Objective : This empirical research is performed to recognize diagnostic concept, pattern identification, and clinical features of Hwa-byung. In other words, the aims of this research are to examine the differences of the diagnosis between Hwa-Byung and the other psychiatric disorders, and to find out pattern identification, and clinical characteristics of Hwa-Byung for prescriptions of this syndrome. Method : In the experiment, there were participated 30 patients who were met for our criterions according to HBDIS (Hwa-Byung Diagnostic interview Schedule). These patients were diagnosed as Axis1 according to criterions of DSM-IV with administering SCID-I. OMS-prime was utilized for finding out pattern identification of oriental medicine. Symptom Check List-90-Revision(SCL-90-R), Hemilton rating Scale for Depression(HRSD), Heart Rate Variability(HRV), and Digital Infrared Thermographic imaging(D.I.T.I.) were also utilized to discover clinical characteristics of Hwa-Byung Patients. Results : 1. Regarding Sex-ratio, male subjects were 3(10%), and female subjects are 27(90%). The age of subjects ranged from 22 year old to 75 $(51.87{\pm}11.04;\:Mean{\pm}SD)$ 2. In the results of diagnosis on the basis of DSM-IV, the 17(56.67%) patients were MOD (Major Depressive Disorder), the 5(16.67%) patients were USD (Undifferentiated Somatoform Disorder), the 4(13.33%) patients were Dysthymic Disorder, the 3(10%) patients were GAD (Generalized Anxiety Disorder), and the 1(3.33%) was Panic Disorder. Two of the patients who diagnosed as MOD were diagnosed as Panic Disorder too, and one of them was diagnosed as Pain Disorder too. 3. Regarding pattern identification, Hwa-Byung is positively correlated to deficiency of Heart(心). and then to stagnancy of Liver-Gall bladder. Hwa-Byung is correlated deficiency symptom-complex rather than excessiveness symptom-complex. That is also correlated positively to Pathological heat and fire. 4. In SCL90-R, the mean of PSDI was $(75.3{\pm}10.7;\:Mean{\pm}SD)$. The each mean of the other 11 factors was distributed between50-70. 5. The mean of HRSD was $(17.9{\pm}5.6;\:Mean{\pm}SD)$ in the entire subject's group. Then the group of MDD was $20.9{\pm}4.4$ and the group of USD was $12.0{\pm}4.8$ 6. In the results of HRV. the mean of TP is $972.4{\pm}1174(Mean{\pm}SD)$, this is lower than normal range 1000-200. The other factors were within normal range. Then, there were no significant differences between them (p<0.05). 7. The temperatures of each acupoint have significant differences between HNl(印堂) and PC6(內關), between CV17(顫中) and PC6(內關), between HN1(印堂) and CV8(神闕), between CV17(顫中) and CV8(神闕) in comparison with the average of body temperature in the use of D.I.T.I. (p<0.01) 8. In the analysis of correlation between SCL-90-R, HRSD, HRV. and D.I.T.I. there were no significant results. According to results that the correlation was analyzed with only the MDD group as subjects, there was negative correlation between RMSSD of HRV and HRSD, between LF of HRV and PDSIof SCL-90-R, and between LF/HF of HRV and ANX, PSY, and PDSI of SCL-90-R. Conclusion : In the observation of clinical features of 30 cases of Hwa-Byung patients by using diverse structured tests, there could make diverse diagnosis as depressive disorder, anxiety disorder, and Somatoform Disorder. Particularly. MDD was highly distributed. Considering oriental medicine's pattern identification of Hwa-Byung, this syndrome is related strongly to Heart, and there were demonstrated deficiency symptom-complex, and Pathological heat and fire. One of the limits of this study is lack of control subject's group, therefore, in the future study, it requires reexamination through a comparative research with these data to complete this study.

This study was conducted to determine grazing intensity of growing Korean native goats (Capra hircus coreanae) on mountainous pasture. It was carried out to obtain basic information for improvement of mountainous pasture management and establishing feeding system of Korean native goats. Castrated, male goats (n=10) with average initial body weight (BW) of $23.33{\pm}2.15kg$ and an average age of 4 months were used in this study. Grazing goats were supplemented by concentrates with 1.0% of BW. The crude protein content of forage was the highest in October ($22.71{\pm}0.25%$) and there were significantly differences (p<0.05) in monthly comparison. The forage productivity of pasture was the highest from May to June ($1718.7{\pm}207.5{\sim}1672.0{\pm}422.8kg/ha$ but it was decreased in July ($1356.0{\pm}103.8kg/ha$) because of drought and summer depression. Average daily gains (ADG) of goats were the highest in June ($99.5{\pm}6.4d/g$). Grazing intensity was calculated by forage productivity and dry matter intake (DMI) and was the highest in May (65 head/ha). As shown in the results of this research, grazing intensity was suggested to average 39 head/ha from May to October. It is desirable that adequate grazing intensity was maintained by adjusting supplemental feed.

This study adopts an ecological perspective to empirically navigate the issues surrounding the impact of parental abuse on the emotional development of adolescents. The data is used from the Korean Children and Youth Panel Survey 2011 (KCYPS 2011), which was conducted by the National Youth Policy Institute (n=2,270). Path models were constructed in which adolescents' environmental mediators (i.e., the relationship with parents, friends, and teachers; and school life) control their negative emotions (i.e., aggressiveness, negative physical symptoms, social weakness and depression); in turn to compare the difference between two groups based on parental abuse by using Structural Equation Modeling (SEM). As with the non-abused group (n=1,644), all the environmental mediators remained significant to control their negative emotion; whereas, the abused group (n=626) showed no significant pathway from their relationship with teachers and school life to negative emotion. This indicates that the abused group have limited number of the mediators to control their negative emotion than those of the non-abused group. For the non-abused group, the mediator with the highest total effect to control their negative emotion was the relationship with their friends; on the other hand, the abused group's mediator that showed the highest total effect to control their negative emotion was the relationship with their parents. Although the relationship with teachers remained significant as a mediator to affect school life for the both groups, teachers were not significant to control the negative emotion of the abused group. These findings suggest that the negative relationship with teachers in the abused group is a factor to threat the school adaptation of adolescents, which also leads to problems that are related to the emotional development of adolescents.

The aim of this study is to know how the rat submandibular gland changes under various emotional stress condition, using molecular biological methods. Restraint and chronic unpredictable mild stress (CUMS) experiment is conducted on fifty one 7-week old Sprague-Dawley rats (restraint stress experiment: 21, CUMS: 30). The rats were sacrificed, the submandibular glands were excised immediately at certain time, and examined by the use of immunohistochemistry and western blotting. In CUMS experiment, sucrose preference test, water intake change, weight change were implemented at 1 week interval for the experimental period The results are as follows: 1. The number of clusterin-secreting cells of restraint stress group compared to control group showed significantly decreasing tendency in all experimental groups except for the 1st hour group (p<0.001 in the 9th, 24th, 72nd, 120th, and 168th hour group). 2. The number of clusterin-secreting cells of CUMS group compared to control group showed significantly increasing tendency in the 2nd week group (p<0.01), and significantly decreasing tendency in the 4th and 5th week group (p<0.001). 3. Sucrose preference test in CUMS experiment showed significant difference between the 5th week experimental group and control group (p<0.01). 4. Weight change in CUMS experiment showed significant difference between the 5th week experimental group and control group (p<0.01), but water intake change didn't show significant difference compared to control group. 5. In western blot analysis, clusterin expression was decreased on a gradual basis in due time compared to the control group in the restraint stress group. As for CUMS group (chronic unpredictable mild stress group), it was increased till the 2nd week and decreased till the 5th week after that, which is similar to immunohistochemical analysis result and the decreasing tendency of sucrose preference and weigh changes. Through the test, it was proved that expression of clusterin in saliva glands decreases after receiving either acute or chronic stress, indicating relation with depression caused by chronic stress. Unlike other data, however, apoptotic tendency was hardly found in tissues. Diverse possibilities could be suggested on that: first, the stress was not enough to expedite apoptosis; second, apoptosis-related protein was already being secreted though not detected with microscope; third, clusterin, a major secretion molecule of saliva, decreased with saliva's malfunction due to stress. In the respect, it will be necessary to examine proteins expressed in case of cell death or other heat-shock proteins at the same time, in order to see whether any cellular change or death is caused by decreasing clusterin under high stress, and whether the original state is restored as time goes by under mild stress, through longer-term tests using even higher acute stress.

Purpose: This study was conducted to investigate the prognostic factors of postpsychotic depressive symptoms in patients with schizophrenia. Materials and Methods: Eighty patients were selected based on the diagnostic criteria from the DSM-IV, PANSS and ESRS. For all patients information was collected on demographic and clinical characteristics. The subjective depressive symptoms and the objective depressive symptoms, as well as patients insight regarding psychosis were evaluated. The subjective depressive symptoms were evaluated by BDI and ZDS; the objective depressive symptoms were evaluated by HDRS and CDSS, and patient insight into the psychosis was evaluated by KISP. Results: The comparisons using demographic and clinical characteristics showed that HDRS and CDSS had significant difference with regard to gender and suicide attempts; the BDI was associated with difference in education level and age of onset. The patients with scores above cuff-off score for each scale were 20(25.0%) for the BDI, 16(20.0%) for the ZDS, 18(22.5%) for the CDSS and 6(7.5%) for the HDRS. The results of the stepwise multiple regression analysis showed that the scores for the KISP, education levels, gender and suicide attempts were the main prognostic factors in patients with the psychotic depressive disorder of schizophrenia. Conclusion: The main prognostic factors in psychotic depressive disorder of schizophrenia included: insight into psychosis, suicidal attempts. Insight into the psychosis was the most reliable prognostic factor but this characteristic had a negative relationship to the with depressive symptoms.

This field experiment was undertaken to assess the effects of three levels of inclination ($10^{\circ}$, $20^{\circ}$ and $30^{\circ}$) and four rates of $N-P_2O_5-K_2O$ (0-0-0, 14-10-10, 28-25-25, and 42-40-40 kg/10a) on the hilly pasture concerning to establishment, forage yield and quality, and botanical composition in the mixed grass-clover sward set up on a new reclaimed woodland by an oversowing method. This part was concerned with the concentration and mutual balance of mineral nutrients in relation to grass tetany hazard. The results obtained were summarized as follows: 1. Concentration of exchangeable Mg, relative proportions of Mg to CEC, K, and Ca in soil were considerably below the critical level for good forage growth and prevention of grass tetany. These properties were rather worsened by increasing the inclination grade and the NPK rate. 2. Compared with the critical level for the likelihood of tetany (Mg < 0.2%, K > 2.5%, and K/(Ca+Mg) equivalent ratio > 2.2 in forages in DM basis), mean concentration of Mg in mixed forages turned out to range from 0.09 to 0.14%. 2.6% of K concentration and 2.5 of K/(Ca+Mg) equivalent ratio were shown to be at a normal NPK rate. The likelihood of grass tetany was generally enhanced by increasing the inclination grade and the NPK rate. 3. The increasing of the inclination grade and NPK rate rather aggravated the low Mg concentration and unbalanced mutual ratios of mineral nutrients, from which resulted the grass tetany hazard and the depression of forage growth. To prevent these two resulted factors, Mg fertilization on grassland and/or extra Mg supplement to dairy cattle needed to be carried out. 4. The Ca/P ratios in the mixed forages ranging from 1.0 to 2.0 were reduced by the increased rate of NPK, whereas the difference due to inclination grade was yet to be recognized.

Objectives : The aim of this study is to evaluate difference of somatic symptoms of anxiety disorder and major depressive disorder and domainal association with suicidal idealization, plan, and attempts. Methods : A total of 359 adults diagnosed with major depressive disorder and anxiety disorder of last one year participated. Participants interviewed with certain sections of Korean version of Composite International Diagnostic interview of CIDI. Sections of interests includes questionnaires regarding somatic symptoms and suicidal idea, plan and attempts of last one year. Results : Chest pain shows more prevalence in major depressive disorder. Symptoms of Headache and loose stool are more prevalent in anxiety disorder. Difficulty in equilibrium and fainting spells are more common somatic complaints of co-diagnosis states of anxiety disorder and major depressive disorder. Comparing 3 domains of pain symptoms, gastrointestinal symptoms and pseudo-neurological symptoms, pain symptom domains, gastrointestinal symptoms domain shows significant statistic difference between diagnosis. Average somatic symptom numbers of each symptom domains increase through suicidal idealization, plan and attempt, accordingly. Conclusions : Our finding shows some of somatic symptoms are more prevalent at certain diagnosis. Since increasing numbers of somatic complaints of each symptom domains goes with the suicidal idealization to suicidal attempts, proper psychiatric evaluation and consultations are crucial for patients with numerous somatic complaints in non-psychiatric clinical settings.

Objectives : The purpose of this study was to investigate the characteristics of psychosocial factors related to functional dyspepsia(FD) and their effects on quality of life(QOL) in firefighters. Methods : This study examined data collected from 1,217 firefighters. We measured psychological symptoms by Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) and World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF). Chi-square test, independent t-test, Pearson's correlation test, logistic regression analysis, and hierarchical regression analysis were used as statistical analysis methods. Results : For the group with FD, the male participants showed significantly higher frequency(p=0.006) compared to the female participants. The group with FD had higher scores for depressive symptoms(p<.001), anxiety (p<.001), and occupational stress(p<.001), and did lower scores for self-esteem(p=.008), quality of life(p<.001) than those without FD. The FD risk was higher in the following KOSS subcategories: job demand(OR 1.94, 95% CI : 1.29-2.93), lack of reward(OR 2.47, 95% CI : 1.61-3.81), and occupational climate(OR 1.51, 95% CI : 1.01-2.24). In the hierarchical regression analysis, QOL was best predicted by depressive symptoms, self-esteem, and occupational stress. Three predictive variables above accounts for 42.0% variance explained of total variance. Conclusions : The psychosocial factors showed significant effects on FD, and predictive variables for QOL were identified based on regression analysis. The results suggest that the psychiatric approach should be accompanied with medical approach in future FD assessment.

According to the result of 2017 youth statistics, the first rank of the death cause of Korean youth is suicide for nine years. The recent study on factors affecting juvenile suicide presents: family factors; character and psychological factors; mental disease factors; suicide-triggering factors; school factors; and protection factors; and so on. What is required to the youth who are vulnerable to the confusion of identity and the adjustment of emotion or impulse is not only drug treatment or mental therapy but also the support of family or society where adolescents are encouraged to be introspective and form their identity in a healthy approach in the diverse humanistic philosophical dimension. This study is going to pay attention to the aesthetic existence of Kierkegaard who provided the foundation of human existential identity centered on three stages of existence. For this purpose, we attempt to search for the philosophical basis for the understanding of juvenile identity centered on the analysis of Kierkegaard's Either / Or Volume I (Entweder - Oder Teil I). Especially, we are going to attempt the understanding of aesthetics of youth through the analysis of three stages of desire (Begierde) suggested in Chapter 2 of this book. Herewith he suggests aesthetic existence through 'desire', and aesthetic existence as the desire again through three stages of 'dreaming ($tr{\ddot{a}}umend$)' desire, 'searching (suchend)' desire, and 'desiring (begehrend)' desire. Based on this analysis of three stages, we plan to graft the roots of sociological factors presented as the cause of youth's suicide onto the analysis of existential philosophy. Through this, we attempt to grope for the diagnostic and healing discourse which Kierkegaard's existential analysis can present in the formation and recognition of youth identity and disclose a factor of the emotion or the disorder of impulse adjustment as well as depression suggested as the main contributing factor of youth's suicide and search for philosophical discourse for the prevention of juvenile suicide.

Among 20th century Western ideologies (Western civilization), existentialism is a spirit of the times to restore humanity as rationality and advanced technology have driven mankind to impoverishment and death, experiencing the First and Second World War, Great Depression, Fascism and the Spanish Civil War. In his literature, $Andr{\acute{e}}$ Malraux records his existential agony of how mankind lives and faces death by questioning the fateful life and death of characters. For Malraux's characters, the absurdity of existence related to the human identity means self-examination. Malraux explores existential consciousness and actions of characters in the presence of a concept known as death relative to terror, revolution, and adventure. Malraux deftly addresses the concept of death in his literary works, and it has being emphasized as a central subject for philosophical speculation. In Les $Conqu{\acute{e}}rants$(1928), La Voie Royale(1930), La Condition Humaine (1933), L'Espoir(1937), Malraux suggested a philosophical thesis of the meaning of life through characters in tragic situations, and sought out the consciousness of being and the existential meaning through how the characters control their fate. Malraux, in such a tragic perspective of the world, portrays humanity, affirmation of life, and characters' consciousness and actions in denying death. The agony of death triggers escapist behavior such as having unpredictable instinctual desires such as gambling or smoking opium, but these are desperate struggles to flee from frustration and related to the question of one's existence. What is always emphasized with respect to Malraux's existentialism is the tragic metaphysics of the inevitable destiny of the human condition eventually leading to the question of how humans ultimately confront death. But as characters unite in times of war, revolution and adventure in the novel, such cooperative actions symbolizes a keen sense of solidarity reflecting a camaraderie that transcends individualism. Fellowship among people who voluntarily gather for the common cause of philanthropy and restoring humanity is possible because of the underlying human greatness to sacrifice for such a noble cause. Therefore, Malraux's camaraderie includes the victory of existentialism in creating a world of humanism.
