disciplined, and set a standard for sober discretion, appropriateness and taste which governed men's clothing until well into the twentieth century. The aesthetic characteristics expressed in dandy's dress are the aristocratic superiority of mind, the restrained beauty in absolute simplicity, and the pursuit of the individual beauty. Brummell's kind of dandyism instigated the idea of establishing a new kind of aritocracy, an aritocracy based on talent. Over the years this kind of cultural and social coup has been played out in different ways but has remained, like the twentieth-century concept of the avant-garde, a fundamentally male preserve. He advocated unobtrusive darkblue fitted coats, cream-colored trousers, elaborately tied cravats, absence of showy fabrics or excessive decoration, and impeccable grooming. The status of the perfectly tied cravat as the hallmark of genteel elegance, as the last keystone of Fashion's arch, had been established by Beau Brummell.

Seeing through the reference of literatures ${\ll}$Internal Classic${\gg}$, ${\ll}$Donguibogam${\gg}$ and Master Jisan's theory about Ki-Hyul and Hyul-Ki, the writer came to conclusions as follows. In ${\ll}$Internal Classic${\gg}$ Ki-Hyul is expressed into being orderly and ordinate, but Hyul-Ki is described differently into making Hyul-Ki or operating Hyul-Ki. In ${\ll}$Donguibogam${\gg}$ Ki-Hyul and Hyul-Ki are not distinguished between two things, but Ki-Hyul is mentioned as harmony of Ki-Hyul and Hyul-Ki, and Hyul-Ki as ascending and descending or as deficiency and excess. In Hyungsang medicine the special characters of Ki-Hyul is seized the essence of the meanings from the deflection between left and right, changes of skin, flesh, meridian, muscle and bones. And the distinctive marks of Hyul-Ki is got hold from changes of complexion, many or few hairs, ascending or descending spirits of ears, eyes, mouth and nose. Also Ki-Hyul is recognized by laying stress on rise and fall, after birth, breast, upper limbs, eight extra meridians. And Hyul-Ki is recognized by laying stress on going up and down, the inborn constitution, abdomen, lower limbs, and twelve meridians. Jisan distinguished Ki-Hyul from Hyul-Ki theoretically and he applied the theory to clinical examination proved the facts that the theory and the examination are in accord with each other. This attempts was for the first time in Oriental medicine history and the theory was set up. It is thought that the defects of the theory about Ki-Hyul and Hyul-Ki which Jisan insisted on need much more study from now on.

The purpose of this study is to investigate the effect of shirt color, tie color, tone, perceiver' gender on impression formation by applying tone-in-tone coloration of shirt and necktie: coloration of two colors. This experiment was designed to utilize the $2{\times}6{\times}4{\times}2$ factorial designs. and they are shirt color(red, blue), tie color(red, yellow red, yellow, green, blue, purple), tone(vivid, light, dull, dark), and perceiver' gender(a male, a female). The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 48 upper body photographs which were color outputs by CAD system(4D-box program). The subjects of this research were 288 male and 288 female college students. There were established impression dimension from factor analysis 27 bi-polar adjectives and investigated the effect of interaction between each variable affected impression formations. The items of the adjectives are classified into 4 Impression dimensions: activity, potency, attractiveness, and tenderness. Shirt color, tie color, tone, and perceiver' gender influenced on impression formation. Specially, tie color and tone influenced on the 4 impression dimension greatly by interaction as well as independently. As a result tie is very important clue of impression formation in tone-in-tone coloration of shirt and necktie. Even though tie occupies only a small area in men's clothes it has great effect since it is close to the face.

본 연구는 다단 하이브리드 로켓의 낮은 비추력 성능을 향상시키는 방법으로 AP 첨가 추진제를 제안하고 있다. 추진제에 첨가된 AP 첨가비율 변화에 따라 다단 하이브리드 로켓의 비추력 성능 변화와 연료과농 연소특성 변화를 살펴보았으며, 이때 AP 첨가비율은 하이브리드 로켓의 연소 특징을 유지하기 위해 최대 15 wt%로 제한하였다. 결과에 의하면, AP 15 wt% 추진제는 AP 0 wt% 추진제와 비교하여 비추력 성능이 약 3% 향상되었다. 또한, 동일한 연소온도를 유지함에도 불구하고, AP 첨가비율을 증가시키면 산화제 유입량, O/F비 변화량, 그리고 연소압력은 감소하며 반경반향 온도 분포가 좋아지는 등 다단 하이브리드 로켓의 성능향상에 긍정적인 효과가 나타났다. 그러나 오직 AP를 추진제에 첨가하는 것만으로 다단 하이브리드 로켓의 비추력 성능을 일반 화학로켓의 수준으로 향상시키는 것이 매우 어려운 일임을 고려할 때, 추가적으로 금속입자 첨가를 통해 비추력 성능을 향상시킬 계획이다.
