This study aims to provide definitions and standardization for necessities that elderly people can use conveniently and properly in their daily lives and classify necessities for different purposes. First, standard terminologies were defined by reviewing the literature and the relevant laws related to daily necessities for the elders. Secondly, a concept for necessities for the elders was also defined through consultation with experts. Lastly, the elderly's necessities were selected and classified. The elderly's necessities are defined as aids that ordinary elderly people in normal aging process need for the purpose of the convenience of life and aids they wear or use to maintain or improve their health. In this study, the elderly's necessities are divided into three categories: necessities of health, necessities of Oriental medical aids and necessities of daily living. Each category is further classified as follows: Necessities of health include aids for personal medical treatment, aids for personal care and protection and aids for recreation. Necessities of Oriental medical aids include aids for personal medical treatment, aids for personal care and protection and others. Necessities of daily living include aids for personal care and protection, aids for personal mobility, aids for housekeeping, furnishings, aids for communication, information and signalling, aids for handling products and goods and aids for recreation. The classification of the elderly's necessities in this study can be used as basic information for further studies of demand for necessities for the elderly. The results will lay the foundation for a standardization system for the elderly's necessities and the development of silver industry.

A chemical batch tests were conducted to evaluate if microwave heating enhances phosphorous release from waste activated sludge (WAS) at pH 2.5, 5, 7, 9 and 11. Polyphosphate-accumulating organisms have a unique physiological feature, which releases intracellular polyphosphate granules when they are exposed under high temperature environments. Microwave irradiation was found to encourage large amount of phosphorus release from WAS, depending on pH and temperature conditions. Most of phosphorus was released below $59^{\circ}C$ within 30 min. A marked increase in phosphorus release was observed under alkaline or acidic conditions. However, based on control tests for phosphorus release under different pH conditions without microwave heating, the largest amount of phosphorus released by microwave irradiation was found at pH 7, followed by 5, 9, 11. On the other hand, crystallization was conducted to obtain magnesium ammonium phosphate (MAP) from phosphate released by microwave heating at pH 7. X-ray diffraction analysis confirmed that the recovered crystalline materials were MAP. MAP is an environmentally friendly fertilizer, which slowly releases ammonia and phosphorus in response to the demand of plant root. Thus, the recovered MAP as a phosphate fertilizer is fully expected to play a important role in the reduction of agricultural non-point pollution.

Angelica gigas Nakai (danggui) is a popular herb which has been used as a blood-building decoction for recovery from weakness in the Chinese medicine. Its demand increased in functional foods and pharmaceutical industries. For its hygiene, fumigation has been used, but the use of fumigants are going to be prohibited for food processing. In order to investigate gamma irradiation technique for hygiene of danggui, the immunomodulation activity of danggui after irradiation was examined. The water extract of irradiated danggui showed a strong mitogenic effect on splenocytes in vitro to the same level of lipopolysaccharide (LPS) and phytohemagglutinin (PHA). The effect was not different from that of non-danggui. It was tested whether there was any difference between irradiated and non-irradiated danggui in effects on the secretion of antibodies and graft versus host reaction in vivo. It turned out that intraperitoneal (i.p.) administration of the extract of irradiated danggui for 4 days remarkably increased the number of antibody-secreting cells in mice injected with sheep red blood cells (SRBC). Splenomegaly, due to graft versus host reacton, was also increased after 7 days i.p. administration of the extract of danggui in mice injected with allogeneic splenocytes. In these two in vivo test, the effect were not different from those of non-irradiated danggui. These results indicated that immunomodulation activity of danggui might be preserved after irradiation. In the other experiments (data not shown), the irradiated danggui was stable in active component analysis and safe in genetic toxicity test. In further research, the stability in other physiological activity of irradiated danggui will have to be proved before practical application of irradiation for hygiene.

This study was conducted to help oriental medical prevention program policy for improvement of public health in a local community. We have researched respiratory diseases and demands for oriental medical cold preventing therapy of some residents in Chung-Buk. We have conducted individually face-to-face interviews through standardized questionnaires to 141 residents of two towns (76 in Haeng-jung, 65 in Gu-mi) under the jurisdiction of Chung-won Public Health Center. The senior aged over 65 was 53.9%, which was a little more than the average senior age. The rate which could be diagnosed as a disorder of lung function was 2.97% by Lung Function Test. The participants diagnosed as Asthma accounted for 17.9% by Symptom Based Easy Asthma Diagnosis of Easy Asthma Management(EAM). The participants who had intentions of participating in oriental medical cold preventing therapy accounted for 58.6%. And among the oriental medical cold preventing therapy the preference for acupuncture and moxibustion was 77.1 %, which was much higher than any other thing. It is thought that people still have little understanding about the oriental medical cold preventing therapy. Therefore it is considered that the Korean government should try to establish well-organized cold preventing system on the basis of Oriental Medical theory for a local community.

With the introduction of the 40 hours workweek system, an intensive discussion was made among relevant departments. Building facilities does not necessarily guarantee more leisure activities and higher satisfaction for the public. It is essential to draft at the trend of leisure policy in Japan and learn from the experiences to set the policy direction best fitting future changes in Korea, as Japan has gone through comprehensive changes ahead of us. With this understanding, this study analyzed key leisure policies of Japan and examined the trend of changes of time. The followings are the findings of the research. First, Japan's leisure policies could be categorized into five stages and six terms. Second, leisure policies in Japan are being established as a local welfare system, not in the context of industrial perspective, to help people in local community. This is to make voluntary move by eliminating the factors that restrict social demand with an effort to expand leisure time and to secure and enhance access to leisure space. Third, Neighborhood leisure space has taken the center stage, in an effort to seek solutions to the issues of improving space utilization, restoring local community and encouraging participation of local residents. The conclusion drawn from the research is as follows. It is required to recommend the use of the specific term 'leisure' for leisure policies in Korea and for leisure space policies in Korea that are now facing sociocultural challenges similar to the ones emerging in Japan, measures are required to improve physiological access of local residents including information promotion, lifetime education and relationships enhancement along with the establishment of neighborhood leisure space.

Regulation of alkaline-resistant laccase from Perenniporia tephropora KU-Alk4 was proved to be controlled by several factors. One important factor was the initial pH, which drove the fungus to produce different kinds of ligninolytic enzymes. P. tephropora KU-Alk4 could grow at pH 4.5, 7.0, and 8.0. The fungus produced laccase and MnP at pH 7.0, but only laccase at pH 8.0. The specific activity of laccase in the pH 8.0 culture was higher than that in the pH 7.0 culture. At pH 8.0, glucose was the best carbon source for laccase production but growth was better with lactose. Low concentrations of glucose at 0.1% to 1.0% enhanced laccase production, while concentrations over 1% gave contradictory results. Veratryl alcohol induced the production of laccase. A trace concentration of copper ions was required for laccase production. Biomass increased with an increasing rate of aeration of shaking flasks from 100 to 140 rpm; however, shaking at over 120 rpm decreased laccase quantity. Highest amount of laccase produced by KU-Alk4, 360 U/mL, was at pH 8.0 with 1% glucose and 0.2 mM copper sulfate, unshaken for the first 3 days, followed by addition of 0.85 mM veratryl alcohol and shaking at 120 rpm. The crude enzyme was significantly stable in alkaline pH 8.0~10.0 for 24 hr. After treating the pulp mill effluent with the KU-Alk4 system for 3 days, pH decreased from 9.6 to 6.8, with reduction of color and chemical oxygen demand at 83.2% and 81%, respectively. Laccase was detectable during the biotreatment process.

Purpose: The purpose of this study was to identify the effects of brain-wave biofeedback training nursing intervention (NFT) upon enhancing self-regulation response in adolescence with emotional behavior problems in school. Methods: A quasi-experimental design was conducted. The participants were assigned to the experimental group (n=24) or the control group (n=24). The experimental group additionally received NFT. The NFT was conducted 10 sessions for 30 minutes per session with the band reward and inhibit training which matched their Quantitative Electroencephalography (QEEG), participant's demand and chief complaint. Data were collected with QEEG and heart rate variability (HRV) in physiological response, self-efficacy in cognitive response, depression in emotional response, impulsivity and delay gratification in behavioral response of self-regulation. Results: The general characteristics and the pre-test scores of two groups were all homogeneous. The experimental group was reported to be significantly higher in QEEG homeostasis, HRV homeostasis, self-efficacy, and delay gratification than the control group. The experimental group was reported to be significantly lower in depression and impulsivity. Conclusion: The results indicate that NFT using brain cognitive neuroscience approach is effective in enhancing self-regulation response. Therefore, this nursing intervention using brain cognitive neuroscience approach can be applied as an effective self-regulation nursing intervention for adolescents with emotional behavior problems in communities for adaptive life.

This study analyzed the changes in Electroencephalogram(EEG) and Electrocardiogram(ECG) depending on the healing environment in order to find a way to improve the forest healing program based on the healing environment in response to the demand for qualitative improvement of the program since the program is a charged service. This study selected eight sites running forest healing programs at four national healing forests (i.e., Saneum, Cheongtaesan, Daegwanryeng, and Jangseong) - two routes per national healing forest - considering forest environments. This study chose NUMBER standard sampling plots ($20{\times}20m$) and measured three atmospheric environment items, seven physical environment items, two soil environment items, and eight vegetation environment items including forest sound and anion at each plot to evaluate physiological changes in it. EEG and ECG, which have been widely used in forest healing evaluation, were utilized as criteria. Seventy three subjects were selected with taking the age, drug, caffeine, smoking, and the time of last meal into consideration. As a result, EEG changes were correlated with three atmospheric environment items, six physical environment items, one soil environment item, and two vegetation environment items. ECG changes were significantly correlated with two atmospheric environment items, six physical environment items, two soil environment items, and two vegetation environment items (p<.05). It is expected that 11 environmental factors such as temperature, density, and altitude affecting EEG (e.g., alpha balance and gamma balance) and ECG (e.g., HRV mean) could be used as effective tools in developing more differentiated programs for improving healing effects.

Due to COVID-19, the non-face-to-face era has arrived, and telemedicine has become a demand of the times in the medical community. Accordingly, this study aims to present a way to supplement Korea's telemedicine policy by comparing and analyzing domestic telemedicine policy and China's telemedicine policy, and analyzing the success factors of Chinese telemedicine. Domestic and foreign literature was explored to compare and analyze telemedicine policy cases of Korean, Chinese. Domestic and foreign national legal databases and web DBs were used, and literature were restricted between 2009 and 2022. Prior to COVID-19, the scope of telemedicine was very narrow in Korea, and only some pilot projects were operated. After COVID-19, the scope of telemedicine temporarily expanded, but no specific policies or systems were prepared. On the other hand, in the case of China, related policy institutional discussions on telemedicine have been actively conducted since the past, and accordingly, specific scope of application and related management norms and systems have been prepared. For the development of telemedicine in Korea, it is necessary to supplement the definition of telemedicine, ensure the accuracy and safety of non-face-to-face care through telemedicine, and solve the concentration phenomenon of large hospitals through limited conditions for hospital-level medical institutions.
