This study was made to suggest the nursing strategies for promoting the behaviors about bone mass health behaviors in order to prevent middle aged women's osteoporosis. This study was a descriptive-correlational design that also concerned to the types which improve bone mass promoting behaviors by inspecting patterns of health locus of control method out of recognizable variables of health improving models influencing on these bone mass promoting behaviors. For these purpose, data were collected by self reported questionnaire in middle school, from 158 women living in Seoul. The measuring tools used in this study about bone mass promoting behaviors and multidimensional health locus of control, were developed by author on the basis of literature review and analyzed by SPSS-PC window, into pearson's correlation, ANOVA, multiple regression, cluster analysis. Data was analyzed as follows. 1. 6 Multidimensional health locus of control scale clusters were existed. : a)cluster I (pure internal), b)cluster II(pure chance), c) cluster III(Believer in control), d), cluster IV(Type VI), e)cluster V(yea sayer), f) cluster VI(nay sayer). There were no findings of the powerful others external cluster and double external cluster. 2. The higher the value of internal health locus of control was, the better the bone mass promoting behaviors were(r=.2891, $p=.00^{**}$). The higher the value of chance external health locus of control was, the worse the bone mass promoting behaviors were(r=-.1367, $p=.00^{**}$). 3. On the basis of these relationships, 6 clusters were significantly different in the bone mass promoting behaviors(F=2.27, $p=.05^*$). The value of bone mass promoting behaviors was ranked the order of type VI>believer in control>pure internal>yea sayer>nay sayer>pure chance external highly. 4. Bone mass promoting behaviors were not significantly different as to age. Suggestion. Based on the results from the study, I would like to make some suggestions as follows. 1) To delay the loss of bone mass in middle aged women, the study on the cluster of the multidimensional health locus of control should be conducted repeatedly. 2) The tool of multidimensional health locus of control should be developed through a qualitative method adjusted on Korean' health culture.

The aim of this study was to investigate intake of health foods and supplements and its associated factors in middle and old-aged adults in order to contribute to health promotion of Korean population by providing a guide for proper use of health foods and supplements. About 69% of the subjects reported that they were currently taking health foods and supplements or had experiences of having them in the past, whereas 31.2 % reported they had never taken them. The most commonly used type of health foods and supplements was vitamin C as reported by 41.8% followed by others such as lactobacillus products, multi-vitamins, tonic medicine and cardiotonic drug, artificially processed Ginseng foods, vitamin B complex, enzyme supplement, calcium, aloe, apricot extract products, chitosan products, loyal honey, squalene, refined fish oil and iron products. The major reason for taking health foods and supplements was 'to protect the weak constitution' with 155 (42.1%) responses, and the motive for the intake was the suggestion from family-relatives with 235 (63.9%) responses, and the place of purchase was pharmacy with 140 (38.0%) responses, the average monthly expense was 20,000-40,000 won with 140 (26.2%) responses, and effects after the intake was 'so and so' with 180 (33.6%) responses as the highest. More health foods and supplements were consumed as age and education were statistically significantly increased (p<0.05). For health and lifestyle and the intake of health foods and supplements, perceived health status, the presence of illness, and the presence of health management were statistically significant (p<0.05). Male subjects than female subjects and the 30s than the 405 and 50s were appeared to have poorer dietary behaviors (p<0.05). For the health locus of control and the intake of health foods and supplements, the health locus of control score was 22.82 for consumers and 22.79 for non-consumers, showing no significant difference. Logistic regression analysis was performed to find out major factors that affect the intake of health foods and supplements, in which gender, education, smoking, perceived health status, the presence of illness, and health management were significant to the intake of health foods and supplements. It is shown that subjects with perception and attitude of 'health foods and supplements are useful in health maintenance and disease prevention' and 'the information and variety for health foods and supplements are great' have higher probability of taking health foods and supplements.

본 연구에서는 다시마의 생리 활성과 기능성을 이용한 고부가가치 식빵의 제품화 가능성을 탐색할 목적으로 다시마 가루를 2.5%,5%, 7.5%첨가한 식빵을 제조하여 식빵의 물리화학적 특성과 관능검사를 실시하였으며 가장 적절한 다시마 가루의 첨가 수준을 알아보고자 하였다. 그 결과를 요약하면 다음과 같다. 다시마 가루를 첨가한 반죽의 제빵 적성을 알아보기 위하여 온도 27$\pm$1$^{\circ}C$, 상대 습도 75%의 발효 조건에서 90분간 반죽의 발효팽창력을 측정한 결과, 다시마가루의 첨가량이 증가할수록 팽창력 이 감소하는 것을 알 수 있었다. 그러나 2.5% 다시마 첨가 수준에서는 대조군과 비슷한 발효팽창력을 나타내었다. 다시마 가루 첨가 식빵의 부피는 다시 마 첨가량이 증가할수록 감소하였으나 2.5% 다시마 첨가시까지는 부피에 거의 영향을 미치지 않았다. 다시마첨가 식빵의 무게는 크게 차이는 나타나지 않았으나 7.5% 첨가시에는 유의적으로 감소하였다. 색도 측정 결과 식 빵 내부의 명도를 나타내는 L값, 적색도를 의미하는 a값은 다시마가루의 첨가량이 증가함에 따라 유의적으로 감소하였고 황색도를 나타내는 b값은 다시마 가루 첨가량이 증가함께 따라 증가하였다. 즉, 다시마 가루를 첨가할수록 명도는 줄어들고, 적색이 감소하면서 황색이 증가하는 경향을 나타내었다. 식빵의 조직감을 보면 다시마 첨가량이 많아질수록 견고성, 부서짐성은 증가하였으나 점착성, 탄력성, 응집성은 다시마 첨가량에 따른 유의적인 차이가 없었다. 관능검사 결과는 20대 여대생과 50대 주부의 두 집단으로 나누어 분석하였는데 두 집단간에 다시마 가루 첨가 식빵에 대한 기호가 유의적으로 다른 것으로 나타났다. 20대 여대생의 경우 다시마 첨가량이 증가할수록 기호도가 감소하였으나 2.5% 다시마 첨가군에 대한 평가는 전반적으로 좋게 나타났다. 반면 50대 주부들의 경우에는 2.5% 다시마 첨가한 식빵에 대한 평가점수가 대조군보다 높았다. 5% 다시마 첨가에서도 대체적으로 대조군과 비슷한 기호도를 나타내었다. 이상의 결과를 종합해 보면 다시마 가루를 2.5% 첨가한 식빵을 제품화하면 일반적인 식빵에 비해 다시마의 생리 효능을 활용하면서 소비자들의 높은 호응을 기대해볼 수 있을 것으로 사료된다.

Purpose - This study analyzes loading efficiency by loading pattern for package standardization and reduction of logistics costs, along with the creation of revenue for the revenue review panel (RRP) of Membership Wholesale Clubs (MWC). The study aims to identify standard dimensions that can help improve the compatibility of the pallets related to display patterns preferred by the MWC and thereby explore ways to enhance logistics efficiency between manufacturers and retailers through standardization. Research design, data, and methodology - The study investigates and analyzes the current status based on actual case examples, i.e., manufacturer A and Korea's MWC (A company, B company, and C company), and thus devises improvement measures. To achieve this, the case of manufacturer A delivering to MWC was examined, and the actual pallet display patterns for each MWC were investigated by visiting each distribution site. In this study, TOPS (Total Optimization Packaging Software, USA) was used as the tool for pallet loading efficiency simulations the maximum allowable dimension was set to 0.0mm to prevent the pallet from falling outside the parameters, and the loading efficiency was analyzed with the pallet area. In other words, the study focused on dimensions (length x width x height) according to the research purpose and thereby deduced results. Results - The analysis of pallet loading patterns showed that the most preferred loading patterns for loading efficiency according to product specification, such as pinwheel, brick, and block patterns, were used in the case of the general distribution products, but the products were configured with block patterns in most cases when delivered to MWCs. The loading efficiency by loading pattern was analyzed with respect to 104 nationally listed standard dimensions. Meanwhile, No.51 (330 × 220mm) of KS T 1002 (1,100 × 1,100mm) was found to be the dimension that could bring about an improved loading efficiency, over 90.0% simultaneously in both the T-11 and T-12 pallet systems in a loading pattern configuration with the block pattern only, and the loading efficiency simulation results also confirmed this as the standard dimension that can be commonly applied to both the T-11 pallet (90.0%) and the T-12 pallet (90.7%) systems. Conclusions - The loading efficiency simulation results by loading pattern were analyzed: For the T-11 pallet system, 17 standard dimension sizes displayed the loading efficiency of 90.0% or more as block patterns, and the loading capacity was an average of 99.0%. For the T-12 pallet system, 35 standard dimension sizes displayed the loading efficiency of more than 90% as block patterns (the average loading efficiency of 98.6%). Accordingly, this study proposes that the standard dimensions of 17 sizes with the average loading efficiency of 99.0% should be applied in the use of the T-11 pallet system, and those of 35 sizes with the average loading efficiency of 98.6% should be reviewed and applied in the use of the T-12 pallet system.

The purpose of this study was to determine the effect of finish line design, amount of incisal reduction, and loading condition on the stress distribution in anterior all-ceramic crowns. Three-dimensional finite element models of an incisor all-ceramic crown with 3 different finish line designs : 1) shoulder with sharp line angle 2) shoulder with rounded line angle 3) chamfer : and 2 different incisal reductions : 2mm and 4mm were developed. 300 N force with the direction of 45 degree to the long axis of the tooth was applied at 3 different positions : A) incisal 1/3, B) incisal edge, C) cervical 1/5. Stresses developed in ceramic and cement were analyzed using three-dimensional finite element method. The results were as follows : 1. Stresses were concentrated in the margin region, which were primarily compressive in the labial and tensile in the lingual. 2. Stresses were larger in the area near line angle than on the crown surface of the margin region. In case of shoulder with sharp line angle, stresses were highly concentrated in the porcelain near line angle. 3. At the interface between porcelain and cement and at the porcelain above the margin on crown surface, stresses were the highest in chamfer, and decreased in shoulder with sharp line angle and shoulder with rounded line angle, respectively. 4. At the interface between cement and abutment on crown surface, stresses were the highest in shoulder with sharp line angle, and decreased in shoulder with rounded line angle and chamfer, respectively. 5. The amount of incisal reduction had little influence on the stress distribution in all-ceramic crowns. 6. When load was applied at the incisal edge, higher stresses were developed in the margin region and the incisal edge than under the other loading conditions. 7. When load was applied at the cervical 1/5, stresses were very low as a whole.
