Purpose: To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. Methods: A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, $x^2$ test, and t-test. Results: After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, p<.001), regular exercise (Z=-4.47, p<.001), and quality of life-MCS (t=3.04, p=.004) and showed lower levels of stress (Z=-3.53, p<.001) and sodium intake (t=-4.43, p<.001) than those in the control group. There were no significant group differences in medication adherence and food intake in total energy, lipids, and cholesterol. Conclusion: The suggested SP-PCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI.

Objective : This study was performed to evaluate the toxicity after a single oral administration of black raspberry extract to male and female Sprague-Dawley (SD) rats and to determine the approximate lethal dose (ALD). Methods : We previously showed that the black raspberry extract repressed the simvastatin-mediated expression of Proprotein convertase subtilisin/kexin type 9 (PCSK9) and improved Low-Density Lipoprotein cholesterol (LDL-C) uptake by hepatocytes through the induction of the Low-Density Lipoprotein Receptor expression in hepatocytes. The groups consisted of black raspberry extract groups, as an oral dose of 2,000 mg/kg and a control group. 5 weeks SD rats were randomly assigned to 4 groups of 5 rats. Each male and female SD rats were administered orally once. For 14 days after the administration, mortality, clinical signs, changes in body weight, and necropsy findings were observed according to the "Standard for Toxicity Study of Pharmaceuticals" of Korea Food and Drug Administration (KFDA) guideline and "Acute Oral Toxicity- Fixed Dose Procedure" of OECD Test Guideline. Results : There were no cases of mortality in the group administered with 2,000 mg/kg of male and female, and no abnormalities in body weight change and clinical signs. Also, no gross abnormalities were observed at the autopsy. Conclusions : As a result of a single oral administration of the black raspberry extract to SD rats, the ALD was determined to exceed 2,000 mg/kg for both male and female SD rats.

The purpose of this study was to evaluate the current state of foodservice and clinical nutrition management in a hospital-based nutrition department. Nutritional guidelines and survey reports of hospital evaluation programs from 2004 to 2009 were analyzed. In total, 275 hospitals in the first period and 288 hospitals in the second period were evaluated. The division of knife and chopping board use decreased from 97.2% in 2005 to 89.7% in 2008, the maintenance of a proper freezer temperature (below $-18^{\circ}C$) increased from 82.1% in 2004 to 97.7% in 2007 (88.9% to 97.4% from large hospitals and 69.8% to 86.5% from small/medium hospitals in 2005 and 2008, respectively). In tube-feeding management, the performance rate of material cold storage and the offer rate of tube-feeding were 65.9% and 94.2% in 2007, respectively. The cold storage of material, proper use within 24 hours after opening or production, and the use of an appropriate label were 47.3%, 71.2% and 67.2% in 2009, respectively. The rate of a management system for undernourished patients was 86.0% in 2007 (56.4% for large hospitals, 18.9% for small/medium hospitals) and 14.3% in 2009. In standards of nutrition support management, the performance rates of constructing a nutrition support team, the nutrition support team activity, and organizing multidisciplinary team were 66.7%, 43.6%, and 64.1% respectively, in 2004. For large hospitals, those rates were 61.1%, 36.1%, and 58.3%, in 2005, 93.0%, 62.8%, and 91.9% in 2007, and 69.2%, 43.6%, and 69.2% in 2008, respectively. The results of this study suggest standards on sanitary foodservice preparation, production, and tube-feeding production need to correspond with HACCP regulations for small/meidium hospitals in standards of a healthcare accreditation system. It will be necessary to understand the operating conditions of nutrition departments in convalescent hospitals, psychiatric hospitals, and geriatrics hospitals. As the application of accreditation is required from 2013, standards will need to be improved and continuously updated for healthcare accreditation.

STATEMENT OF PROBLEM. Despite an improved bone reactions of Mg-incorporated implants in the animals, little yet has been carried out by the experimental investigations in functional loading conditions. PURPOSE. This study investigated the clinical and histologic parameters of osseointegrated Mg-incorporated implants in early loading conditions. MATERIAL AND METHODS. A total of 36 solid screw implants(diameter 3.75 mm, length 10 mm) were placed in the mandibles of 6 beagle dogs. Test groups included 18 Mg-incorporated implants. Turned titanium implants served as control. Gold crowns were inserted 4 weeks after implant placement and the dogs were immediately put on a food diet. Implants were observed for 10 weeks after loading. Radiographic assessments and stability tests were performed at the time of fixture installation, $2^{nd}$ stage surgery, 4 weeks after loading, and 10 weeks after loading. Histological observations and morphometrical measurements were also performed. RESULTS. Of 36 implants, 33 displayed no discernible mobility, corresponding to successful clinical function. There was no statistically significant difference between test implants and controls in marginal bone levels(P=.46) and RFA values. The mean BIC % in the Mg-implants was $54.5{\pm}8.4%$. The mean BIC % in the turned implant was $45.3{\pm}12.2%$. These differences between the Mg-implant and control implant were statistically significant(P=.005). CONCLUSIONS. The anodized, Mg-incorporated implant demonstrated significantly more bone-to-implant contact(BIC) in early loading conditions. CLINICAL IMPLICATIONS. The results of this study in beagle dogs suggest the possibility of achieving predictable stability of early loaded free-standing dental implants with Mg-incorporated surface.

Consumer education which changes human value and attitude to attain practice is necessary to solve the problem of environmental, social, and economical sustainability resulted from material and present-oriented consumption and decrease the effect of consumption on the sustainabilities. However, since the present consumer education is biased toward a traditional viewpoint of economical consumption, management of allowances, and rational purchase and its teaching method still stays on memorizing, cramming and one sided lecture, consumer education containing a key value of sustainable development have not been carried out successfully, Specifically, the consumer education in an elementary school treats mainly just on environmental conservation and economical knowledge even though quite much time is arranged in every school year. So, complement of contents such as understanding of relation between natural resources and consumption and the role and responsibility of a consumer is required to emphasis the sustainable development. In this work, a student-oriented educational drama programme for consumer education is developed with respect to an familiar theme of resources such as water, wood, food, and electricity. Educational drama is an efficient teaching method for consumer education of an elementary school student since it makes students experience virtual situation and produce an interest and active participation. How to execute consumer education in an elementary school textbook was analyzed and an educational drama programme was developed and applied, and finally, the programme was qualitatively improved. The paper survey on five teachers practicing the present programme reveals that is it can be affirmatively evaluated since it is familiar to students and leads to their interests and participation. Consequently, it can be confirmed that the present programme can be effective to perform consumer education for sustainable development.

Unlike ordinary recreational facilities, an amusement park consists of various entertainment facilities, attractions, food services, souvenir shops and other attribute. The purpose of this study is to survey users´ responses to such attributes and analyze the importance and performance of each attribute, and thereby, ultimately help improve the efficiency of management and operation of the amusement parks. For this purpose, a survey was conducted of Everland users in August, 1999. 420 users were chosen by means of he systematic sampling. All the suers were asked to rate the importance of 14 attributes of Everland at the entrance and all of them were asked to do the same at the exit. As a result, it was found that the attribute rated highest by the users was ´attraction´, followed by ´service´, ´accessibility´ and ´cost´ in that order. On the other hand, it was found that the total average of importance rated for 14 attributes was 3.31, while that of performance was 3.10. As a consequence of analyzing the action grids, it was found that ´appropriateness of the circulation system´ should be improved most urgently. 7 attributes were categorized as ´keeping up good work´, and 6 ones were rated ´low priority´ in terms of improvement. There was no attribute considered to be ´possible overkill´. Meanwhile, as a result of analyzing the difference among groups in order to determine users´ response depending on their demographic and socio-economic variables, it was found that only the ´age´ variable was significant. It is expected that the results that the results of this study would be useful in determining priorities when improving amusement park facilities or their programs.

For decades, the various virtues of ${\alpha}-lipoic$ acid (ALA), a natural material synthesized in most cells, have been intensively studied and proved. Recently it was reported that ALA caused significant bodyweight reduction via appetite suppression. Unfortunately, the efficacy requires an administration over 50 mg/kg. The low bioavailability and the short plasma half life of ALA lead us to explore novel pharmaceutical dosage forms using nanoparticles. In this study, the effect of polymeric stabilizers on the bioavailability improvement of ALA nanoparticles was investigated. The reduction of particle size via nano-comminution technology was successful resulting in volume average particle sizes of 320 - 340 nm. The in vitro release rate of ALA did not reflect the decrease of particle size, possibly because of the self polymerization of ALA during nano-comminution. The type of polymeric stabilizers could not affect the release rate either. However, the in vivo food intake results of ALA showed that nano-suspensions were more effective than microparticles or a salt form. The nano-suspension containing polyvinyl pyrrolidone as the primary stabilizer and polyacrylic acid as the secondary stabilizer showed more improved efficacy for 2 hours.
