BACKGROUND: Caused by cultural environment, the fruit skin stain results in serious damages to pear fruit. Particularly susceptible to this damage, 'Niitaka' pear accounts for 82% of pear cultivation in Korea and many farmers growing the pear trees have suffered economic losses due to fruit skin stain. This study investigated the effect of different treatments of 'Niitaka' pear during growing period on the occurrence of fruit skin stain. METHODS AND RESULTS: The treatments in the field included gibberellin (GA) paste, spraying with amino acid tree fertilizer, functional bagging, and coating of the inner paper bag with agents. The relationships between tree vigor, mineral nutrition concentration and fruit skin stain occurrence were also investigated. The fruit skin stain symptoms occurred from young fruit (May 25) until harvest. There was no exposed fruit flesh. The occurrence of fruit skin stain was significantly reduced in normal tree (shoot length 110 cm), as well as using GA paste treatment, and bagging in calcium and lime sulfur coated bags. However, spraying with amino acid tree fertilizer made no difference in comparison to control. In addition, bags in which the inner paper was coated with lime sulfur and soybean oil resulted in chemical injury to the fruit skin caused by bagging. The K concentration of shoot wood and fruit skin were higher than those of the control. Also, there were lower T-N, K concentration of leaf. CONCLUSION: These results suggest that occurrence of fruit skin stain in 'Niitaka' pear fruits during the growing period can be reduced by GA paste and bagging in calcium and lime sulfur coated bags. The symptoms of chemical injury to the fruit skin caused by bagging in lime sulfur and soybean oil coated inner paper were different compared to skin stain occurring in fruit during the growing period.

This work characterizes 'Yeolha', a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar that was released by the Highland Agriculture Research Center, RDA, in 2013. This cultivar originated from a 2008 cross between 'Goha' and 'Elsinyo' and showed excellent ever-bearing characteristics including continuous a flowering habit under long-day and high temperature conditions. It was originally named 'Saebong No. 5' after examining its characteristics and productivity in summer culture from 2010 to 2013. After two regional adaptability tests in 2012, it was selected as an elite cultivar and renamed 'Yeolha'. The general characteristics of 'Yeolha' include a semi-spreading plant type, elliptic leaves, and strong vigor in growth. Its fruit is conical and red. T he s oluble s olids content of 'Yeolha' is 8 .6%, w hich is 0.6% h ig her than t hat of 'Flamenco', b ut f ruit hardness is lower than that of 'Flamenco'. The average fruit weight of 'Yeolha' is about 12.1 g and the marketable yield is $28,133kg{\cdot}ha^{-1}$, which is 117% higher than that of 'Flamenco'. 'Yeolha' is resistant against Fusarium wilt. In addition, 'Yeolha' is suitable for four-season cultivation as a high harvesting cultivar because it shows continuous flowering under long-day and high temperature conditions.

The purpose of this study is to verify the effects of yoga and meditation-focused forest healing programs on profiles of mood states and stress reactions of adults. We tested 17 adults who agreed to participate in the experiments that were conducted for 2 nights and 3 days between September 8 to 10, 2017 in the healing forest located at Hongcheon-gun, Gangwon-do. The test used the simplified version of the inventory for the profile of mood states (K-POMS-B: Korean version of Profile of Mood States-Brief) and the stress response inventory as the measuring tools. For data analysis, we examined the differences in the profile of mood states and stress response of subjects before and after participation in the program through the paired T-tests with the SPSS 24.0 program. The analysis of the impact of the yoga and meditation-focused forest healing program on the profile of mood states of the test subjects showed the statistically significant reduction of the total score of the profile of mood states. Although the vigor among sub-level inventories increased, it was not statistically significant. But the tension, depression, anger, fatigue, and confusion showed a statistically significant reduction. The analysis of the impact of the yoga and meditation-focused forest healing program on the stress response of the test subjects showed a statistically significant reduction. Among sub-level inventories, the tension, somatization, anger, depression, fatigue, and frustration showed a statistically significant reduction, but the aggressiveness did not. It is expected that the results of this study can be utilized in the future as reference data for clarifying the effects of yoga and meditation-focused forest healing programs.

The purpose of this study is to determine the effects of guided imagery activities using music on both mood states and physiological responses of psychiatric inpatients. The experimental group was consisted of 27 psychiatric patients participating in the guided imagery activities using music for 11 minutes. Also, the control group was formed with 27 psychiatric patients with non-musical intervention. Mood states, blood pressure, pulse and skin temperature were checked before and after session. We could see the significant difference in the score of five areas-tension, depression, anger, vigor, fatigue-showed most differences in score. Also, the score of skin temperature of both experimental group and between two groups showed significant differences, too. Therefore, we can conclude that these results were showing that guided imagery activities using music was an effective nursing intervention method for altering mood state of psychiatric patients. Besides, it seemed to have physiological impact to make patients relax tension backed up by change of skin temperature.

Objectives: Recent studies have reported a correlation between obstructive sleep apnea syndrome (OSA) and depression. In attempt to verify the suggestion that eveningness is related to depression, we examined the effect of morningness-eveningness on their depressive mood in patinets with OSA. Methods: The examination was based on the medical records and polysomnography reports of 211 OSA patients. Information was gathered from the patients who filled out the H$\ddot{o}$rne and Ostberg questionnaire (HOQ), profile of mood states-Korean version (K-POMS), and Epworth sleepiness scale (ESS). We compared mean values of K-POMS total, subscales of K-POMS, ESS, and OSA severity variables among the 3 morningness-eveningness groups (morningness, eveningness, and neither groups). Partial correlation analysis was performed between variables and ANCOVA was performed among the 3 groups after adjustment with age and weight. Results: There were significant negative correlations between HOQ and the followings : K-POMS total, POMS-T (tension-anxiety), POMS-D (depression-dejection), POMS-A (anger-hostility), POMS-F (fatigue-inertia), POMS-C (confusion-bewilderment), spontaneous arousal index, average O2 saturation. There were significant positive correlations between HOQ and the followings : POMS-V (vigor-activity), apnea-hypopnea index, respiratory arousal index, snore time. There were significant negative correlations between POMS-D and the followings : HOQ, POMS-V, stage 1 sleep (%), AHI, TAI (total arousal index), oxygen desaturation index, respiratory arousal index, neck circumference, average O2 desaturation, snore time (%). There were significant positive correlations between POMS-D and K-POMS total, POMS-T, POMS-A, POMS-F, POMS-C, sleep latency, stage 2 sleep (%), heart rate, spontaneous arousal index. There were significant differences in K-POMS total, POMS-T, POMS-D, POMS-F, POMS-C, spontaneous arousal index among the three HOQ groups in ANCOVA. Conclusion: The depressive correlates of OSA patients might be affected, not by excessive daytime sleepiness or OSA severity indexes, but by eveningness circadian characteristics. It would be important to take into account the morningness-eveningness tendency when we manage the depressive mood of OSA patients.

Grief that is not acknowledged and worked through may manifest itself in some emotional, mental or physical problem. In recent years much has been learned about coping with grief which the hospice program can utilize to help family members cope with their grief. This study was carried out to determine the helpfulness of the bereavement care of Severance Hospice and to learm more about the grief response of the bereaved. The tools used to collect data were an assessment form used in the bereavement program and the Grief Experience Inventory developed by Sanders and revised and translated 'by the researcher. Data was obtained from bereaved family members(54 for the final grief assessment and 39 for the grief response assessment) receiving bereavement follow-up, from July 1989 to March 1991. Results of the study were as follows: 1. Final Grief Assessment Regarding the resolution of their grief the majority of the bereaved accepted the reality of the death of their family member, while slightly more than three-quarters were able to express their feelings toward their loss. A large majority had returned to activities of daily living well or fairly well and had reinvested their energy in a person other than the deceased. In addition, the physical condition of the majority was good or fairly good. A majority of the bereaved considered the bereavement care to be helpful and almost three-quarters were not considered to be in need of more follow-up. 2. Grief Response Assessment Age was found to have a modoerately positive correlation to appetite disturbance(r=.41, P<.Ol) and loss of vigor(r=.37, P<.Ol) A moderately positive correlation was found between the number of contacts and sleep disturbance(r=2.38, P<.01) Significant differences were found between men and women in regard to guilt(t=2.38, P<.05), social isolation(t=2.44, P<.05) and depersonalization(t=2.07, P<.05) with men having the more intense grief. Significant differences were found in the grief responses of somatization(F=5.82, P<.001), physical symptoms(F=5.87, P<.OOl), appetite disturbance(F=4.40, P<.Ol), despair(3.79, P<,Ol), anger(Fp2.83, P<.05), social isolation(F=3.61, P<.05), guilt(F=3.62, P<.05) and depersonalization (F = 2.58, P <.05). In the first six of these grief responses mothers scored highest, followed by husbands and then wives, In the grief response of guilt, daughters scored highest and on the grief response of depersonalization sons scored highest. Only one grief response, that of sleep disturbance(t= -2.19, P<.05) was found to be statistically significant, with those family members who died at home having the higher scores. Based on the results of this study several suggestions are presented as follows: 1. Since unresolived grief can have a detrimental effect on the bereaved person's mental and phys. ical health it would be good for the nurse, to include questions related to death of family members and the bereaved person's response to the grief, in her nursing assessment. And in the case of unresolved grief the nurse should encourage the person to talk with a trusted friend or counselor and express their fellings of grief. 2. A study to determine the degree of resolution of the grief of those in the bereavement program could be carried out by use of the Grief Experience Inventory early in their bereavement and again 13 months after the death of their family member. 3. A comparison of the grief response of the bereaved in the bereavement program and bereaved not in the program could be carried out using the Grief Experience Inventory. 4. After bereavement programs have been started in other hospice programs it would be good to carry out a joint study of bereavement outcomes of those in the bereavement programs.

This experiment was conducted to evaluate the effect of manure and chemical fertilizer on the forage yield and quality of oat at no-tillage. The experimental design was a randomized complete block design. The three treatments were: chemical fertilizer, manure fertilizer, and chemical and manure mixture. Seedling vigor was higher at chemical fertilizer than manure, but more greener at manure application than chemical fertilizer. Dry matter (DM) content of oat at manure was higher than chemical and mixture fertilizer (p<0.05). There was no difference in DM yield, TDN (total digestible nutrients) yield, and CP (crude protein) yield of oat at no-tillage system, but the fresh yield was significantly higher in chemical fertilizer compared to manure. The CP content for oat was significantly higher in manure than chemical fertilizer. However, no significant effects were observed for NDF (neutral detergent fiber), ADF (acid detergent fiber), TDN and RFV (relative feed value) in different fertilizer application. Based on the results of this study, manure don't affected forage production and quality of no-till oat except CP content because forage oat is used off-season crop.

Myeong(明) Dynasty Period put together clinically various medical theory in Song(宋) Dynasty and Geum-Won(金元) age, organized medical system. They have been developed in theory, which thought of Byeonjeungronchi(辨證論治) more important, and clinical part which included diagnosis, therapy, prevention. In that age reactional medical thought was in fashion because of affect of Ihak(理學), therefore pediatrics have been affected from them. Especially, looking at the symptom of Byeonjeungronchi doctors, Manjeon(萬全), Nobaeksa(魯伯嗣), Wangdaeryun(王大綸), Wanggeungdang(王肯堂), Nuyeong(樓英) had succeed to Jeoneul(錢乙)' the five viscera Byeonjeung(辨證) system. Manjeon advocated Samyuyeosabujokron(三有餘四不足論) about Jangbu(臟腑) and organized the curative principle about Ojangheosil(五臟虛實). Gupyeong(寇平), commented on diagnosis of five viscera and classification of disease of five viscera. Wangdaeryun in the close of Myeong Dynasty Age explained main pulse, pulse of illness in detail according to weakness or strength of five viscera, pathological or physiological features of five viscera and Saenggeuk(生克) relation of Ohaeng(五行) in the book of "Yeongdongryuchwe(嬰童類萃)". Wanggeungdang and Nuyeong had organized system of argument which classified disease as a result of symptom of five viscera. "Yugwajeungchijunseung(幼科證治準繩)" and "Uihakgangmok(醫學綱目) Soabu(小兒部)" had been written by this principle. Nobaeksa had arranged the principle of cure about five viscera and explained method of common use about each organ's disease. Besides, Seolgi(薛己), Janggyeong-ak(張景岳), insisted about Myeongmun(命門) because he thought of Bisin(脾腎) of children and vigor by nature importance. Seolgi had applied and used very well Bojung-ikgitang(補中益氣湯) based on Idongwon(李東垣)'s Biwiseol(脾胃說) and controled and helped spleen and stomach. At the same time, he took a serious view about supplementing children's Sin-gi(腎氣) according to so many spleen and stomach disease was fallen because they couldn't make warm the spirit of Jungju(中州), result of weakening Hwa(火) of Myeongmun. Also Janggyeong-ak took a serious view strengthen of Bisin, so he assorted and used Insam(人蔘) and Buja(附子) to supplement children's weaken energy in kidney Jeonggi(精氣).

This study was conducted to find out optimum cultivars, and growth temperature and stage in peanut sprout for resveratrol production. Morphological characteristic, days to 50% of the final germination percentage($T_{50}$) and early growth vigor were measured in 8 different peanut varieties. In result 'Jopyeong' appeared to be the most appropriate cultivar for peanut production because of its lower contamination rate, lesser lateral root formation, and thicker hypocotyl length. Optimum temperature for growing peanut sprouts was determined 27. Content of resveratrol was examined by high performance liquid chromatography(HPLC) to investigate appropriate growth stage of peanut sprouts for resveratrol production. Resveratrol was higher than $17.0{\mu}g/g$ in peanuts sprouts 9 days after plating. Considering peanut sprout's shapes and content of resveratrol into account, it was most appropriate to harvest in 9-day after germination.

Grafting of fruit-bearing vegetables has been widely used to increase the resistance to soil-borne diseases, to increase the tolerance to low temperature or to soil salinity, to increase the plant vigor, and to extend the duration of economic harvest time. After grafting, it is important to control the environment around grafted seedlings for the robust joining of a scion and rootstock. Usually the shading materials and plastic films are used to keep the high relative humidity and low light intensity in greenhouse or tunnel. It is quite difficult to optimally control the environment for healing and acclimation of grafted seedlings under natural light. So the farmers or growers rely on their experience for the production of grafted seedling with high quality. If artificial light is used as a lighting source for graft-taking of grafted seedlings, the light intensity and photoperiod can be easily controlled. The purpose of this study was to develop a prototype system for the graft-taking enhancement of grafted seedlings using artificial lighting and to investigate the effect of air current speed on the distribution of air temperature and relative humidity in a graft-taking enhancement system. A prototype graft-taking system was consisted by polyurethane panels, air-conditioning unit, system controller and lighting unit. Three band fluorescent lamps (FL20SEX-D/18, Kumho Electric, Inc.) were used as a lighting source. Anemometer (Climomaster 6521, KANOMAX), T-type thermocouples and humidity sensors (CHS-UPS, TDK) were used to measure the air current speed, air temperature and relative humidity in a graft-taking system. In this system, air flow acted as a driving force for the diffusion of heat and water vapor. Air current speed, air temperature and relative humidity controlled by a programmable logic controller (UP750, Yokogawa Electric Co) and an inverter (MOSCON-G3, SAMSUNG) had an even distribution. Distribution of air temperature and relative humidity in a graft-taking enhancement system was fairly affected by air current speed. Air current speed higher than 0.1m/s was required to obtain the even distribution of environmental factors in this system. At low air current speed of 0.1m/s, the evapotranspiration rate of grafted seedlings would be suppressed and thus graft-taking would be enhanced. This system could be used to investigate the effects of air temperature, relative humidity, air current speed and light intensity on the evaportranspiration rate of grafted seedlings.
