Stresses from desolate urban environments cause illnesses and worsen health conditions of urban residents, while natural environments have a positive influence on human. Natural healing programs such as forest therapy and horticultural therapy can be differentiated by the characteristic of activity space. However, previous studies of healing programs have focused on either forest therapy or horticulture therapy and there is a limit to comprehending the effects of adopting and connecting various healing programs. This study compares and analyzes the physiological and psychological effects of forest therapy and horticultural therapy to identify the effects and differences by types of healing programs. The before and after effects of horticultural therapy and forest therapy are measured by experiment and survey for 5 days with 5 subjects in each program. For physiological reaction, blood pressure, pulse, and cortisol levels are measured and the profile of moods states(POMS) is used to measure psychological reaction. Collected data are analyzed with the analysis of variance(ANOVA) and Paired-Sample T-test in SPSS 18.0. The results of this study are as follows: 1) forest therapy and horticultural therapy show positive effects in physiological and physiological aspects, 2) forest therapy is more effective than horticultural therapy in physiological relaxation and stress mitigation, 3) horticultural therapy has a tendency to alleviate depression more effectively than forest therapy. In conclusion, this study contributes to providing fundamental information for the development of healing programs and design guidelines for healing spaces through identifying the characteristics of each healing program.

Recent research has shown that university students experience severe stress and depleted directed attention due to study, social relationships, and economic dependency. Based on the stress reduction theory and the attention restoration theory, this study aims to investigate the effects of natural landscape on university students' stress and cognitive performance through a wide array of measurements including GSR(galvanic skin responsse), IBI(interbeat interval), ZIPERS(Zucherman Inventory of Personal Reactions), and mental arithmetic test. The restorative effects of natural landscape were compared with those of urban landscape. 128 university students participated in the study, and the data of 120 students was analyzed. The results showed that natural landscape was more restorative in relieving psychological stress and in enhancing cognitive performance than urban landscape, which evidenced the restorative effects of natural landscape. Therefore, it could be proposed that natural landscaping of the university campus contributes to students' stress reduction and cognitive enhancement. But such effects were not found in the two physiological measures(both GSR and IBI). Moreover, it was analyzed that urban landscape had a more beneficial effect than natural landscape for IBI, which might resulted from the participants' characteristics and the study landscape. Specifically, the young age span of the participants(average 23.8 years old) and the very natural setting of the university where they were enrolled might lead to the conflicting results in physiological measures. Also, the urban landscape used in the study had a sense of "scope", which is one of the Kaplan and Kaplan's restorative characteristics. Based on this opinion, it was suggested that future study should investigate the impact of the landscape type and contents as well as the participants' characteristics on the restorative effects of natural landscape.

This study examined how 'forest name' or 'information of forest healing effectiveness' influence their perceived environmental restorativeness (PER) and perceived healing effectiveness (PHE). Study area was the 'Forest Healing Road (FHR)' in Mudeungsan National Park. Data were collected from 247 visitors selected by convenient sampling method using questionnaire survey during May-June, 2015. Respondents who read interpretive signs (forest name and information on forest healing effectiveness of FHR were written) installed along the FHR were regarded as placebo group and respondents who didn't read them as control group. The results showed that there were no overall differences on PER and PHE between control and placebo groups. Placebo group, however, rated more positive on 'being away' factor of PER than control group. All four factors (i.e., being away, coherence, fascination, comparability) of PER statistically influenced PHE (p<0.001), and these factors explained 51.1% of PHE. The 'coherence' was the most influential to PHE, followed by 'being away', 'comparability', and 'fascination' in order. Placebo effects on PER were shown in male, in lower age group(age${\leq}54$), or respondents with lower visiting experience to FHR(${\leq}20$ times/year). Placebo effects on PHE were found in male, in small group (${\leq}2$ persons), in respondents who visited 'alone' or 'with relatives/family', or in respondents with lower visiting experience to FHR(${\leq}20$ times/year). Some research and managerial implications were suggested.

Effortful directed attention becomes fatigued if it is demanded by environment. Kaplan and Kaplan's Attention Restoration Theory (ART) proposes that the fatigued directed attention can be restored by a restorative landscape. The four restorative components are being away, fascination, extent, and compatibility. The restorative effect of landscape has been mainly investigated in terms of nature vs. urban dichotomy, although ART acknowledges that various types of landscapes can induce restorative effect. The purpose of this study is to examine whether sense of place of landscape has an influence on the restorative effect, and how the effect relates to the visiting experience. This study was performed in An-Ap-Ji with 200 Korean visitors who participated in the questionnaire survey. Hartig et al.'s PRS (Perceived Restorativeness Scale) was used as the research instrument to measure the restorative quality. The Analysis results are summarized as: 1) PRS was a very reliable measurement for Koreans' assessment of traditional landscape. Especially, the factor analysis produced four restorative components which fully supported ART. 2) The sense of place of landscape was found to have a positive influence on the restorative effect. 3) Landscape beauty was also discovered to be influential in the restoration even though the effect of beauty was lower than that of the sense of place. 4) Among the four restorative components, three components (fascination, escape, compatibility) influenced both visiting satisfaction and revisit intention, where the order of the relevant importance was fascination, escape, and compatibility. Based on the results, it was suggested that PRS should be used in landscape restoration research in Korea in order to re-examine its' reliability. It was also proposed that more research should be directed to investigate the relationship between the sense of place and the restorative effect of landscape.

저수준레이저를 이용하여 창상이나 병소의 치유과정에 대한 효과를 조사하기 위하여 많은 연구가 시행되었다. 연구에 의하면 갈륨비소 레이저광이 생체자극효과를 가진다고 하며, 저수준레이저를 조사하면 단백질과 핵산 (DNA) 합성을 자극하여 치은섬유아세포의 증식을 촉진한다고 보고하였다. 외상병소나 근육병소의 치료에 사용된 레이저치료법에 관한 관심이 점증함에 따라 저수준레이저요법 (LLLI)의 치유효과를 설명하기 위하여 분자생물학적 수준의 연구를 시행하기에 이르렀다. 보고에 의하면 Mutans Streptococcide 는 LLLI를 사용시 증식이 촉진되며, 다른 세균에서도 유사한 증식효과가 나타날 것이라고 주장하였다. 그러므로 LLLI가 피부감염을 야기하는 가장 흔한 원인인 Staphylococcus aureus 도 마찬가지로 증식이 촉진되는 지를 조사해볼 필요가 있으며, 또한 감염과 같이 특정 병적 상태에서의 저수준레이저광의 효과는 아직까지 명확하게 밝혀져 있지 않았다. 그러므로 본 연구의 목적은 첫째, Staphyloc occus aureus 의 증식에 대한 저수준레이저광의 효과를 조사하는 실험이며, 둘째 Staphylococcus aureus 로 가염된 피부창상에 대한 저수준레이저광의 효과를 판정하는데 있다. 34개의 Staphylococcus aureus 배양표본을 사용하여 48시간의 세포주기동안 조사기간과 조사시간, 그리고 레이저 펄스(laser pulse)형에 따라 3가지 실험을 시행하여 증식에 가장 효과적인 상태와 가장 비효과적인 상태의 갈륨비소 반도체 레이저펄스를 결정하였다. 이후 지름 약 6 mm의 개방창상을 44마리 백서의 양측 대퇴부에 형성하여 모든 창상에 S. aureus를 감염시켰다. 모든 표본은 펄스형과 조사방법 (중앙조사법과 주변조사법)에 따르는 실험을 하기 위하여 4가지로 분류하였다. 각 백서의 양측 창상중 하나는 1,3,5,7일 마다 각 실험의 방법에 따라 레이저를 조사하고 실험동물의 다른 창상은 대조군으로서 사용하였다. 모든 창상의 면적은 실험 1,3,5,7 일째에 일정한 거리에서 사진촬영하여 면적계를 이용, 측정한 후 통계적인 의의를 조사하였다. 본 연구의 결과는 저수준레이저는 특정 조건하에서 S. aureus의 증식을 촉진하였다. 그러나 S. aureus에 감염된 창상을 저수준레이저로 조사시 치유가 촉진되었다. 중앙 조사법고 주변조사법에 의한 창상치유효과는 통계적인 의의가 보이지 않았다. 따라서 결론적으로 S. aureus 에 감염된 창상에 직접 또는 간접적이든 pulse의 종류에 관계없이 조사하는 경우 치유효과가 나타나는 것은 정사주위 조직의 LLLI 자극효과가 염증의 확산을 억제한다고 말할수 있다.

The paper presents experimental results of self-healing effects of OPC-GGBFS paste with cracked and uncracked specimens. The self-healing of cracked specimens is processes of crack closing with re-hydration of unhydrated in crack surface. The OPC paste with GGBFS replacement ratios of 0%, 10%, 20% and 30% were prepared having a constant water-binder ratios of 0.5. The OPC-GGBFS paste specimens immersed in tap-water and sea-water. The temperature of tap and sea-water was $5^{\circ}C$, $15^{\circ}C$ and $25^{\circ}C$. The cracked specimens after deterioration were immersed for 60 days. The relationship between self-healing effect and age-effect was calculate based upon the experimental results. The self-healing effect was measured in ultrasonic pulse velocity (UPV) before and after loading. When the relative change rate of UPV is increases with the increase in GGBFS replacement ratios. Moreover, the self-healing effect is increased with the temperature of tap-water is increase. But the cracked specimens immersed in sea-water was unclear effects of different temperature. Furemore, most of the healing for OPC-GGBFS specimens immersed in tap-water and sea-water occurred during the first 30 days. The self-healing effect until 30 days is higher than that the age-effect. After 30 days, self-effect and age-effect was largely decreases. SEM/EDS analysis of crack on the surface of the specimens in tap-water were covered with aragonite, and sea-water were covered with brucite.

This study analyzed the healing effect of the design elements of healing environment from the perspective of environmental stress, which is one of the contents of environmental psychology. By examining the objective healing effects of the design elements of the healing environment, this study attempted to prepare a theoretical basis for contributing to the construction of a systematic and systematic healing environment. This study consists of three phases. Firstly, three environmental stress theories (Attention Recovery Theory, Evolutionary Psychology, and Environmental Stress Model) were examined to review the academic basis of which the theoretical concept of the healing environment has been derived and developed. Second, we analyzed 16 previous research on the design elements of healing environment and used them as an analysis framework of this study. Thirdly, 11 foreign studies that proved the healing effects of healing environment design elements through objective research methods were considered and analyzed as an analysis framework, and the basis for applying design elements in constructing healing environment was prepared. The research results are as follows. First, the concept of healing environment was developed from Lazarus's psychological stress theory and Ulrich's theory of evolutionary psychology, suggesting that it can be used as one of the noninvasive healing tools that affect stress reduction. Second, the healing environment design elements could be divided into 15 factors and categorized as physical environment, psychological environment, and social environment, and it was found that most of them were mentioned and studied in the previous research in order of nature-friendly, aesthetic, and openness. Third, most of the previous research on the healing effects of the design elements of the healing environment were related to natural affinity and aesthetics, and it was found that the visual elements of the healing environment could affect the actual stress reduction.
