Primary school is regarded as an important period when many health-related behaviors and life-styles begin to be formed. Acquiring them through school heath education has a strong influence on the health promotion of not only the family but also the community. Primary school health education in Korea has a systematic flaw in that health-related subjects are divided and taught under various subjects in primary school. In order to develop a proper school health curriculum, it is essential to assess what is currently being taught. In this study the current health education of the 6th grade primary curriculum was investigated to improve school health education. The purpose of this study is to identify the health education contents and time in textbooks of the 6th grade primary school curriculum. In this study, the textbooks & teacher's teaching manuals of the 6th grade curriculum were analyzed with a health instruction framework for Korean schools developed by the Korean Nurse Association & Korean School Health Education Association in 1993 and health care framework for health education curriculum presented by Kim in 1991. The results are as follows ; 1) Health education hours of the curriculum are 206 hours, about 34.3 hours a year. 2) The contents of health education were divided into nine subjects at primary schools. Organizing principles of learning experience(eg, integrity, sequence and continuity) were not considered sufficiently. The physical education & natural science subjects include a lot of health education contents. 3) The major content areas are community & environmental health areas and daily healthy life areas. 4) The major areas at each grade level are daily healthy concerns and safety & first-aid 5) The remarkable contrast to the 5th primary school curriculum are that environmental health is offered to the first grade step by step, and that drug use & abuse and mental health education are included in the 6th primary school curriculum. 6) The main contents of health education in 1st, 2nd. and 3rd grade curricula consist of treatment & recovery health functions. Those of the 4th grade curriculum consist of treatment & recovery health functions, and daily healthy life functions. Those of the 5th grade consist of growth & development functions. Those of the 6th grade consist of treatment & recovery health, growth & development functions. Most health care functions belong to physical health care. The results above suggest that we put together the divided contents of health education and manage them on the basis of systematic integration.

Purpose: The purpose of this study was to propose a theoretical model of hope commonly held by the cancer patients just after surgery, under the assumptions that hope of those patients is not only realistic and disease oriented but in dialectical circulation. Method: A theoretical model was generated through 4 steps: exploring a hope structure by synthesizing the relevant hope structures expressed in Kim and Tae's studies, in-depth literature review, examining the meanings of the concepts consisted of the structure in use and their causal relations in logical adequacy, proposing a theoretical structure through synthesizing the causal relations, and diagramming the structure. Results: The proposed theoretical model involves concepts such as Cancer Related Uncertainty (CRU), Efforts to Find out the Possibility of Cure or Recovery (EFPCR), and Hopefulness or Hopelessness. The 'EFPCR' is stipulated as 'Behaviors Related to Looking for Evidences or Cues (BRLEC)' and 'Formation of Cognitive Schema (FCS)'. In the model, Hopefulness is directly influenced by 'CRU in low', which is affected by 'FCS in good' from the result of EFPCR started with 'CRU in increase' while 'CRU with increase' from the result from EFPCR has direct effect on Hopelessness. Conclusion: The theoretical model would be used to enhancing hope of the cancer patients in post-operation.

The purpose of this study was to investigate the influencing factors on health behavior among patients with coronary artery disease. Method: The subjects were 95 patients who visited the out-patient department of a university hospital for follow-up. The four health belief concepts (motivation, benefit, barrier, seriousness), general self-efficacy, health behaviors on medication, diet, exercise, stress management, smoking, and drinking were measured. Result: There were significant differences in the health behavior scores of subjects according to family support and the experience of surgical procedure. Subjects were found to have a high degree of compliance in taking medication. However subjects reported the lowest degree of compliance in regular exercise. In the multiple regression analysis, surgical procedure and motivation were significant predictors to explain diet. Motivation and barrier were significant predictors to explain exercise. Self-efficacy, motivation and family support were significant predictors to explain stress management. Family support and seriousness explained 16% of variance in drinking. Also, family support explained 30% of variance in smoking. Conclusion: Since predicting factors on each health behavior indicator were different, then nurses should consider these differences to construct strategy enhancing patient's recovery.

Chitosan and CA/BTCA were employed in order to induce crosslinking in the fiber for the improvement of wrinkle recovery of the cotton fabrics and the endowment of anti-microbial functions to the fabric. The treated fabrics were dyed by using reactive dyestuff and their dyeing behaviors were investigated. As a result, the fabric treated with chitosan only exhibited more dye-uptake amount than the untreated fabric, and the treated and untreated fabrics together showed excellent light-fastness and wash-fastness. In the cases that CA or BTCA was added to the chitosan, the CA-treated showed better dye-uptake and dyeing properties as light-fastness than the BTCA-treated. In conclusion, it is possible to maintain the dye-uptake level at reduced treatment cost when the CA is employed as a substitute cross-linking agent for BTCA.

Effect of heat-treatment on the microstructure and recrystallization behavior of pure Zr was studied. The specimens were prepared under the various annealing temperatures from $400^{\circ}C$ to $800^{\circ}C$ and times from 300 to 5000 minutes after vacuum arc remelting. The recrystallization behavior was observed by a polarized optical microscope, TEM and micro-vickers hardness tester. With increasing the annealing time, the temperature region of hardness drop moved to the lower temperature region due to the recovery and recrystallization behaviors at the lower temperature. The recrystallization of cold-worked pure Zr was completed between 450 and $600^{\circ}C$. The size of recrystallized grain increased at $700^{\circ}C$ for 600min. Activation energy(Q) of pure Zr measured by the time for constant fraction technique was 78 KJ/mol.

A highly dispersed W/O emulsion of silicone oil (cyclomethicone)/water system was prepared with a nonionic surfactant. The surface and interfacial tension between the oil and water were characterized in terms of the droplet size distribution and viscosity change of the emulsion. When the dispersed phase concentration was relatively high, the viscosity of the emulsion was rapidly increased and the droplet size of the emulsion was decreased. The rheological behavior of the emulsion system showed non-Newtonian and shear thinning phenomena depending upon the content of the dispersed phase. The droplet size of the emulsion was decreased with increasing surfactant content and water concentration. The relative viscosity of the emulsion was better predicted with the Choi-Schowalter model than with the Taylor model. The value of the complex modulus increased with increasing surfactant concentration. The linear viscoelastic region was expanded with a dispersed phase concentration. According to the change in the viscosity, the behavior was classified into three distinct regions: [I] linear viscoelastic, [II] partially viscoelastic, and [III] viscous. The creep/recovery behaviors in each region were characterized.

With Increasing importance of electroless nickel plating technology in many fields such as electronic and automobile industries, the treatment of the spent baths is becoming a serious problem. These spent baths contain iron and zinc as impurities, organic acids as complexing reagents, and phosphonate ions as oxidized species of tile reducing reagent. as well as several grams per liter of nickel. The spent baths are currently treated by conventional precipitation method. but a mettled with no sludge generation is desired. This work aims at establishing a recycling process of nickel from tile spent baths using solvent extraction. Extraction behaviors of nickel. iron. and zinc in various 쇼pes of real spent baths are investigated as a function of pH using LIX841, di (2-ethylhexyl)phosphoric acid (D2EHPA), and PC88A as tile extractants. Nickel is extracted by LIX84I at the equilibrium pH of more than 6 with high efficiency. For the weakly acid baths. iron and zinc are extracted by D2EHPA or PC88A without adjusting the pH of the baths leaving nickel in the aqueous phase. Stripping of nickel from LIX84I with sulfuric acid is also investigated. It is shown that concentrated nickel sulfate solution (> 100 ㎏-Ni/㎥) is obtained. This solution can be reused in the electroless plating process. Based on these findings, flow sheets for recovering nickel from the spent baths are proposed.

Warning phase of disaster is a critical period in determining the likely survival of threatened citizens. Elderly requires special attention primarily because they tend to be uncompliant and less likely to cooperate with authorities. But there is much less research on how elderly respond to disaster warnings, while there is a strong consistent empirical literature on older citizen in the recovery periods of disaster. The purpose of this study is to examine coping behavior of elderly when they are at risk of disaster. Data were collected from 130 senior citizens aged over 60 who are residing in Pyungchang and Injae in Kangwon province which had damaged due to heavy rain in 2006. Perry & Lindell(1997)'s index, a series of six categories that represent coping behaviors which progressively approximate the action of evacuating was used : do nothing(1), check environmental cues for evidence of a threat(2), engage in threat-specific property protection(3), engage in protective action for personal safety(4), prepare to evacuate(5), evacuate the areas as instructed in the warning(6). Almost respondents(69.2%) chose the level 6(51.5%) and level 5(17.7%). This proves the elderly are not uncompliant or uncooperative population. Furthermore, this finding emphasizes the importance of public warning in case of disasters. And 13.8% of total respondent checked level 1 for their reaction.
