Background: A validation study is needed to make domestic applications of German Kneipp therapy. Purpose: The study aims to test the effect of a Kneipp therapeutic program in a domestic forest environment on the autonomic nervous system. Methods: The program was made considering the 4 key elements ('exercise', 'regulative therapy', 'nutrition', and 'phytotherapy') of the Kneipp therapy. Total 3 sessions (once a week for 5 hours in each session) were performed to 40 domestic adults divided into four groups (10 in each group). HRV was measured on the subjects before and after the intervention, and its 6 characteristic parameters (TP, VLF, LF, HF, LF/HF, CSI: Cumulative Stress Index) were compared for statistical analysis. Results: For 33 subjects excluding 7 who were disturbed by interrupt factors during measurements, significant improvements after the intervention, were observed in TP(8.64%, p < ..001), VLF(6.96%, p < .05), LF(15.86%, p < .001), HF(8.46%, p < .01), LF/HF(5.77%, p < .05) and CSI(-16.06%, p < ..001). Conclusions: The Kneipp therapy performed in the forest environment was shown to activate the autonomic nervous system and in particular the sympathetic and parasympatheric nervous to promote heart activity, and was also shown to most significantly reduce cumulative stress. The present observations would be the first preliminary evidence that the Kneipp therapeutic interventation in a domestic forest environment results in positive responses of the autonomic nervous system including stress relief.

The purpose of this study is to understand in depth the experiences regarding the healing of stress that takes place in the process of the job performance of fire fighting officers. For this, by having seven incumbent fire fighting officers as the subjects of the research, the individual in-depth interviews had been conducted. As a result of analyzing their experiences based on the phenomenological research method of Colaizzi, the 17 topic bundles, 5 subcategories, and 3 categories were derived. Regarding the results of the research, firstly, it appeared that the stress resulting from the job performance in the diverse processes of solving the petitions experienced as the obsessive anxiety, feeling of depression and sleep disorder, etc. Secondly, it had appeared that fire fighting officers show the strong feeling of pride and sense of calling regarding the job performance, but their dread regarding the life after the retirement was high. Thirdly, it appeared that such stress were offset and healed through the positive experiences, including the professional vocation, companionship and support by the family, etc. Because the high job stress gets developed into the continuous and complex physical problems and the emotional and psychological problems, it shows that there is a limitation to the healing with only the professional calling, companionship and support by the family. As such, for the healing of stress that takes place in the job performance by fire fighting officers and not just for the environmental improvements that are related with the job, but for the psychological and emotional support, this research arrived at the point of the suggestion that the operations of the complex and systematized supporting programs, including the strengthening of vocation and companionship, emotional support by the family etc., must be carried out.

본 연구는 사회적 관광과 복지관광에 대한 선행연구 검토를 통해 해양휴양복지에 대한 개념을 정립하는 한편 국외 해양휴양복지사례 및 국내 문화 관광복지 정책 및 산림휴양복지 정책, 국내 해양휴양관광 실태 분석을 통해 국내 해양휴양복지 발전 여건을 파악했다. 우리나라 국민들은 해양을 통한 휴식 및 휴양에 대한 수요가 높으며 만족도 또한 높아 향후 해양휴양복지 서비스에 대한 수요 또한 높을 것으로 전망된다. 다만 해양관광 관련 정책 중 복지와 관련된 사항은 어업인, 연안 어촌에 집중해 추진되어 왔으며, 전 국민이 해양을 통해 보편적으로 누릴 수 있는 복지 서비스 측면에서는 다루어지지 않았다. 향후 우리나라 해양휴양복지 정책은 해양치유 및 해양휴양 자원을 발굴하고 관련 프로그램을 개발하는 한편, 해양치유를 통한 해양휴양복지 서비스를 누릴 수 있는 공간을 조성하고, 전국민이 해양휴양복지 혜택을 받을 수 있는 법제도적인 기반을 마련해야 한다.

This study aims to consider spiritual therapeutic landscapes thought the case of catholic sacred places in Korea. The catholic sacred places, which have been a series of persecution, are distributed in 300 all over the country and can be divided into a formational type, a selective type, and a participatory type. In the formational type, the catholic sculptures are scattered here and there; but it seems that there are limits somewhat to feel the emotional stability and the experience of caring by God. Because the formational type is deserted or is built up in unnoticeable urban areas. The religious factors, for example, museums, special pray, Station of the Cross, Rosary way, statues of the Virgin Mary, catholic sculptures, etc. in the selective type are placed in the corners of the catholic sacred places to provide the opportunity of holy experience to pilgrims. But the level and the intensity of healing depends on the matter as to how much pilgrims experience religious factors voluntarily. Lastly, the participatory type means the experience of various religious factors following scheduled programs. The experience is for the group of pilgrims, not a person; and the human relationship via the religious experience spiritualizes the network of interest towards other participants. Furthermore, the spiritualized open mind towards other people becomes the power that can arrive at the emotional stability, the relief of stress, and the in-depth and authentic healing. Ultimately, the spiritual healing through religious factors is to realize human finitude and dedicate one's own self to God; in addition, the spiritual therapeutic landscapes are the place that can carry out such a spiritual ritual without any restraint.

This study investigated the self-healing properties of blast furnace slag cement paste sample with $Na_2SO_4$ as a blast furnace slag activator after conducting the permeability test. Self-healing properties were examined by crack filling ratio and quantification of self-healing products. The degree of self-healing was evaluated by the crack filling ratio, and the crack filling ratio was analyzed by panoramic analysis using BSE-DIP for objectivity. The average crack filling ratio showed a tendency of decreasing from the upper part of the specimen to the lower part as the average of the top part was 18%, the middle part was 7% and the bottom part was 5% on average. The maximum crack filling ratio was 44% and the minimum crack filling ratio was 3%. The residual self-healing product after the permeability test contained a large amount of Ca element and Al element derived from the blast furnace slag, and the Si element was mainly present near the crack surface. The most abundant minerals in self-healing products were about 68% C-A-H. $CaCO_3$ was about 13% and C-A-S-H was about 8%. Three minerals accounted for 90% of self-healing products. C-A-H was mainly present at a part slightly distant from the crack surface and showed an angular or acicular shape. The C-A-S-H was generated on the surface naturally connected to the existing specimen, and the $CaCO_3$ was generally observed on the surface of the specimen or the inside of the crack.

In this paper, to evaluate the effect of SC on the crack self-healing performance and mechanical recovery performance of cement composites, encapsulated intumescent inorganic material-based solid healing materials were prepared. SC was mixed with cement composite materials to evaluate the basic properties, permeability test, and load reload test. SC slightly improved the flow of cement composites, and the compressive strength decreased by about 10 %. Also, the flexural strength decreased by about 30 %. It was found that when SC was mixed with the cement composite material by 5 %, the crack self-healing rate of Plain was improved by about 𝜟10 %. As a result of the load reload test, it was found that the mechanical recovery rate of Plain was improved by about 𝜟20 %. In addition, as a result of analyzing the correlation between the crack self-healing rate and the mechanical recovery rate by the load reload test, it is judged that the healing area of the Plain can be increased due to SC.

In this study, cellulose-based bacterial pellets was used for the self-healing concrete manufacturing. The pellet is composed of complex cultured bacterial spore powder, methyl cellulose, two kinds of PVA nutrients and water, and is extruded through a hydraulic press to have a shape of 2mm in diameter to 3 to 4mm in length. Cellulose pellets expand at neutral pH, release bacteria and nutrients, and do not react in a basic environment, increasing the long-term survival rate of bacteria in cement mortar. In addition, pellet self-healing performance of pellet mortar was significantly higher than that of control mortar. Cellulose-based pellets are a new type of bacterial carrier system that will help develop self-healing concrete in the future by improving and optimizing pellets.

To answer the question whether last clonogenic cell should be eradicated for the tumor to be controlled, radiation tumor control study was performed using microscopic tumors of variable sizes ranging from 101 to 10s tumor cells. $TCD_{50}'s$ estimated from experimental data were 14.8, 27. 1, 42.4, 49.9 and 65.5 Gy for $10^1,\;10^2,\;10^3,\;10^4\;and\;10^4$ tumor cells, respectively. Theoretical calculations, assuming that all the clonogenic cells should be inactivated, were 15.65, 8.50, 40.97, 53.41 and 65.85 Gy. From this well matched data, it can be concluded that all the clonogenic cells should be eradicated for tumor control, at least in this tumor model.

This study evaluated the mechanical properties and crack-healing abilities of zirconia composite ceramics. The six kinds of specimens used were: partially stabilized zirconia (Z) and five zirconia composite (ZS, ZST1, ZST2, ZST3, and ZST5) with SiC and $TiO_2$. There was not a large difference between the Vickers hardness of the six types of zirconia ceramics. The bending strength of the ZS specimen degraded rapidly, but the zirconia specimens with $TiO_2$ (ZST1, ZST2, ZST3, and ZST5) showed improved strength. Therefore, it was determined that the bending strength is affected by the crystallization, which is due to the addition of SiC and $TiO_2$. From the crack-healing conditions having the highest bending strength, monolithic zirconia retained its cracks, while the specimens of four types with SiC healed their cracks.
