장혜숙,김경미,정순진,김재순 인간식물환경학회 2019 인간식물환경학회지 Vol.22 No.1

The purpose of this study is to investigate the effects of the exhibition displays and events of the Agro-healing Experience Hall in the Agricultural Technology Exhibition 2018 on satisfaction and revisit intention of visitors. A survey was conducted on visitors of the Agro-healing Experience Hall and the responses of 274 visitors excluding 26 cases with inappropriate responses were analyzed. For psychological measurement, the Perceived Restorativeness Scale (PRS), Profile of Mood States (POMS), level of plant gardening experience, satisfaction and loyalty were measured. There was a significant difference among age groups in all four factors of the PRS (repose, fascination, coherence, and legibility). In the case of education level, there was a significant difference in the three factors (repose, fascination, and legibility). In addition, average monthly income showed a significant difference among groups in the two factors (fascination and coherence). As a result of analyzing the mood states of visitors for the exhibition events of the Agro-healing Experience Hall, there was a significant difference among age groups only in the case of vigor (p < .05). As a result of analyzing the correlation between the level of plant gardening activities (3 factors) and PRS (4 factors) in the exhibition events of the Agro-healing Experience Hall, plant preference tendency and plant-related event showed a high positive correlation of 0.5 or more with repose of the PRS factors. A multiple regression analysis was conducted to investigate the effects of the level of plant gardening activities, PRS and POMS on the satisfaction and loyalty of visitors. As a result, it was found that in terms of relative explanatory power over independent variables affecting satisfaction and revisit intention, fascination had the greatest effect, followed by vigor, fatigue, and occupation (company employee). The results of this study suggest that exhibition events of the Agro-healing Experience Hall affect repose, fascination or vigor of visitors, and thus can be used positively to increase satisfaction and revisit intention of visitors.

장혜숙,김경미,정순진,김재순 인간식물환경학회 2018 인간식물환경학회지 Vol.21 No.3

This study was conducted to find out the influence of plant cultivating activities program to reduce the stress of parents. Saliva cortisol salivettes system method was taken effect for this study with total 27 of parents who are 39.15±3.5 years old on average and have children attending primary school. The cortisol level was measured once a week, total 10 times, before/after 90 minutes plant cultivating activities program. As the result of this program, the total cortisol decreased after the plant cultivating activities program and there was a statistically significant difference with the total cortisol (t=14.521, p <.01). In addition to this, the final session has the most effect on decreasing the stress compare to other previous sessions. As the result of asking 8 questions on a 7 point Likert scale about preference for plants and plant-related experiences before/after the plant cultivating activities program, the score difference of “The experiences of growing plants still have an influence on my life” was highest between before and after the program at a statistically significant difference. These results imply that the plant cultivation program can boost stress-reducing effects, allow parents being familiar with plants, and provide positive influence on relieving parenting stress. In addition to this, the standardization of physiological changes can be established more easily with the saliva cortisol method as it is less stressful to the subject and a more convenient test, that can be taken anytime and anywhere, compared to the blood cortisol method.

장혜숙,김경미,정순진,김재순 인간식물환경학회 2019 인간식물환경학회지 Vol.22 No.2

This study investigates the color stimuli of two varieties of foliage plants by extracting electroencephalogram, electrocardiogram and physiology activity data from 30 participants in their 50s or older. Changes in the physiological activity of subjects against six color stimuli were examined. The stimulus to real green plants ‘Silver Queen’ was set as the control group, and was compared with other groups including the stimulus to real ‘Angel’ plants and four stimuli to artificial colors (two color images and color schemes of the same green and red plants). Compared to the five groups, the relative theta power spectrum (RT) and the ratio of alpha to high beta (RAHB) increased in the subjects exposed to real green plants. This result demonstrates that the green plant (‘Silver Queen’) increases the stability, relaxation, and internal concentration of subjects in a proper state of awakening. The result of this experiment showed a statistically significant difference in the level of RT when subjects were exposed to the groups of real green and red plants. This finding indicates that the green plant increases internal concentration more than the red plant. RT and the relative low beta power spectrum (RLB) in the groups of natural colors were higher than the groups of artificial colors when subjects focused their mind on the two types of real plants. However, the level of relative mid beta power spectrum (RMB), ratio of SMR to theta (RST), ratio of mid beta to theta (RMT), relative high beta power spectrum (RHB), and spectral edge frequency 95% were higher when subjects were exposed to the photos and colors scheme of plants than when they were exposed to real plants. The subjects experienced more “comfortable” emotions when they were looking at plants with green colors. Overall, it is recommended to use the natural colors of real plants in places where which stability and relaxation are required. On the contrary, the artificial colors of plants such as their photos and color schemes are useful in places where a high level of concentration is required in a short period of time.

The gastrointestinal (GI) tract is one of the commonly affected organs in amyloidosis. However, it is difficult to make a correct diagnosis of GI amyloidosis because of its varied clinical manifestation and nonspecific endoscopic findings. Moreover, GI bleeding as a presenting symptom is rare, but can be serious in some cases. Therefore, missed diagnosis and delayed management in GI amyloidosis may potentially lead to a critical outcome. We report a 51-year-old man with multiple myeloma whose major symptom was massive hematochezia due to GI amyloidosis. In our case, amyloid deposits could be distinctly visualized endoscopically in the stomach and the colon. They were manifested as submucosal hematomas in the small bowel resulting in massive bleeding that was successfully controlled with the aid of intraoperative endoscopy. (Korean J Gastrointest Endosc 2003;26:220-225) 위장관은 유전분증에서 흔하게 침범되는 신체 기관 중 하나이다. 위장관 유전분증의 임상 양상은, 증상이 없거나, 복통, 식욕부진, 설사, 구토, 흡수장애, 천공, 출혈, 가성위장관폐쇄 및 운동 장애 등 매우 다양한 증상으로 발현된다. 이러한 증상 중 특히, 위장관 출혈은 내원 시 증상으로 드물게 나타나지만, 일부에서는 대량 출혈로 발현될 수 있어, 적절한 진단과 치료가 지연될 경우 위험한 결과를 초래할 수 있다. 하지만, 다양한 임상 양상과 더불어 위장관 유전분증에서의 내시경 소견이 비특이적이기 때문에, 이를 조기에 진단하기가 쉽지 않다. 저자들은 소장 대량 출혈로 발현되어 수술중 내시경을 통하여 치료에 도움을 받았던 유전분증 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

장혜숙,김경미,정순진,김재순,유은하 인간식물환경학회 2019 인간식물환경학회지 Vol.22 No.5

This study was conducted to investigate psychological and physiological changes of elderly affected by agro-healing activities. To meet the purpose, we conducted an agro-healing program with 20 elderly participants (average age 77.6±5.84 men and women) and once a week in total seven sessions. The Korean version of the Brief Encounter Psychosocial Instrument (BEPSI-K), Korean version of the Short Form of Geriatric Depression Scale (SGDS-K), participants’ satisfaction with the program, Salivettes system method, and blood pressure were measured to find out the effects of agro-healing activities. BEPSI-K decreased by 5% in the high stress group although it was not statistically significant. The result of program satisfaction showed that 75% of the participants are satisfied with these activities. We investigated how many and what kind of chronic diseases the participants have had before they joined the program. As a result, hypertension was most common(35.6%), followed by hyperlipidemia, diabetes, arthritis, lumbago, osteoporosis, and heart disease. Systolic blood pressure after the activities decreased significantly from 144.75mmHg (stage 1 hypertension), to 132.90mmHg(prehypertension stage). As a result of analyzing the correlations between general matters such as age, education level, average income of the participants, psychological scale and number of diseases, it was found that participants’ satisfaction had a negative correlation with depression. In conclusion, agro-healing is very useful in relieving stress or lowering blood pressure for the elderly whose most common disease is hypertension. Agro-healing activities are proved to have positive uses in reducing the problems of the modern society with severe issues of the aging population.

정보화 사회의 발전으로 각 조직체는 정보시스템 의존도가 매우 높아지고 있다. 이에 따라 정보시스템에 장애가 발생하여 신속하게 대응하지 못하면 조직체의 신뢰에 치명적인 결과를 초래하게 된다. 최근에는 정보시스템의 지나친 업무 의존도 때문에 사이버테러의 주요 공격 목표가 되고 있다. 대학의 정보시스템은 기업의 정보시스템 보다 안전성이 더욱 취약하지만, 정보시스템의 가용성 확보를 위한 정책지원이 거의 없는 실정이다. 본 논문은 대학의 학사정보 서비스를 위해 시스템 장애에 대비한 재난 복구의 이론적인 내용을 고찰하고 학사정보 서비스의 가용성이 확보될 수 있는 PC 기반 학사행정 고가용성 정보시스템 구현에 관하여 연구하였다. Most organizations are more depending on information system in advanced information society. According to this current, unrapid reaction to system failure can cause a fatal effect to a credibility of the organization. An excessively high level of dependence on information system at work makes itself as a primary target of cyber terror. The stability of university's information system is especially weaker than the enterprise's but policy support for securing availability is inadequate. In this paper, we consider the recovery system toward to disorder of university's school affairs information system theoretically and suggest high availability PC based academic administration system.

장혜숙,유은하,김정희,정순진,김재순,류두영 인간식물환경학회 2020 인간식물환경학회지 Vol.23 No.5

Background and objective: This study investigated plant type and color preference and conducted a psychological assessment for gardening activities of firefighters in a high-risk occupational group. Methods: A survey was conducted on 117 firefighters aged 39.01±9.17 in Sunchang in March 2020 to examine their preferences in plant type and color and conduct a psychological assessment of firefighters on gardening activities. Results: For plant experience and awareness, plant-related event showed the highest score, followed by plant preference tendency and plant growing experience. The level of plant gardening activities was higher among older age and higher job position. As a result of examining the quality of life according to the demographic characteristic with WHOQOL-BREF (World Health Organization Quality of Life Assessment Instrument), it was found that the quality of life was higher among the 20s-30s than 50s, firefighter position than fire lieutenant or higher, those with higher average monthly income, and the singles group than married (p < .05). The administration group showed lower scores than the fire suppression group working in the field, showing statistical significance. Most firefighters showed high preference for herbal plants among the 12 types of flowering plants, in the order of Rosmarinus officinalis⟩Lavandula spp.⟩Mentha piperita, Calendula officinalis. Pelargonium spp. was preferred the least out of the flowering plants, Lycopersicon esculentum was preferred the most out of 12 types of vegetable plants, while Angelica acutiloba was preferred the least statistical significance. For the preference of plant colors, yellow was the most preferred color, followed by white, blue, orange, red, and green, showing statistical significance. For the psychological survey responses of emotion words toward 6 plants colors, it was found that ‘bright’ was the emotion felt most strongly by the white, yellow, and orange groups, ‘calm’ and ‘comfortable’ by the green and blue groups, and ‘fancy’ by the red group. Conclusion: The effect of agro-healing programs can be increased by using mostly yellow plants when creating indoor healing gardens at the workplaces of fire officials in a high-risk occupational group, and using herbal plants and Lycopersicon esculentum in the gardens for agro-healing activities.

장혜숙,김경미,정순진,김재순 인간식물환경학회 2018 인간식물환경학회지 Vol.21 No.5

This study was conducted to find out the neurophysiological changes before and after plant cultivation activity in elementary school parents. Twenty seven subjects participated in total 10 sessions (once a week) of plant cultivating activities and for each session one subject attended an individual activity and the others attended a group activity. Electroencephalography(EEG) and electrocardiogram(ECG) of the subject from the individual activity type and three random subjects from the group activity type were measured before and after each session. The measurements of 7 sessions were analyzed and illustrations of brain map was obtained from the average of each electrode. As a result, the alpha and beta waves of all participants after participating in plant cultivating activities were higher than before participating in the activities, which indicates that the activities increase the activity of the brain. Absolute slow alpha wave (ASA), absolute fast alpha wave (AFA), absolute low beta wave (ALB), and absolute mid beta wave (AMB) were increased after participating in plant cultivating activities, which implies that plant cultivating activities were effective in improving physiological conditions, including stability and relaxation, as well as immersion, attention and concentration. There was no statistically significant difference between those who participated in individual activities and those who participated in group activities. However, both individual and group participants showed higher relaxation, stability and concentration rate after the plant cultivating activity. This study suggests that plant cultivating activities are effective in achieving physiological stability and relaxation and improving immersion, attention and concentration in elementary school parents.

실내 관엽식물의 디자인 요소적 분류에 따른 선호도 및 감성 차이

장혜숙,김광진,유은하,정현환 한국인간·식물·환경학회 2016 인간식물환경학회지 Vol.19 No.5

The study was surveyed to 269 respondents for investigating psychological response to indoor foliage plants grouped by four type of design materials. 21 indoor foliage plants grouped as filler, mass, form, and line plant, are shown to each respondent for surveying the preference and emotion by SD (semantic differential) scale. It was statically significant that the filler plant group was the least preferred one between the indoor foliage plant and the preference of line plant group was the highest. In filler plant Scindapsus aureus is significantly favored, in mass plant Aglaonema crispum and Syngonium podophyllum, in form plant Ficus banghalensis in line plant Dracaena fragrans ‘Lemon Lime’, respectively. The green is the most preferred color of leaf and gray is the least one. When investigated on the major emotions felt with four types of indoor foliage plant with SD scale, filler plant felt as ‘Bright’, ‘Light’, ‘Pale’, mass plant ‘Warm’, ‘Sharp’, form plant ‘Simple’, ‘Luxurious’ and line plant ‘Sophisticated’, ‘Luxurious’, ‘Pleasant’, ‘Soft’ and ‘Fancy’, respectively. This result will be valuable when the indoor garden is designed with an indoor foliage plant.
