Purpose : Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. Methods : Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. Results : In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. Conclusion : Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.

To overcome the drawbacks of existing classes, this study developed a liberal arts education class model based on online-collaborative learning under the cloud based class environment. That will be the comprehensive model for classics reading, discussion education and foreign language education. This study started from the need of developing the college classes for embodying the collective intelligence. This course must be effective to maximize the educational effects and mutually interdisciplinary progress. Therefore, the offer of the applicable model will be able to establish collective intelligence and extend the educational effects. This study presented the proposed comprehensive model effects as follows: 1) this comprehensive model could create the learning environment so that individual intelligence may be converged into collective intelligence. 2) regarding their intellectual inquiry and the contents of thought, this model could activate the learners' participation in the discussion by mutually exchanging the feedbacks between teacher-learner and learner-learner. 3) cloud based online-collaborative learning environment could reduce learners' affective burden and overcome the drawback of offering the offline limited data. Thus, given these results, this model can be expected to allow us to draw the positive results in overall education fields along with liberal arts education, discussion education and foreign language education.

Bronchogenic cysts are anomalous cystic lesions of foregut and usually located in the lung or mediastinum. Generally intramuscular cysts of the esophagus are considered as enterogenous foregut malformations. We report a young adult with an intramural bronchogenic cyst causing dysphagia and heartburn. It was located in the muscular layer of the esophagus and was removed without any damage to the mucosa. Histopathologic findings revealed that it was a bronchogenic cyst.

Collective intelligence is related to several areas such as sociology, business administration, political science, and computer science. This paper can be classified as a product of social engineering of the era of liberal arts and science convergence, fusion, consilience. Members today have higher need for self-actualization and contribution. As the business is changing fast and getting more complicated, a mechanism of natural science is necessary in social organization. The mechanisms of collective intelligence are composed of divergence process and convergence process. And the seven steps were designed that the first letter of each steps leads to 'PROCESS'. When implemented by applying the procedures that reflect the opinions of members throughout this paper, there are members who participated in the decision-making process will contribute to actively participate in the decision when to run, and specific tools and techniques in online communities are for future studies.

Semantic search recently been used in the search field. POI is one of the most essential information that make up the geographic information, and many of the geographic information system has POI search function as a basic. In this study, we propose POI semantic search using collective intelligence. For this, we designed and implemented service that constructs empirical information from tag and image, and provides an intuitive spatial navigation experience. For POI search, collective intelligence platform that many users can participate to collect variety information was designed and implemented.

Digital Terrain Model is composed of two basic elements, namely, sampling and interpolation. They represent the procurement of data and the geometric reconstruction of terrain relief respectively. For evaluation DTM data, following two paremeters appear to be the most important factor, that is, the accuracy and efficiency and, in particular, the break point information significantly affect to the accuracy of DTM data. The main objective of this study is to improve the accuracy and efficiency of DTM by applying Progressive Sampling with distinct morphologic information. In this study, the total of 240 individual numerical tests has been implemented and the appropriate computer program is also developed for the test. The result of investigation shows that the Progressive Sampling with break point information improves the accuracy of DTM by 30 percent approximately.

Bronchogenic cyst is an uncommon congenital lesion which is derived from the primitive foregut. Most bronchogenic cyst may develope at the tracheal bifurcation, both main bronchi, the lung parenchymeand the mediastinum. A 40-year old male was evaluated for dyspnea and chest tightness. Computed tomography revealed a well dermarcated, 7.2 ${\times}$ 7.9 cm sized, homogeneous mass compressing the left atrium. 2D-echo showed grade III mitral regurgitation. We completely removed the cystic mass and then confirmed the bronchogenic cyst in the pathological diagnosis. During the follow up period, the patient progressed well without any symptoms and showed grade I mitral regurgitation on the 2D-Echo. Therefore, we report a case of the bronchogenic cyst causing grade III mitral regurgitation.

This study investigated the relationship between the physical features and personality impression of faces. Subjects were exposed to male and female facial photographic images. Using 7-points scales, subjects were asked to rate 31 personality traits. The three factors extracted from factor analysis were labeled social desirability, activity, and intelligence. The analysis of correlation between physical features and factor scores of faces indicated that there is a significant correlation between features of eye of male faces and intelligence and between features of chin of female faces and intelligence and social desirability. These results suggested that subjects judged the personality impression, based on different physical features in male and female feces.

Starting from common sense that happiness is a state where needs are satisfied, this paper suggests the intelligence and the virtues for democratic citizens. The fact that human beings exist, relate to each other, and undertake activities which can become of moral worth when joined by autonomy, equality, and responsibility, respectively, is explained. It is also discussed that happy citizens should be able to exist autonomously in the face of political power, make an equal relationship with political power and fellow citizens, and undertake responsible activities. Lastly, it is suggested that happy citizens should be able to understand the plurality of value-contents, the similarity of value-forms, and the possibility of value-realization, and then be equipped with self-respect, mutual respect, and law-respect.

Recently performing arts pursue a new rootage of the collective intelligence that seeks experimental thinking and diversity in creative convergence. Understanding in this way the concept of artist's horizontal creation structure and individual communication of the public, this study tries to analyze ${\ll}God's\;Eye\;View{\gg}$, an example of convergent performing art. The result of analysis is as follows. The convergence in performing art could be approached through experiential thinking and diachronic of artists by genre, and the interpretation and its value of the result of work be shared horizontally. ${\ll}God's\;Eye\;View{\gg}$ express a dynamic communication and meaning of poetic image, and shows the experimental creation of convergence and the individual communication ability of collective intelligence as a new value of convergence.
