The purpose of this study is to develop an inventory to classify task commitment types of science learning and to classify highschool students' task commitment types. Firstly, inventory questions were designed following the literature analysis on the task commitment components which involve self confidence, high goal setting, and focused attention. Prototype inventory underwent the content validity test, pilot test, and reliability test. Through these steps, final inventory was input to 462 high school students and underwent the factor analysis and cluster analysis. Factor analysis confirmed three components of task commitment as the three factors of inventory questions. In order to find how many clusters exist, factors of developed inventory became new variables. Each factor's factor mean was calculated and served as the new variable of the cluster analysis. Cluster analysis extracted five clusters as task commitment types. The 5 clusters were suggested by the agglomarative schedule and dendrogram gained from a hierarchical cluster analysis with the setting of the Ward algorithm and Squared Euclidean distance. Based on the factor mean score, traits of each cluster could be drawn out. Inventory developed by this study is expected to be used to identify student commitment types and assess the effectiveness of task commitment enhancement programs.

Purpose: This study was done in order to identify the effectiveness of open laboratory self-directed practice on knowledge, self-confidence, skill competency, and satisfaction of intravenous infusion in nursing students. Methods: This is a quasi-experimental study using a non-equivalent control pre-posttest design. The participants were 32 students comprising an experimental group and 30 students comprising a control group. The experimental group was allowed to perform open laboratory self-directed practice only. Pretest and posttest was performed through questionnaires of knowledge and self-confidence, and competence and satisfaction were assessed using checklists at posttest. Results: The score of Knowledge in the posttest showed no significant difference between both groups (F=1.28, p=.290), and those of self-confidence (F=3.87, p=.014) and competency (F=9.55, p<.001) of the experimental group were significantly higher than those of the control group. Conclusion: Open laboratory self-directed practice was effective in improving nursing students' self-confidence and competency of intravenous infusion. Therefore, students should be encouraged to actively participate in open laboratory self-directed practice and the effective strategies should be developed.

The Dynamic Gait Index (DGI) was developed and widely used as a clinical tool to assess balance performance during gait. The purpose of this study was to validate the Korean translated DGI using Rasch analysis. A total of 105 community-dwelling elderly was participated in this study (age range = 65~95 years; mean = 78.0 years). The translated DGI showed sound item psychometric properties, and the 8 items were arranged in order of difficulty for the total participants. The most difficult item was 'Steps' and the easiest item was 'Level surface'. Also, each of the original 4 rating scale categories satisfied the Linacre's essential criteria suggestions for optimal rating scale category effectiveness. Although, thirty eight person (36.2%) showed the maximal high score, but the most of them was no history of fall in the preceding year. For subjects who has falling history, all of the person's ability was arranged within the item's difficulty. The 8-item Korean translated DGI can be used to measure gain in elderly person with balance disorders without compromising important clinical measurement characteristics in Korea.

Psoriasis is a common inflammatory disease of the skin marked by excessive scaling associated with inflammation, affecting 1-2% of the population. Although their etiologies remain unknown, the finding of CD4+ and CD8+ lymphocytes at sites of psoriasis has led many reports to hypothesize that psoriasis is a T lymphocyte-mediated disease directed against unknown autoantigens. The oriental medicine understands the cause of psoriasis as low humidity of skin tissues and functional deteriorations of the liver and lung. Gami-Yunbueum (GY) is a mixture of two previous prescription, which were used to the protection of liver and lung. We had prescribed the GY to the three psoriasis patients for 11 weeks and examined the effectiveness of the GY by PASI (Psoriasis Area and Severity Index) score. In our experiment, GY improved the symptoms of psoriasis in all cases. These results indicated that GY can apply to the treatment of psoriasis. Furthermore, the process for treatment of psoriasis is possible to provide humidity to skin and control the functions of liver and lung.

Purpose: This study was conducted to investigate the effects of joint mobilization and kinesio taping on pain, range of motion and knee function in patients with knee osteoarthritis. Methods: Thirty subjects were selected and divided into three groups: group 1 was treated with joint mobilization, group 2 was treated with kinesio taping and group 3 was treated with joint mobilization and kinesio taping. Joint mobilization was performed for 20 minutes three times a week for a period of 4 weeks, after which tape was applied for the same period of time and it was not exceeded 24 hours. Pain, range of motion and knee function were then assessed to identify the effectiveness. A visual analog scale (VAS) was used for pain assessment, while active and passive range of motion (AROM, PROM) were assessed using smart phones application, and knee injury and osteoarthritis outcome score (KOOS) was used to assess knee function. Results: After intervention, the joint mobilization group and kinesio taping group showed significant improvements in VAS, AROM, PROM and KOOS (Symptom, Pain, ADL, QOL), whereas no significant difference was found in sport/recreation. The joint mobilization with kinesio taping group showed significant improvements in all items, and a significant increase was found in AROM and PROM compared to the other two groups. Conclusion: We found that joint mobilization and kinesio taping effectively improved pain, range of motion and knee function in patients with knee osteoarthritis, but that application of joint mobilization with kinesio taping was most effective.

In the past decade, considerable effort has been devoted unsuccessfully to the development of information technology (IT) evaluation frameworks in the information systems area. Based on the literature review in this area and the decision analysis field, two competing evaluation frameworks are developed in this study: the direct evaluation framework and the indirect evaluation framework. A case study on Firm K shows that the latter is more practically efficient and theoretically appropriate but requires the adequate training for practitioners in order not to get confused the weight of an evaluation variable with the product of this weight and the score of the variable. Another finding is that Weill's conversion effectiveness is neither possible nor necessary to measure in the process of evaluating an IT although it is in theory an important concept.

Background: This study was conducted to evaluate and compare the effectiveness of intravenous ketorolac and wound infiltration in producing postherniorrhaphy analgesia in pediatric surgery. Methods: Forty consenting healthy children, aged 3~7 yr, were randomly assigned to receive intravenous ketorolac (1 mg/kg) or wound infiltration (0.25% bupivacaine 0.3 ml/kg) before closure of the surgical wound after inguinal herniorrhaphy. Pain was evaluated by using an observer pain score at 30 min, 60 min and 4 hrs intervals, postoperatively. Results: It is statistically significant that the wound infiltration group had lesser pain than the ketorolac group at 30 min and 60 min. But there is no difference between the groups at 4 hrs, postoperatively. Conclusions: We concluded that wound infiltration may provide better analgesia compared to intravenous ketorolac for up to 4 hours postoperative for treatment of pain after inguinal herniorrhaphy in pediatric surgery.

In this study, an imaging mode of the modified SweepSAR is proposed with performance analysis for a high-resolution and wide swath coverage. To reduce the overall antenna size required for the solution of the azimuth ambiguity problem, different pulse repetition frequencies (PRFs) are utilized for different transmitters, respectively. For each imaging mode, system performance parameters are used for simulation, analysis, wide swath prediction, and comparison between conventional ScanSAR mode and SweepSAR mode based on scanon-receive (SCORE). The system parameters of AASR, RASR, and NESZ will be estimated and suggested on the imaging mode by using appropriate reflector antenna with the effectiveness of a modified SweepSAR employing dual channels.

The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.

Various characteristics of the object being lifted are known to affect the biomechanical, physiological, and psychophysical stresses. The object characteristics to be considered in the design process of lifting tasks are weight, shape, stiffness, and availability of handles and similar coupling devices. In this study, a prototype Polypropylene laminated bag with carrying handles was designed to decrease the physical stress of people who handle these bags. Physiological and psychophysical approaches as well as subjective ratings were applied to evaluate the effects of handles provided on the designed PP laminated bag. Statistical analysis showed that the VO2, heart rate, blood pressure, and Borg-RPE score for PP laminated fertilizer bag with carrying handles were significantly lower than those bags without handles. Moreover, Maximum Acceptable Lifting Endurance Time(MALET) measure, newly developed in this study, for bags with handles was significantly higher than those for bags without handles. It is thus recommended that the various types of bags and boxes be equipped with handles to reduce the musculoskeletal, physiological, psychophysical, and subjective perceived stresses.
