The objectives of this study were to classify the types of elderly households and to compare the characteristics of their dietary lifestyle. Panel data surveyed by Korea Rural Economic Institute (KREI) for Food Purchase Attitudes over three years (2019 - 2021) were utilized for the analysis. Through a factor analysis, five common factors were extracted out of 19 basic variables related to dietary style, which indicate two kinds of consumer competency index (safe diet, traditional diet) and three kinds of purchase frequency (healthy food, meat & fish, fresh seafood). Applying the cluster analysis method, by using socioeconomic variables along the five common factors, elderly households aged 60 or older were grouped into four types. As a result, Type 1 elderly households accounted for 50.8%, Type 2 for 16.2%, Type 3 for 27.8%, and Type 4 for 5.2% out of all 870 elderly households. Type 1 is characterized as a low-income vulnerable class with a poor diet, Type 2 as a middle-income class with a healthy food-oriented diet, whereas Type 3 was classified as a middle-income class with a meat-oriented diet, and Type 4 as a high-income class with diverse dietary culture. It is necessary to expand the agri-food voucher pilot project to the entire country and also increase the monthly subsidy for the Type 1 elderly households. Implementing community kitchen projects for elderly single-person households, promoting senior internships by providing incentives to companies that employ retirees, the provision of education by local governments on a safe and balanced diet for Types 2 and 3, and the promotion of an elderly-friendly social environment are also recommended.

The purpose of this study was to identify structural patterns in the subjectivity of Taegyo in pregnant woman and to provide a basis for nursing interventions. Thirty pregrant women were the subjects of this study. They were in the gestation period of pregnancy between 12 weeks to five days post partum and they lived in the city of Taejon. The research method employed Q-methodology which is based on self-psychology and abductive logics. The results revealed three different types of the Taegyo ; 1) Peaceful mind type, listening to music and appreciation of art for quietness of mind and also the support and concern of husband. 2) Self control type, recognizes herself as a pregrant woman and trys to do her works spontaneously and also adapt herself to changing of circumstances. 3) Dependent oriented type, needs absolute help from the surroundings under the specific condition of pregnancy. This results show that investigating the specific experience, characteristic and structure of the Taegyo of a pregnant woman can be used as a part of the nursing assessment and also provides useful basic data of nursing interventions during pregnancy.

The aim of this paper is to suggest basic guidelines for the urban park development policy in Taegu. This research is mainly based on university students' essay on ＜private inquiry of urban park in Taegu＞. Talsong Park, the most popular site for the students' essay, was selected for the purpose of the study. The research focused on the general images of the park, negative images of the park and aspirations and demands for the park in relation with Talsong Park redevelopment policy. The research of this result suggested that the renovation of Talsong Park from zoo-oriented park to the historic ＆ cultural park status. The other main suggestion was consideration of public participation from the planning stage for the betterment of park management. In addition, the importance of environmental education for the local people was stressed in order to enhance public awareness of environment for the solution of our common environmental problems in relation with Local Agenda 21.

The anti-plane shear problem of bonded elastic materials containing a crack at an arbitrary angle to the graded interfacial zone is investigated in this paper The interfacial zone is modeled as a nonhomogeneous interlayer of finite thickness with the continuously varying shear modulus between the two dissimilar, homogeneous half-planes. Formulation of the crack problem is based upon the use of the Fourier integral transform method and the coordinate transformations of basic field variables. The resulting Cauchy-type singular integral equation is solved numerically to provide the values of mode 111 stress intensity factors. A comprehensive parametric study is then presented of the influence of crack obliquity on the stress intensity factors for different crack size and locations and for different material combinations, in conjunction with the material nonhomogeneity within the graded interfacial zone.

Objectives: This study was to explore how elderly with chronic disease in a health management program managed their health and to describe their health management strategies. Methods: The data were collected through in-depth interviews, with a purposeful sample of twelve in an urban community. The collected information was analyzed through grounded theory approaches by Strauss and Corbin. Results: Though open coding process, 35 concepts, 17 subcategories, 8 categories were identified. As for the participation experience process, four stages had surfaced, namely, 'Perception of chronic disease', 'Concerned about health', 'Developing life pattern', 'Restoring health'. These processes were within 'Restoring Health Equilibrium', core category. Consequently, the participants revealed in restoring relationship-oriented life and settling in family-focused life. Conclusions: These findings have implications for the understanding of health promotion for the elderly with chronic diseases and contributing to make a basic data for developing elderly health management program.

High pressure X-ray diffraction study was carried out on a polycrystalline graphite to investigate the phase transition(s) at room temperature. Energy dispersive X-ray diffraction method was employed using a Mao-Bell type diamond anvil cell with an Wiggler synchrotron Radiation at the National Synchrotron Light Source. Sodium chloride power was used as the internal pressure sensor for the high pressure determinations as well as the pressure medium for quasihydrostatic pressure environment. Graphite transforms into a hexagonal didose not agree with the previously reported observations and this phase persists when pressure is released down to 0.1 MPa. This result dose not agree with the previously reported observations and this discrepancy would be due to the kinetics in phase transition as well as the uniaxially oriented pressure field in the diamond anvil cell.

In order to investigate the effect of the interface on GMR, [NiFe(25 ${\AA}$)/Cu(24${\AA}$)]$_2$/Si thin film was epitaxially grown on HF-treated Si (001) substrate using a DC magnetron sputtering method. Typical GMR effects could be observed in epitaxial film with a weak antiferromagnetic exchange coupling while non epitaxial film showed unsaturated and broad MR curves probably due to inter-diffusion between NiFe and Cu layers. Ferromagnetic resonance (FMR) experiment showed two distinct absorption peaks in all films. Each peak was revealed to come from each NiFe layer with different magnetic property. In FMR measurement very clear interface in epitaxial films could be confirmed by a lower value of line width (ΔH) and higher M$\sub$s/ of epitaxial film than those of non epitaxial films, respectively.

This paper concentrated on the ultimate uniaxial compressive strength of stiffened panel with opening under lateral load and also studied the design-oriented formulae. For this purpose, three series of well executed experiments on longitudinal stiffened panel with rectangular opening subjected to the combined load have been selected as test models. The finite element analysis package, ABAQUS, is used for simulation with considering the large elasticplastic deflection behavior of stiffened panels. The feasibility of the numerical procedure is verified by a good agreement of experimental results and numerical results. More cases studies are executed employing nonlinear finite element method to analyze the influence of design variables on the ultimate strength of stiffened panel with opening under combined pressure. Based on data, two design formulae corresponding to different opening types are fitted, and accuracy of them is illustrated to demonstrate that they could be applied to basic design of practical engineering structure.
