The purpose of this study is to offer basic data to adolescents' cosmetic culture by investigating and analysing the choices made by female students who have been becoming principle consumers of cosmetics these days. Firstly, social and cultural backgrounds and concepts of N generation, and then characteristics and influencing powers of female students were reviewed. And this study also included questionnaire surveys of 500 female students in middle and high schools located in Seoul. Data were processed using a SPSS$^+$ program and analyzed by using frequency, percentage and the $X^2$-test. The major findings run as follows: Female students have the effects of spreading their words quickly and abilities of making a decision what to buy. And they accept consuming behaviors itself as a part of cultural lives. Therefore, industries have acknowledged them as new principal consumers with a powerful influence in the market. They also play an important role in active consumer as emotional generation who has distinct personalities and prefer fashion trends, changes and innovations. They show conformities with their peer groups and they also want to identify themselves with characters or stars. The cosmetic behaviors of female students relating to demographic characteristics showed a significant relation to grades, majors, school groups and places of residence. Female students have a lot of interest and knowledge about cosmetics. And they use various cosmetic products. This study demonstrated the age for using make-up for the first time has been becoming younger more and more. Recently, female adolescents tend to use face powder, lip gloss, mascara and eye shadow. It is assumed that cosmetic purchases of female students can be considered as an impulsive aspects. However, before purchases, the proportion of students having any particular cosmetic brand in mind previously has been increasing. They take into consideration skin safety, the quality of product and color, when purchasing cosmetic products.

This study was carried out to prove the therapeutic effects of BNJB on the catract. The objects of this study were CXSD mice that spontaneously eye rupture occurred from three weeks after birth and eventually generate cataract within 12 weeks. We applied eyewash made from BNJB to eyes of CXSD mice twice in a day till all the eyes of the negative control showed up the symptoms of a cataract and recorded the increasing patterns of cataractous eyes. To explained the therapeutic effects of the BNJB, We carried out the ex vivo experiment which cultivating eyeballs were offered oxidative stress condition by $0.03{\%}$ $H_2O_2$ during three days. Total co-enzyme was extracted from the cultured eyeballs and used to measure activities of catalase, superoxide dismutase, glutathion S-transferase and content of GSH. The results were obtained as follows: 1. When we treated the catalin to CXSD mouse as a positive control, it represented the delaying effect for cataract generation for 2-3 days compare with negative control. But it seems that it doesn't appropriate as a therapeutic, or delaying agent. 2. In the experimental BNJB group, Cataract formation rate was dramatically reduced by BNJB. This rate was much lower than positive group and means our new formulation for the therapy of cataract has a good potential. 3. In the analysis of individual medicines of BNJB, Mok-Jeok-Cho, Hwang-Lyun and Ha-Go-Cho didn't have a major effect of BNJB. 4. The cataract formation rate was repressed by Bing-Pyun and Jin- Joo-Boon about $40{\%}$ and $50{\%}$, respectively. We can presume that the anti-cataract effect of BNJB was caused by these two medicines. 5. When we surveyed the anti-oxidant activities of BNJB, enzyme activities of GSH, SOD, and Catalase increased about $10{\%},\30{\%}$, and 2.5 folds, respectively.

Context-aware systems are reactive computing systems, aware of external context. Considering various sensors and actuators connected, application programming on top of such systems is known to be much more complex than in contentional ones. This paper suggests a formal framework for context-aware systems, by extracting their common properties. That makes a useful birds-eye view for the behaviors of a whole complex system, as a base for a convenient developing environment and systematic analysis. In this framework, reactive-ness is handled by event-condition-action rules and global state-transitions, which are essential in a lot of context-aware applications. In addition, behaviors of each elementary device are modelled with its own state-transitions, and tightly bound to the entire task.

Objective: The purpose of this study was determine the effect of Balance Trainer training with Transcutaneous Electrical Nerve Stimulation (TENS) on spasticity and balance in persons with chronic stroke. Design: Randomized controlled trial. Methods: A total of 30 subjects with hemiparetic stroke were recruited and randomly divided into the Balance Trainer training with TENS group (n=15) and Balance Trainer training with placebo TENS group (n=15). The Balance Trainer training with TENS group practiced additional Balance Trainer training with TENS for 30 minutes a day, 5 days per a week during 4 weeks and the Balance Trainer training with placebo TENS group practiced additional Balance Trainer training with placebo TENS for the same period. Spasticity and balance were assessed by ability (static balance, dynamic balance) and were measured before and after the 4-week programs. Results: The result of spasticity and dynamic balance were improved significantly in both groups (p<0.05). The Balance Trainer training with TENS group showed significantly greater improvement in spasticity of the gastrocnemius & dynamic balance, compared to the Balance Trainer training with placebo TENS group (p<0.05). The Balance trainer training with TENS group showed a significant improvement in static balance, especially during the eye-closed condition (p<0.05). Conclusions: The Balance Trainer training with TENS was effective in improving spasticity and balance in subjects with chronic stroke. Based on these results, it is suggested that Balance Trainer training with TENS could clinically be used more actively in conjunction with conventional physical therapy.

The collisions at sea among marine casualties are not reduced as the tonnage and speed of ship's increase as well as the traffic quantity increase at sea, in spite of the improvement of nautical equipment, enforcement of crew's education and training as well as improvement of quality standard according to the implementation of ISM code. The measures to prevent the collisions at sea are simple, and are composed of six stage.: The first stage is that the officer on duty detect the target from his eye or radar information. The second stage is determining the type and kind of target-ship. The third stage is target tracking; calculation of target speed, course, CPA and TCPA from radar information or visual check. The fourth stage is determination of vessel in danger after calculation of third stage. The fifth stage is the judgement of situation if own ship is stand-on or give way vessel according to the 1972 COLREG. The last stage is to carry out proper action according to 1972 COLREG, under the circumstances. But by the case, the situations are so different under the different external conditions; for example, natural/navigational conditions, crew's human factors, ship's particular, rule or regulation, management system on board, the condition of watch keeping. Therefore the reasons and casualties are so complicated. This study aims to investigate the collision casualty at sea which needs to clarity all these causal factors of afore-mentioned, and to analyze the causes of problems so as to utilize them to establish the measures of preventing marine accidents. This study, described the concepts of causal factors into three groups; environmental factor, and company/on board management system and navigator's act. Also described how to investigate and analyzes the casual factors. Even though it was described in this paper how to detect the causal factors and reasons of collisions, and how to analyze the inter-relation of each causal factors, it is necessary to do further study how to analyze between the liability of concerned parties and the casual factors involved.

In this paper, we propose a face recognition algorithm based on the differential image method-DCT This algorithm uses neural networks which is flexible for noise. Using the same condition (same luminous intensity and same distance from the fixed CCD camera to human face), we have captured two images. One doesn't contain human face. The other contains human face. Differential image method is used to separate the second image into face region and background region. After that, we have extracted square area from the face region, which is based on the edge distribution. This square region is used as the characteristics region of human face. It contains the eye bows, the eyes, the nose, and the mouth. After executing DCT for this square region, we have extracted the feature vectors. The feature vectors were normalized and used as the input vectors of the neural network. Simulation results show 100% recognition rate when face images were learned and 92.25% recognition rate when face images weren't learned for 30 persons.

The purposes of this study are to develop the concept and the measurement method of IGS(Index of Greenness in Streetscape) and to analyze the present condition of street environments through field surveys of IGS in Seoul. IGS is a new index which directly expresses human's perceptions of plants in a street and defined as the area ratio of which leaves of plants occupy in an eye-level view of a person standing on the center line of a street. In practice, IGS can be calculated from a photograph taken from a center point of a street at about 1.5 meter height from the ground with single lens reflex camera equiped with 50mm standard lens. The photograph must have a special composition in a way that the center point of the photograph is positioning at the visual vanishing point of street center line. Then the IGS can be calculated by computing the percentage of the area covered with the plant leaves in the photograph. Types of streets in Seoul were classified according to road functions into 4 types. We performed field surveys and calculated IGSs from 300 sample sites in Seoul. Followings summarize some of study results. The average IGSs for arterial roads, highways, alleys and back streets are 16.91%, 16.33%, 13.97% and 7.50% respectively. The difference of average IGS values between Ginkgo biloba and Platanus occidentalis was relatively large. From observation IGSs from April 4th, 2003 to October 2nd, 2003, it was evident that the range and timing of each plant species' IGS change is not the same. According to questionnaire to public officials taking charge of street greening, the current evaluated IGS is 24.4%, and it is expected to be 40.7% in the future.

To compare animal production and grazing behavior, Wye college rotational, set stocking, modified set stocking and zero grazing system were set in Alpine area. Each system has one hectar and 4 head of Korean native cow. In order to investigate grazing behavior, eye observation was made every 2.5 minute for 15 hours of daylight from 5 a.m. to 20p.m. Results obtained were as follows. 1. The system of Wye college and rotational grazing have greater output of live weight per hectar than that of other gazing system applied. But practically rotational and modified set stocking were thought to be convenient grazing system for hill pasture and also modified set stocking was simple to operate, so that it seemed to be recommended as an alternative to rotational grazing system. 2. The daily live weight gain was the highest in May, the lowest in July and after then steadily increased. 3. Grazing hour during daylight varied from 331.1 min to 576.0 min by grazing system, but by season, herbage availability, weather condition. 4. Korea native cow tended to have three primary grazing time begining at one hour after sunrise, noon, and around 15p.m.

This study was conducted to investigate the toxicity symptoms and approximate lethal dose (ALD) of Oplopanax elatus (Nakai) Nakai hydrothermal extract powder by single oral dose toxicity and 4 weeks of repeated oral dose determination. The Sprague-Dawley (SD) male and female rats were treated with 1,250 (low- dosage group), 2,500 (medium- dosage group) and 5,000 (high- dosage group) mg/kg. In the single oral dose toxicity test, no dead animals and toxic symptoms were observed during the experiment. And there were no related with anomalies in normal weight changes and autopsy results. In the four-week repeated oral dose determination test, no death animals and toxicity symptoms were observed during the experiment, and there were no abnormal results in weight changes, feed and negative intake measurements. Results of eye examination, urinalysis, hematological values and serum biochemical values, gross findings and absolute organ were not of singularity. These result demonstrated that no toxic symptoms were observed by the test substance Oplopanax elatus (Nakai) Nakai hydrothermal extract powder under this test condition, and the non-toxic content is determined to be 5,000 mg/kg/day.
