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.

This study estimated economic value and benefits of Yongsan National Park, which will be constructed by financial investment of the government and objectively estimated the real value of it by understanding the value of the park from a user's view of the park. For this, the value of Yongsan National Park is divided into using value such as carbon reduction and the function of relieving urban heat island as an environmental material and non-using value based on willingness to pay of the public according to the construction of the park. As a result of the analysis, it was found out that the using value of Yongsan National Park would reach 130 million won up to maximum level of 450 million won per year, and the non-using value was analyzed to be worthy of 2,344 won per capita every month. Besides, economic ripple effect that can be expected in the process of the park construction project was analyzed to be a national policy that creates effect on production inducement of 2.6 trillion won and value added of 809.6 billion won and new jobs for 25,620 persons. Considering the value of Yongsan National Park and the effect of the project based on the result of this study, it was found that it could sufficiently secure the validity of implementing the project compared to the financial investment by the government. Therefore, it must be emphasized that diffusion strategy is necessary for national understanding and for a nation to make it understood its appropriateness widely in respect to the construction of Yongsan National Park for the successful construction of Yongsan National Park and to raise its using value in the future.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

This paper is based on an experiment analysing the stress corrosion cracking behaviour of welding specimens compared to that of non-welding specimens of STS 304 HP stainless steel in corrosion solution. As a corrosion condition, stainless steel has been known to be the most fragile in a solution of 42% MgCl₂heated to the boiling point, therefore the experiment was carried out in this condition. The experiment was carried out with argon gas TIG welding specimens and non-welding ones made of stainless steel plates, thickness 2mm, by tensile force. At this time, the tensile force was taken to be the value of the yield strength of the tensile test specimens divided by the safety factor of 3.0 to 3.5, 4.0, 4.5, and 5.0. In this paper, the relations between Time of Initial Crack, Time of Failure, Time of Final Fracture and Crack Propagation Length were investigated and then plotted. Furthermore, the relations between Stress Intensity Factor K proposed by Irwin and the Time of Initial Crack, the Time of Failure, the Time of Final Fracture were calculated and plotted. At the last, all the relations plotted were expressed to normal equations by computer, and the equations were used to analyse the data obtained in the experiment. The conclusions obtained in this study are as follows: 1. Welding materials, compared with non-welding ones, as the Time of Initial Crack, the Time of Failure, and the Time of Final Fracture were generally very fast, appeared to be a phenomenon of unstable brittleness fracture. 2. Non-welding materials, compared with welding ones, as the safety factor was larger or the working stress was smaller, appeared to be a phenomenon that the longer had had greater durability. Therefor, welding materials must be considered enough to be used in heate affected and stress corrosion atmosphere. 3. The normal equations of the Time of Initial Crack and the variation rate to the same Stress Intensity Factor K are as follows: (A) Non-welding T =259702.4-5451.2 K+28.386 K² T = -5451.2+28.386 K (B) Welding T= -332.693+28.043 K-0.211 K² T' =28.043-0.211 K here, T; Time of Initial Crack, T'; Variation Rate of Time of Initial Crack to Stress Intensity Factor K, K ; Stress Intensity Factor.

This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

Because of the merit of nonoperative management of blunt hepatic trauma, which is the avoidance of operative morbidity, the use of nonoperative management has been extended. However the indications for such treatment have not been sufficiently determined. To suggest possible criteria for nonoperative management, we reviewed 95 cases with blunt hepatic injuries which were confirmed by abdominal exploration or abdominal CT in Gyeong Sang National University Hospital from January 1992 to October 2000. Of the 95 patients, 38 patients were treated with operation and 57 patients treated with nonoperative management. We analyzed the patients for age, sex, cause of injury, injured organ, injury grade, transfusion amount, and shock on admission, complications and mortality. The results are as follows; 1) The peak incidence of age was in the 3rd decade (20%), and the male-to-female ratio was 3:1. 2) The most frequent injury mechanism was traffic accidents (40, 42%). 3) The most frequently used diagnostic modality was abdominal CT (95 cases) in the nonoperative and the operative group. 4) On the liver injury scale of the American Association for the Surgery of Trauma (AAST), 13 were grade I, 18 were grade II, 10 were grade III, 13 were grade IV, and 3 were grade V in the nonoperative group ; 1 were grade I, 6 were grade II, 18 were grade III, 8 were grade IV, 4 were grade V, and 1 were grade VI in the operative group. 5) Between the nonoperative and the operative groups, there were significant differences in the systolic blood pressure in the first 8 and 24 hours, transfusion amount, and GOT/GPT level (p$lt;0.05). 6) In comparison of complication, there were 3 cases of heaptic abscess,1 case of intrahepatic hematoma, 1 case of bile leakage, 1 case of rebleeding in operative group (15.7%). There were 2 cases of intrahepatic abscess, 2 cases of intrahepatic hematoma, 4 cases of biloma, 1 case of subcapsular hematoma in nonoperative group (15.7%). In mortality cases, 6patients died in operative group. Among them, 5patiens died from DIC (disseminated intravascular coagulation) and multiorgan failure, 1patient died from ARDS (adult respiratory distress syndrome) in operative group and 2patients died from hypovolemic shock in nonoperative group. In conclusion, i) nonoperative management may be considered as a first choice in children and adults with blunt abdominal trauma and stable vital signs. ii) Patients with hemodynamically stable hepatic injury 8 hrs after resuscitation, even with an AAST OIS grade 4 injury, may be candidates for nonoperative management.

동기지향성에 따른 직무태도의 이원성

본 연구는 개인의 동기지향성 유형에 따라 자신의 직무에 대한 태도가 어떻게 달라지는가를 알아 보고자 하였다. 이를 위해 개인의 동기지향성 유형을 미동기화, 내재적 동기화, 외재적 동기화 그리고 이중동기화 집단으로 구분하였다. 이들에게 연구 1에서는 가설적인 직무상황을 제시하고 연구 2에서는 그들이 경험한 직무상황을 회상하게 하여 그 상황에서의 동기요인과 위생요인에 대한 태도를 측정하였다. 본 연구의 가설은 다음과 같다. 가설: 개인이 미동기화되어 있거나, 내재적으로 동기화되어 있거나, 또는 외재적으로 동기화되어 있으면 동기요인과 위생요인을 양극적으로 판단할 것이지만, 개인이 이중동기화되어 있으면 동기요인과 위생요인을 이원적으로 판단할 것이다. 위의 가설을 검증하기 위하여 두개의 연구를 계획하였다. 연구 1은 위생요인과 동기요인이 충실 또는 불충실한 4가지 가설적 직무생활을 피험자에게 제시하고, 각 상황에서 위생요인과 동기요인에 대한 태도를 측정하였다. 연구 2는 피험자들에게 실제 업무를 수행하는 과정에서 경험한 만족스러운 상황과 불만족스러운 상황을 회상하도록 하고, 그 상황에서의 동기요인과 위생요인에 대한 직무태도를 보고하도록 하였다. 연구 결과, 이중 동기회집단은 다른 집단들에 비해 위생요인과 동기요인을 더 이원적으로 판단하는 경향이 있었다. 끝으로 Herzberg 등(1959)의 2요인 이론이 개인의 동기지향성이라는 개인차에 의해 관찰될 수도 있고 관찰되지 않을 수도 있다고 논의하였다.

There are various Knowledge Representation techniques such as Production System, Semantic Network, Logic, Frame, etc. Among others, Semantic Network is more powerful, because it is more simple to retrieve the information relating to the object than any other techniques.Because it's representing structure is simple, it is fully described object and event using nodes and arcs.Thus, it is easy to represent an inheritance mothod and supply it to end-users. In this paper, we studied the roles of nodes and arcs in the Semantic Network and suggested the problems in representing logical connectives and quantifiers.
