  • Ostomates have suffered from many difficulties due to their physical, psychosocial handicaps and changes of life style to include ostoma management that influences their daily and quality of life. An appropriate nursing education for ostoma management is very important. Practical educational materials needs revision because those were developed by pharmaceutical companies and hospital institutions. The purpose of this study is to provide more practical and reasonable education materials for ostomates by doing analysis and survey of educational materials now being used. We surveyed 8 types of educational materials used in 23 university hospitals and medical centers in Seoul ; four of them were developed by department of nursing and the remainder by an Ostomy Company Data, collected from July 14, 1997 through July 31, 1997 were analyzed. The results are as follows ; 1. The analysis of education guide, on ostomate included 14 subcategories : introduction, structure and function of gastrointestinal tracts, definition of stoma, types of ostomy, definition of peristalsis, methods of defecation management, selection of instrument, resolution of problems and general situations following surgery, daily life, where to ask for help, explanations for terms, information about where to buy instrument, explanations for enterostomal therapist, a matter of consultation with doctor, etc. 2. Introduction contained specific contents on practical ostomate management that ostomates would experience through their lives. Ostomate education guides were developed 3 hospitals except one which missed this point. 3. Most ostomate education guides, except one hospital, helped ostomates to understand their physical structure changes with specific explanations on gastrointestinal tracts with figures. 4. Six institutions did not talk about the definition of peristalsis. 5. All institutions, except two, helped ostomates to understand types of ostomy with figures. 6. More detailed explanations on natural defecation are needed. The benefits and pitfalls of natural defecation should be more specified. 7 No psychosocial difficulties of ostomy management were addressed. 8. The efficiency of enema can be better understood through all explanations with figures. Some institutions did not mention items about definition, benefits, pitfalls of enema, sequency of enema, how to wash, cautions performing and enema, skin management, cleaning instrument after enema proper time to spend. 9. There were no detailed contents and what to do in case of not being able to do enema. 10. Only one educational material mentioned emotional aspects after the surgrey. 11. Most institutions explained subcategory of daily life but did not provide specific contents on the difficulties of physical, psychological, and sociocultural controls. 12. The subcategory of ureterostomy education guides included explanations on normal structure and function of urinary tracts, types of ureterostomy, how to manage skin, usage and types of instrument, commercial urostomy, how to manage instrument, daily life, introduced the general contents. However, more specific explanations were needed.

  • Purpose: To evaluate the efficiency of arthroscopic treatment for infected total knee arthroplasty (TKA), and to investigate the factors affecting the outcomes. Materials and Methods: We analyzed 17 cases which underwent arthroscopic treatment to treat infection after TKA. After confirming infection by hematologic examination and analysis of joint fluid, we performed arthroscopic debridement, synovectomy and irrigation with normal saline mixed with antibiotics. Through routine examination after operation, we checked failure of treatment or recurrence of infection. If there is no recurrence until 2 years after the operation, we considered it as a success of treatment. Results: Of the 17 cases taken arthroscopic treatment, 13 cases were treated successfully with primary arthroscopic treatment only, but 4 cases had to undergo re-operation because of persistence or recurrence of infection. Analyzing the factors affecting the results, we found that symptom duration of the re-operation group is longer than the treated group after arthroscopy (p<0.05). Conclusion: Arthroscopic treatment can be effective when we performed appropriate selection of patients, careful and extensive arthroscopic irrigation and debridement, and suitable use of antibiotics. However, we have to do early arthroscopic surgery as soon as possible when infection after TKA is suspected.

  • If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.

  • This study aims to provide basic data about the diversification and the development of sauces by making four kinds of Teriyaki sauce, and the findings are as follows. The satisfaction with Teriyaki sauce by age and cooking career and groups showed a significant difference in several items. According to the result of the preference analysis on professors and teachers, the preference for health/nutrition showed a significant difference; also, the result of the preference analysis on Teriyaki sauce ingredients among the culinary students showed a significant difference in awareness and health/nutrition. In addition, the result of the preference analysis on Teriyaki sauce ingredients among college students showed a significant difference in the order of taste, awareness, price, and health/nutrition. Lastly, the result of the preference analysis on Teriyaki sauce ingredients among all groups showed a significant difference in the order of awareness, price and health/nutrition. As the mindset that main ingredient of Teriyaki sauce is eel bone prevails and the sauce made by crab shells is highly preferred, sauces added with sea food products are considered to be possibly developed. The follow-up study will have to deal with a manufacturing method of sauce with high nutrition and economy efficiency resulting from cheap manufacturing unit price by making Teriyaki sauce with inedible but nutritions sea food products.

  • In the era of the 4th Industrial Revolution customers living began to come out, not inside the purchase funnel. Due to the diversity of product selection and the increase in digital channels, the way customers search for information and purchase it is changing innovatively. So, the customer journey in the digital age is much more complicated than the traditional funnel model suggests. Unlike many previous studies, this study was conducted for 1,200 customers in four product groups of fashion, automobile, cosmetics, and online shopping malls. As a result of the study, we investigated how digital self-efficacy plays a role in purchasing in a series of processes in which digital experience affects customer satisfaction and finally affects purchase. As a theoretical implication, as a result of introducing and testing digital self efficacy as moderated mediation effect. the digital self-efficacy between customer satisfaction and customer loyalty were determined to play a moderated mediation effect role. As a practical implication, it was necessary to actively utilize digital marketing for customers with high digital self-efficacy, but it was suggested that customers with low digital self-efficacy need to be careful about digital marketing fatigue.

  • A land cover map provides basic information to help understand the current state of a region, but its utilization in the ecological research field has deteriorated due to limited temporal and spatial resolutions. The purpose of this study was to investigate the possibility of using a land cover map with data based on high resolution images acquired by UAV. Using the UAV, 10.5 cm orthoimages were obtained from the $2.5km^2$ study area, and land cover maps were obtained from object-based and pixel-based classification for comparison and analysis. From accuracy verification, classification accuracy was shown to be high, with a Kappa of 0.77 for the pixel-based classification and a Kappa of 0.82 for the object-based classification. The overall area ratios were similar, and good classification results were found in grasslands and wetlands. The optimal image segmentation weights for object-based classification were Scale=150, Shape=0.5, Compactness=0.5, and Color=1. Scale was the most influential factor in the weight selection process. Compared with the pixel-based classification, the object-based classification provides results that are easy to read because there is a clear boundary between objects. Compared with the land cover map from the Ministry of Environment (subdivision), it was effective for natural areas (forests, grasslands, wetlands, etc.) but not developed areas (roads, buildings, etc.). The application of an object-based classification method for land cover using UAV images can contribute to the field of ecological research with its advantages of rapidly updated data, good accuracy, and economical efficiency.

  • The input-oriented project promotion system private participation in infrastructure projects currently in use in Korea has encountered difficulties in securing the primary benefits of private sector creativity problem solving and inflow of private capital. As such, the performance (or output)-oriented procurement process implemented in England and other developed countries should be evaluated for introduction. In Korea, private participation projects are currently identified as either solicited or unsolicited projects, each with different promotional procedures, the problem with these procedures is that competition is not pre-activated, the private sectors creativity is under utilized, and the rationality of project evaluations is inconsistent. Korea should, in order to raise the level of private sector creativity and efficiency, go beyond the currently applied Input Specification project promotion system to a Performance-oriented system similar to those implemented in England and other countries. To achieve this, we mate several proposals for the introduction of the performance-oriented system. We divide the main features of our proposals into three categories, including a reformed concessionaire selection system, a performance orientation in preparation of the concession agreement, and a performance orientation in contract management, and discuss each. 1'his study describes performance-oriented promotion systems in an output-focused way As this is an initial study on the introduction of performance orientation in private participation, various key points and proposals were identified. However, in the future, detailed research in technical fields and systems, legal research, and practical projects will be needed for implementation

  • This study analyzes the process of establishing BSC based strategic performance evaluation system of KOMSCO. This case could be a reference to other public institutes for BSC introduction and efficient BSC usage. Internal control system of KOMSCO has been improved by EVA system in 1999, BSC introduction and Job analysis in 2001 through 2002, and BSC performance evaluation system in 2004. KOMSCO tries to reflect BSC concept by inducing employees to cooperate selection process of CSF and KPI and by considering the organizational characteristics of KOMSCO in constructing it's performance indices. It is suggested that these processes are very important and should be followed by other institutes in their BSC introduction. By applying BSC, KOMSCO provides improvement in employees' understanding of strategy, performance management, and performance evaluation. KOMSCO' information system based on ERP and efficiently connected to EIS, KMS, and BSC seems to play an important role of BSC application. BSC system of KOMSCO is now in the early stage of application and needs to be evaluated by the efficiency of usage in terms of overall performance evaluation system, deduction system of evaluation point for excess accomplishment over target, and connection to budget system.

  • In order to investigate the effect of floor condition on the fattening performance of cattle, sixteen finishing Hanwoo steers of weighting 570kg were fed for 16 weeks to slaughter on two types of sawdust bedding pen oriented to the south(SP) and the north(NP) then obtained following results. The floor condition of SP roofed by transparent material was dry and flat during overall experimental period, whereas, that of NP roofed by solid slate was muddy and rough even in summer and fall, and then frozen in winter period resulted in interfering with the locomotion and resting behavior of steers. Average daily dry matter intake of steers was not different between tow treatments, however, the average daily gain of steers in NP and SP was 0.64kg and 0.75kg, respectively, meaning that gained 14.3% less for the NP group(p<0.05), accordingly, feed requirement(feed/gain) and TDN/gain increased by 15.9% and 15.5%, respectively. No significant differences were found in slaughter weight, carcass weight, dressing percentage, meat yield index and meat quality traits between two treatments. In conclusion, this study revealed that poor floor condition of feeding pen could decrease weight gain and feed efficiency of cattle by increasing energy consumption for locomotion and conductive energy loss while resting on the floor surface. These results indicates that housing orientation of cattle shed and the selection of roof material are important factors in beef cattle production.

  • In this report, several factors such as infection time and concentration of bacterial suspension, influencing on transient gene expression in Agrobacterium-mediated transformation were evaluated. An appropriate concentration (O.D 600nm = 1.0-1.2) of bateria and 30 min of infection time showed a higher level of GUS expression. To improve transformation efficiency (TE), friable embryogenic calli (FEC) were bombarded by tungsten particles without plasmid DNA, and then co-cultivated with A. tumefaciens LBA4404 which contains pTOK233 super binary vector, carrying neomycin phosphotransferase (NPTII), hygromycin phosphotransferase (hpt) and$\beta-glucuronidase$ (GUS) genes. Three days after co-cultivation with A. tumefaciens and particle bombardment, FEC cultures were transferred to the selection medium (SM: MS medium supplemented with BA 1mg/l, hygromycin 100mg/l, cefotaxime 250 mg/l and vancomycin 200mg/l). They were cultured for 2 weeks and then transferred to the second SM containing hygromycin 50mg/l, cefotaxime 200 mg/l and vancomycin 100mg/l. Later, stable GUS expression was detected 4 to 6 weeks after transfer to the SM. Further, TE from Agrobacterium-mediated transformation after particle bombardment increased to about 3-folds compared with Agrobacterium-mediated transformation without particle bombardment. In the present study, we established an efficient transformation protocol of zoysiagrass by using A. tumefaciens in the combination with particle bombardment for the first time.
