Purpose: The purpose of this study was to examine the differences of the process of change, decision making, self-efficacy and perception of subjective health according to the stages of exercise behaviors suggested by transtheoretical models among older adults. Method: The subjects consisted of 291 older adults. Trained research assistants interviewed the older adults using structured questionnaires. ANOVA analyses with post hoc test were used to examine the mean differences for each stage of exercise behavior using SPSS for windows. Result: The subjects were divided into five stages of exercise behavior: 24.4% precontemplation, 12.4% contemplation, 17.9% preparation, 12.4% action, 33.0% maintenance stage. There were significant differences in process of change, decision making, self-efficacy and subjective health perception according to the exercise stage of change. 'Self-liberation' and 'stimulus control' were important strategies for intention of exercise, while 'reinforcing management' for the actual practice of exercise. 'Self-efficacy' was an effective strategy to change older adults from pre-contemplation to preparation stage. Conclusion: For exercise intervention, older adults should be classified into groups according to their stages of exercise behaviors and provided effective individualized intervention depending on their stage.

The aim of this study was to identify the attitude of nursing students' toward death using Q-methodology and to obtain baseline data to improve nursing students' education program on death. Twenty-nine participants at a college classified 40 Q-statements on a one to nine scale. The resultant Q-sort was a matrix representing the participant's operant subjectivity on the issue under consideration. The results of above procedures were analyzed by PQ Method. The results revealed that there are three types of perception about nursing students' attitudes toward the death. The categories were labeled positive-perspective, pain-avoid and preparation-deficiency. Positive-perspective individuals have a positive sense of their life and death. Thus, they would not fear death, believing in an after-life world, while being positive towards donation of intestines after death. Pain-avoid individuals hope life and death without pain. Preparation-deficiency individuals are unprepared to die. In conclusion, this study discovers three types of the perception about nursing students' attitudes toward the perception of death. By identifying the nature of each of these types, this study can be useful to develop efficient strategies for education program on death.

Recently, polymer-metal composite (IPMC)-based ionic artificial muscle has been drawing a huge attention for its excellent soft actuator performance having outstanding soft actuator performance with efficient conversion of electrical energy to mechanical energy under low working voltage. In addition, light, flexible and soft nature of IPMC and high bending strain response enabled development of versatile sensor application in association with soft actuator. In this paper, current issues of IPMC were discussed including standardizing preparation steps, relaxation under DC bias, inhibiting solvent evaporation, and improving poor output force. Solutions for these drawbacks of IPMC have recently been suggested in recent studies. After following explanation of the IPMC working mechanism, we investigate the main factors that affect the operating performance of the IPMC. Then, we reviewed the optimized IPMC actuator fabrication conditions especially for the preparation process, additive selection for a thicker membrane, water content, solvent substitutes, encapsulation, etc. Lastly, we considered the pros and cons of IPMCs for sensor application in a theoretical and experimental point of view. The strategies discussed in this paper to overcome such deficiencies of IPMCs are highly expected to provide a scope for IPMC utilization in soft robotics application.

Purpose: The purpose of this study was to investigate differences in smoking related characteristics and psychological features of coronary artery patients by the stages of change in smoking cessation behaviors. Method: Subjects for this survey were 97 patients who were smoking when doctors diagnosed them to have coronary artery diseases. Result: Subjects were distributed 21.6% in precontemplation stage, 24.7% in contemplation stage, 17.5% in preparation stage, 19.6% in action stage, and 16.5% in maintenance stage respectively. The numbers of previous attempts to quit smoking of subjects in precontemplation stage(mean=3.00, SD=3.71) and contemplation stage(mean=2.63, SD=2.32) were significantly lower than that of subjects in preparation stage(mean=5.82, SD=6.20). Benefit scores of subjects in maintenance stage were significantly greater than those of subjects in precontemplation stage. Self-efficacy, barriers, seriousness, and nicotine dependency were not significantly different by the stages of change. Number of signs and symptoms related to smoking which subjects were experiencing were not significant by the stages of change too. Conclusion: Future intervention programs for smoking cessation should be focused on the strategies to enhance the realization of health benefits that patients might acquire from smoking cessation.

The purpose of the study was to investigate assisted living residents' perception of foodservice experience using a qualitative approach. A total of 14 residents who lived in assisted living units of a continuing care retirement community participated in interview sessions. The interviews were semi-structured with open-ended questions. The interviews were transcribed and coded to identify themes from the responses. The residents perceived the availability of choices, variety of foods, and service positively, but expressed concerns about food preparation, food quality, and repetitive menus. They were particularly concerned with tough and dry meats. The foodservice department should consider the older residents' ability to chew and their changing taste buds when determining quality of food purchased and preparation methods. The residents considered the service pleasing and described it as satisfactory. They stated that the service staff was friendly but needed more training in proper service techniques. Communication between the foodservice department and the residents was an area to be improved. The foodservice department should increase the residents' involvement in the menu planning and evaluation of the foodservice on a routine basis. Foodservice managers and dietitians working for the older adults can utilize the findings of the study to identify strategies to improve foodservice at their facilities

The food and nutrition system is a network of processes linking agriculture, food, eating, nutrition, and health. The system includes a series of nine stages (production, processing, distribution, acquisition, preparation, consumption, digestion, transport, and utilization) and two types of contexts (biophysical and sociocultural). Analysis of whole food and nutrition systems provides information about the structure and processes involved in the complete scope of food and nutrition, assisting in the identification of ″upstream″ influences and ″downstream″ consequences in the system. The current analysis gathered existing data about the food and nutrition system in South Korea from public sources and professional publications, and interpreted that information to consider how different elements of the system contribute to health. The findings revealed that South Korea has substantial domestic food production and processing supplemented by imports, widespread food distribution in markets and a growing number of Korean and Western restaurants, a relatively low percentage of household income spent on food, growing use of new food preparation methods such as microwave ovens, a rice/vegetable/fish based three-meal consumption pattern, few recorded digestive problems, increasing calorie storage as body fat, and a relatively low chronic disease prevalence compared to other developed societies. Examination of the full scope of the food and nutrition system provides a broad perspective using whole system thinking that can identify potential strategies for future research and intervention.

There exist two interesting phenomena in making seafood products from surimi. When salted surimi is kept at a constant low temperature $(4\~40^{\circ}C)$, its rheological properties change from sol to gel, which is called 'setting'. Seafood processors can exploit changes that occur during setting in preparation of surimibased products, because heating at high temperatures, after the pre-heating during the setting process, enhances the gel-strength of salted surimi. Contrarily, when salted surimi or low-temperature set gel is heated at moderate temperatures $(50\~70^{\circ}C)$, a deterioration of gel is observed. The phenomenon is termed 'modori'. In the modori temperature range, heat-stable cysteine proteinases such as cathepsin B, H, Land L-Iike hydrolyze the myosins responsible for gel-formation, resulting in gel weakening modori. This article reviews molecular events occurring during gel setting that improve the quality of surimi-based products, and inhibition of modori by applying proteinase inhibitors. Application of recombinant protein technology to surimi-based products is introduced and its prospects for practical use are discussed.
