We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

박승회,백광제,홍윤식 대한응급의학회 1993 대한응급의학회지 Vol.4 No.2

Chronic Obstrcitive Pulmonary Diseases(COPDs) produce significant morbvidity and mortality in human lives. COPD is a progressive disease that coexists with emphysema and chronic brochitis. The critical episodes depend on inciting or aggravating factors which can be classified into 3 ways. First, disease related aggravation. Second, Patient related aggravation. Third, Physician related(latrogenic). The authors reviewed 102 COPD patients who came to Korea University Hospital Emergency Medical center from March of 1992 to February of 1993. 1) Males were more frequently affected than females, and male to female ratio was 2.64 : 1 2) The average age of the patients were 62.8 years old. 3) The average number of hospital admission was 2.5 times and one patient was admitted 9 times for the same disease. 4) On an average, the patients had dyspneic symptoms for 15.6 years and the symptoms had developed since they were 47.8 years old. 5) The ratio between smokers and nonsmokers were3 2.1 : 1, the smokers had smoked for 36.3 years and the average amount of smoking was 1.5 pack per day. 6) After admission, sputum culture and sensitiveity test were done and the results were as follows : nonspceific organums 47 cases(46.0%), streptococcus 23 cases(22.5%), Pseudomonas 15 cases(14.7%), Hemophilus influenza 7 cases(6.8%), Klebsiella 5 cases(4.9%), Actinomycosis 3 cases (2.9%), Staphylococcus 2 cases(1.9%) 7) Aggravation factors for dyspnea were as follows : Upper Respiratory Tract Infection 40 cases(39.2%), Smoking 2.5 cases(24.5%), Pneumothorax 11 cases(10.8%), Pneumonia 7 cases(6.8%), Unknown origin 19 cases(18.6\%) 8) Prognosis after hospital admission were classified into 6 groups : 1. completely recovered 2. almost recovered 3. no improvement 4. hopeless discharge 5. expired within 48 hrs. 6. expired after 48hrs. The results were as follows : 87.3%(89 cases) discharged in almost recovered stated state, 1.9%(2 cases) discharged with no improvement, 4.9%(5 cases) were hoplessly discharged, 2.9%(3 cases) expired within 48 hrs, 2.9%(3 cases) expired after 48 hrs.

박제일,임승환 한국심리유형학회 2002 심리유형과 인간발달 Vol.9 No.-

본 연구는 대학교 학생생활연구소를 내방하여 상담을 받은 537명의 학생들을 대상으로, 학생들이 호소하는 문제유형과 성격유형과의 관계를 분석하여, 이를 토대로 내담자의 성격특성에 따른 적절한 상담대처방식을 적용하기 위한 기초연구로 진행되었다. 이를 위하여 내담자들이 호소하는 문제유형과 성적유형과의 관계를 분석하였다. 그 결과를 종합해보면, 내담자들이 호소라는 문제유형은 "학업 및 진로문제", "성격문제", "정서문제"의 순으로 나타났다. 성격유형 분포는 전체 분포에 비추어볼 때, "내향형"과 "직관형"의 비율이 높게 나타나고 있고, 성격유형과 내담자들이 호소하는 문제유형과의 관계에서는 ISTJ, ISTP, INFP, INTJ, INTP 유형에서 공통적으로 빈도가 높게 나타나고 있는 것을 알 수 있다. 따라서 이들 유형에게서 문제를 호소하는 비율이 증가하는 이유와 그 대책에 대한 논의가 필요하다. 또한 상담장면에서 성격유형별 대처방식에 대한 적용가능성에 대해 좀더 확대된 연구가 필요하다고 하겠다. This study was proceeded with 537 students who had counseling sessions in university students counseling center as the groundwork of applying appropriate counseling strategies according to the client's personality type, on the basis of the analyses of relations between the types of problems students complained about and their personality types. For this purpose, analyses were proceeded to figure out the relations between the reffered problem types and personality types of student clients in university. In summary, the problem types clients complained about appeared as "problems in schoolwork and career", "problems in personality", and "emotional problems" in order. Compared with the whole personality type distributions, "Interversion" and "iNtuition" types occupied higher rates than other types, concretely, ISTJ, ISTP, INFP, INTJ, and INTP types showed higher frequencies in common than others. So, it is necessary to discuss the reason why the problem complaining rates showed higher levels in these types and the strategies of the counselors to cope with these types of clients appropriately. And further study is needed to research the applicability of strategies of counselors according to the personality type of client's in counseling setting.

Unbraced Tubular 아치교에서 아치리브의 단면력과 거동에 관한 연구

박정웅,유제승 朝鮮大學校 建設技術硏究所 2003 建設技術硏究 Vol.23 No.1

Arch bridge has widely been applied because it presents the beauty of unique curves to a structure, distributes horizontality the reactions due to load effectively, and makes it possible to construct economical bridges with appropriate plans. Recently, tries to transform the old types of arch bridge have been done. Of all, the most representatives are unbraced arch bridge which applies circular section of tubular to arch rib to diminish a shape factor. Some foreign countries have these bridges. In Korea, there is no examples but it has just been proposed as the plan. For the many merits of unbraced tubular arch bridge the increase in the instances applying it to construction is expected and more research is demanded. Resultingly, in this study, when the arch rib is constructed with inclined angle perpendicular to the axis of bridge to present the beauty of unbraced tubular arch bridge, the strength under the inclined angle of arch rib is examined using the Finite Element Method.

This study was proceeded to develop a scale for self-concept which assesses the interpersonal relationships with social interactions in the center, affecting such great Influences on one's self-concept. In the process, a novel scale has been developed through integrating and extracting items related to interpersonal relationships from those scales for self-concept up to now. This study was executed two times. In the first period, among the whole subjects of 279, staff members of 'H' group, 'J' hospital, and 'S' group were included in, with 28 males and 247 females. When classified into age, they were constituted of 234 in twenties, 32 in thirties, and 8 in forties. In the second period, the subjects were 218 of undergraduate students in 'K' university and 450 of high school students in Busan. The whole 668 subjects were constituted of 233 males and 435 females. In the results, five items had been deleted in the first analysis and 3 items has been deleted to remain final twelve items. The final confirming scale for interpersonal self-concept is constituted of three factors, self-value, self-affirmation, and self-efficacy. The factor 'Self-Value' can be explained as the understanding himself and that he is contented with himself, 'Self-Affirmation' can be the factor that explains the tendency to recognize himself as positive, and the 'Self-Efficacy' as the tendency of acknowledging his own abilities of problem solving skills in the process of interactions with other persons. The limitation of this study is that to reconsider the possibilities of the use of this scale, such broad validation processes are remained.

박승희,우제창 木浦大學校 基礎科學硏究所 1995 基礎科學硏究誌 Vol.13 No.-

Using a binary vector system with pea rbcS gene and hygromycin phosphotransferase gene for selectable marker, tobacco plant was transformed by means of a leaf disc transformation method. After co-cultivation, bacterial cells were removed by cefotaxim treatment. Transformed shoots were developed from the co-cultivated leaf disc within 1 to 2 weeks in selection media supplemented with 25㎍/㎖ hygromycin and 50㎍/㎖ kanamycin. While normal plants could not grow in the medium with 25㎍/㎖ hygromycin the transformed plants could survive in the medium with 200㎍/㎖ hygromycin. It meant that resistant gene and rbcS gene was expressed in regenerated tobacco plants. Differential protein accumulation of RUBISCO small subunit was not detected by SDS-PAGE.

Seasonal and vertical distribution of water quality were investigated from May 2001 to June 2002 in Kumoh reservoir located nearby Kumi City, Kyungpook. Kumoh reservoir that lost the role of agricultural irrigation is currently of rapid eutrophication. The vertical distribution of DO was observed clinograde with hypolimnetic anoxic zone. T-P concentrations at the surface ranged from 0.008 to 0.152 mgP/L and T-N concentrations ranged from 1.4 to 3.0 mgN/L. The vertical and seasonal variation of T-N was smaller than T-P. DOC concentrations, indicator of organic matter pollution, ranged from 2.8 to 5.4 mgC/L. Apportionment of Total-DOC (T-DOC) indicated that 14% of T-DOC was attributed to Labile-DOC(L-DOC) and the rest was due to Refractory-DOC(R-DOC). The values of TSI(Trophic State Index) ranged between 44 and 52 indicating that Kumoh reservoir is under mesotrophic condition. The results of this study indicate that Kumoh reservoir is likely to be under influence of eutrophication and thus water quality will be aggravated. Therefore, the Kumoh reservoir requires further treatment to improve water quality and a plan of the reusing water resource should be developed.

오승민,연제덕,남혜운,박대규,조명행,정규혁 성균관대학교 약학연구소 1998 成均藥硏論文集 Vol.10 No.1

l-Muscone is synthesized for use as substitutive material of musk which is the active ingredient of woohwangchungsimwon. The objective of this investigation was to evaluate the acute and subacute toxicity of l-muscone in rats. In oral acute toxicity test, SPF Sprague-Dawley male and female rats were gavaged with l-muscone of two doses(0, 5.0g/㎏). No dead animal and abnormal autopsy findings were found in control and treated group. Body weights were slightly decreased in both sexes of rats treated with 5.0g/㎏. Therefore, oral LD_50 of l-muscone was consider to be higher than 5.0g/㎏ in male and female rats. In intraperitoneal acute toxicity test, rats were injected intraperitoneally with dosages of 0, 1,000, 1,316, 1,732, 2,279 and 3,000 ㎎/㎏. Decreased body weights and motor activities were observed at high dose group. Intraperitoneal LD_50 of l-muscone were 1,920 ㎎/㎏ in male and female rats. In the subacute study. l-muscone was administrated orally to both sexes of rats for 4 weeks as several doses(0, 10, 100 and 1,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data suggest that no observed adverse effect level of l-muscone in rats might be over 1,000 ㎎/㎏/day in this study.

Some authors suggest that certain types of surfaces are the origin of such injuries. A few years after the first medical concerns about surfaces were voiced, publications of biomechanical measurements apperared, describing accleration, force, and impact measurement on different types of surfaces. In many sport activities, surfaces can be under very high dynamic load. This was the reason for the development of various methods for impact simulation, like the development of various methods for impact simulation, like the artificial athlete. Furthermore, it is important to collect information about the hardness of new and already existing surfaces in sport arenas. The idea on which this measuring system is based Is as follows: The stiffness of the material can be computed from the kinematics measurd at touch down of a rigid body onto a material sample. The results show the following The result for the artifical surfaces(Synpave ace) is surprising. It is known that these surfaces are much harder than synpave rebound classic, synpave spring. This finding suggests that it may be possible that the subjective impression is used as one criterion in the selection of landing(or style) strategies. The number of subjects in this experiment is too small to make statistically significant conclusions. It is shown analytically that when an object a deformable surface, the acceleration it experiences is inversely propotional to its mass. In future, it need to stress that the interaction between shoe and surface is important, and this aspect has now become well accepted. Considering biomechanical aspect in player's injury, it request Korean Standards for synthetic playing surfaces in sport like ASTM(America Society for Testing & Materials) standards of America, DIN 18035 standards of Germany, BSI standards of U.K.

The acute and subacute toxicity of New Woohwangchungsimwon(NWCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats(Sprague-Dawley, SPF) were injected intraperitoneally with dosages of 0, 540, 750, 1,070, 1,500 and 3,000 ㎎/㎏. Body weights were significantly decreased at 540 ㎎/㎏ dose group in both sexes and abnormal autopsy findings were founded in both sexes at all treated groups. Intraperitoneal LD_50 of NWCH was 812.3 ㎎/㎏ in male and 872.3 ㎎/㎏ in female rats. In the subacute toxicity study, NWCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800 and 2,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NWCH might be over 2,000 ㎎/㎏/day in this study.
