Intellectual output, such as research papers and patents, has increased due to the consistent investment of the government R&D budget, however, the economical outcome leaves much to be desired. These unsatisfactory results originate from the lack of information sharing about the technology's business compatibility and enterprise's business capability between technology supplier and technology user. This study aims at investigating the decision making process of technology commercialization by proposing an assessment model of the technology's business compatibility and enterprise's business capability. The assessment model was completed by selecting the key index through a literature survey, field survey and consultation with experts. The technology assessment model can be effectively utilized for technology licensing, technology start-up and technology selection in R&BD projects. However, the assessment indexes required for the basic science are not investigated in this study and some assessment indexes are differently interpreted by the individual appraisers. The assessment model will be improved through field application and additional studies will be conducted to develop the assessment model of basic science.

This research extracted emotional words for measuring user's emotions expressed while using a cellular phone and a web. And then the emotional words were compared to find out whether the difference in emotional words by the type of products. The results of this study suggest that the hardware-oriented products used for specific purpose such as cellular phone extracted a lot of emotional words related to 'Satisfaction in Usability' and 'Pleasure'. 'Satisfaction in Usability' are conceived satisfying in usability or practicality of product. 'Pleasure' are pleasant emotions expressed while using a product. However the emotional words related to 'Aesthetics' and 'Novelty' were omitted. 'Aesthetics' are expressed by product's appearance and by various visual information while using a product. 'Novelty' are expressed by something that is novel and new that has never been experienced. On the other hand the software-oriented products used rather to find something better and new information than to perform specific tasks such as web extracted a lot of emotional words related to 'Novelty'. Therefore, the results of this research have found evidence that it is desirable to make a set of subjective evaluation scale by the type of products. When making the subjective evaluation scale, it is important to use appropriate emotional words for the purpose of use and the characteristics of those products.

The purpose of this study was to identify the influence of diet related factors, such as diet behaviors, food intake, and nutrient intakes, on self-rated health (SRH). Also, in order to determine fitness of classification for SRH reflecting diet related factors, this study surveyed older adults in Gyeongnam province. A total of 101 responses were collected using the interview survey method. The self- rated health of rural older adults was poor as reported by 49.5%. The level of self-rated health was found to be related to the frequencies of coffee and snack, use of sugar and vegetable in diet, the amount of total food intake, and cholesterol intake. The result of discriminant analysis, which was conducted to assess the adequacy of SRH classification and to determine the class of observation, showed frequency of coffee and use of vegetable in diet among 47 variables as predictive variables for explaining SRH. The fitness of self-rated health function was high to 47.7%. Therefore, diet-related factors were ascertained to be important variables to predict SRH.

Purpose: This study examined clinical cure and patients' satisfaction degrees by factors influencing surgical operation results, after arthroscopic inside to out repair as a nonabsorbable suture material, in case of meniscal rupture. Materials and Methods: Materials were 110 cases of 95 patients who could make paces for over 12 months from August 1999 to June 2002. Results were evaluated by clinical cure and subjective satisfaction degrees. This study, concerning those results, analyzed age, term from taking pictures to taking surgical operation, rupture section, rupture length, rupture types, lesion of articular-cartilage, and effects of anterior cruciate ligament operation accompanied. Results: 84 cases(76%) were clinically cured, 98 cases(89%) were subjectively satisfied. In case of accompanying anterior cruciate ligament rupture, and in case that rupture length was below 2 cm, rates of clinical cure and patients subjective satisfaction were significantly high. In case of complex or degenerative rupture, patients satisfaction rates were higher when comparing with clinical cure rates. Conclusion: Various sutures are possible as well as available in case of arthroscopic meniscal inside to out repair using nonabsorbable suture material. It can be concluded that patients age is not absolte consideration in determining the suture of meniscus. In cases of complex rupture, degenerative rupture, ruptures companied by joint-cartilage injuries, considerate consideratin need be paid to choose patients and operations.

Objectives : The purpose of this study was to examine cognitive and psychological characteristics of patients who visited psychiatric outpatient clinic with military service suitability issues. Methods : Since January, 2017 to September, 2018, patients were recruited from the department of psychiatry of university hospital. Participants were diagnosed using DSM-5 criteria by board certified psychiatrists. And each of participants tested with K-WAIS-IV, K-SCL-95 by clinical psychologist. The data were analyzed using SPSS 18.0. Results : The results indicated 24.6% of the patients have significantly low level of intellectual functioning. and 10.8% of the patients have borderline level of intellectual functioning, and 26.3% of them were below average. The results of psychological characteristics showed patients have cautious and potentially dangerous level of depression, anxiety, agoraphobia, and suicidal idea. And PTSD subscale's mean score was above problematic level. Next, we divided patients into two groups based on question of whether the patient is eligible to serve in the military service or not arises from recruitment process or army training center. But two group didn't differ significantly. And for further analyses, we also divided patients into two groups based on if they got single psychiatric diagnosis or more than one psychiatric diagnosis. Conclusions : The results indicated that group which has coexisting psychiatric disorders were more depressed, had higher level of anger and aggression, and had more serious levels of suicidal ideas than single psychiatric diagnosis group. The implications and limitations were discussed along with some suggestions for the future studies.

In this study, we assessed the performance of the test remote pointing device that is applicable to interactive TV (iTV). An empirical test was carried out with the pointing devices in three different interface methods that are recently tried in the industry. For the measurement, a directional task was performed on the linear track described in the conventional ISO 9241-Part 9. The measured variables included the movement time, accuracy, throughput and the subjective satisfaction. The result showed that the motion time was better in the device in the GyroPoint method than the other devices, but the accuracy of the GyroPoint device was lower than that of the devices in the Hall Mouse and OFN methods. It was found that the throughput and the subjective satisfaction were dependent upon the individual input devices. Since this study was conducted on the major point devices that are currently tried and analyzed the problems and characteristics, it is assumed that this study will provide useful data for the design of the remote pointing device that is more suitable to the iTV environment.
