진영식,윤혜현 동아시아식생활학회 2022 동아시아식생활학회지 Vol.32 No.4

This study was conducted to investigate the quality characteristics of campagne made using different concentrations of the Kimchi sour starter 0% (CON), 10% (KS10), 20% (KS20), 30% (KS30), 40% (KS40) and 50% (KS50). With increasing amounts of the Kimchi sour starter, the pH value of campagne decreased significantly, whereas the moisture content showed a significant increase. The fermentation rates obtained in the CON and KS30 samples were higher than in other samples. The Hunter —a-value (greenness) and b-value (yellowness) of the crumb decreased significantly with increasing amounts of the Kimchi sour starter. Texture profile analysis revealed significantly increased values for hardness, gumminess and chewiness and decreasing cohesiveness and springiness, with increasing Kimchi sour starter. Sensory acceptance showed that the CON and KS10 samples had the highest score for appearance, while KS20 and KS30 showed the highest flavor scores.

저자들은 인제대학 부속 서울 백병원에 입원 및 외래치료를 받은 우울증환자 25명을 대상으로 갑상선 기능을 검사비교하여 다음과 같은 결과를 얻을수 있었다. 1) 우울증 환자군에서 T₃,T₄의 값이 정상대조군에 비해 현저히 낮았다. (p<0.01) 2) 우울증 환자군에서 T.S.H. 의 값은 정상대조군에 비해 큰 차이가 없었다. 3) 주요정동장애 (Major Affective Disorder)의 우울상태 (Depressed State)와 감정부전장애 (Dysthymic Disorder)의 환자들을 정상대조군과 비교하여 주요정동장애에서는 T₃,T₄, T.S.H. 의 값이 현저하게 차이가 있었으며 (p<0.01), 감정부전장애에서는 별 차이가 없었다. 4) 주요정동장애의 우울상태인 환자군에서 감정부전장애 환자군과 비교하여 T₃,T₄, T.S.H. 의 값이 현저하게 차이가 있었다. (T₃: p<0.05, T₄, T.S.H: p<0.01) Authors studied the relationship between the depression and the thyroid function by measuring the serum T₃,T₄and TSH levels with the method of radioimmunoassay. Subjects were consisted of 25 patients (14 depressive states in major affective disordeer, 11 dysthymic disorder) who were treated at the department of Neuropsychiatry, Seoul Paik Hospital from Oct. 1983 to July 1984, and the controls were consisted of 25 healthy medical personnels of the same hospital. The results were as following; 1. The serum of T₃and T₄of the depressed patients were significantly lower than those of the control group. (p<0.01) 2. The serum level of TSH of the depressed patients was not different from that of control group. 3. The serum levels of T₃,T₄and TSH of the depressed states in major affective disorder were significantly lower than those of control group (p<0.01) 4. Compared with each subtype of the depression, the serum levels of T₃,T₄and TSH of the depressed states in major affective disorder were significantly lower than those of the dysthymic disorder group. (T₃: p<0.05, T₄, TSH: p<0.01)

In this paper, analyzes the characteristics of self-weight consolidation on the dredged clay according to the fines content and falling height. Research was performed with the dredged clay sampled by Sae-mangeum field site. Classification of fines content was performed by sieve analysis test. After adjusting the fine content, self-weight consolidation tests were carried out focussing on the variation of fines content and falling heights. From the test results of the self-weight consolidation test, samples with high fines content had reached sedimentation completion more later than ones with less fine content samples. In other words, the start of self-weight consolidation was slowing down with increasing of fines content. Also, from the test results of calculating the coefficient of sedimentation consolidation, the coefficient value were increased with the fines content increases. In addition, the change of sedimentation ratio and volume ratio showed more higher changed value as the fine content increases. Thus, it is important to consider the fines content when estimate the settlement time of dredged soil in field dredge work.

최근 들어 연약지반상에 구조물을 건설하는 경우가 증가하고 있으며, 사회기반 시설의 유지관리 및 건설 비용의 절감을 위해 사전압밀공법 및 연직배수공법과 같은 기존의 방법을 이용하여 지반 개량이 행해지고 있다. 이와 같이 연약점성토 지반상에 다양한 개량공법이 적용 될 때, 점성토의 낮은 투수계수로 인한 장기간에 걸친 압밀침하가 중요하게 된다. 압밀침하와 관련된 기존 연구결과에 따르면, 기존의 표준압밀시험의 재하기간은 압밀정수 산정에 최소한 10일 이상의 시간을 요하게 된다. 따라서 이 연구에서는 서남해안의 대표적인 연약지반으로 구성된 광양만 재성형 해성점토를 이용하여 표준압밀시험과, 일정변형률 압밀시험의 변형률 속도를 변화시킨 실험을 수행하였다. 실내시험결과를 통해 등변형률 속도에 따른 압축특성, 변형률-유효응력관계, 재하속도에 따른 간극수압 변화특성, 압밀정수와 등변형률 속도의 관계를 비교/분석하였다. Recently, the case to construct the structure on the soft clayey ground has increased and in order to the reduction of the cost of construction and maintenance on the social infrastructure facilities we have been trying to improve the soft clayey ground using the existing methods such as the pre-loading method and the vertical drain method. Like this, when various ground improvement methods are applied on the soft clayey ground, a long-term consolidation settlement will be key issue due to low permeability coefficient of cohesive soil. According to existing research results that relate to the consolidation settlement, the loading periods for existing the standard consolidation test (Oedometer test) to obtain the consolidation parameters are needed for minimum ten days or more. Therefore, in this study, the standard consolidation test (24 hours step-loading) and constant strain rate consolidation test changed by strain rate was performed using the remolded marine clay on Gwangyang bay composed of a soft clayey ground of the south-west coast. From the laboratory test results, the characteristics of compression, strain-effective stress relations by constant strain rate and the variation characteristic of the pore water pressure by different of loading speed and the relation between consolidation parameters and constant strain rate are compared and analyzed.

목 적: 공격성은 정신분열병 환자에게 나타나는 심각한 문제 중 하나이다. 공격성의 가장 극단적 형태인 살인 행동을 보인 정신분열병 환자들이 경험하는 주관적인 정신 증상 및 심리 상태의 특성을 알아보고자 본 연구를 시행하였다. 방 법: 살인 행동이 있었던 정신분열병 입원 환자(n=64)를 연구대상으로 하였고 살인 행동은 없었으며 실험군과 나이, 교육 연한, 항정신병 약물 용량을 짝짓기하여 선정한 정신분열병 입원 환자를 대조군(n=75)으로 선정하여 두 군간의 주관적 정신 증상 및 심리상태를 비교 연구하였다. 주관적 상태는 Minnesota Multiphasic Personality Inventory(MMPI)와 Symptom checklist-90-R(SCL-90-R)로 평가하였다. 살인 행동 환자군은 살인 행동 후 정신감정 시점에 검사된 MMPI와 SCL-90-R결과를 얻었다. 결 과: 살인 행동을 보인 환자군은 대조군에 비하여 MMPI와 SCL-90-R검사 모두에서 전반적으로 더 높은 점수를 받았다. MMPI 검사에서 우울증, 히스테리, 반사회성, 편집증, 내향성 척도가 살인 행동군에서 대조군에 비해 유의하게 높았다. SCL-90-R 검사에 서는 강박증, 대인관계 예민성, 불안, 편집증, 정신증 항목에서 살인 행동군에서 통계적으로 유의하게 높은 점수를 보였다. 결 론: 살인 행동을 보인 정신분열병 환자군은 주관적으로 사회적 상황에서 정서적으로 불안정하여 피해의식을 쉽게 느끼고 분노와 정감 조절이 어려울 때 인지적 왜곡에 부합하여 공격적 행동이 유발될 가능성이 있다. Objectives:Violence is a serious problem in some patients with schizophrenia. Homicide is one of the most extreme aggressive behavior. The purpose of this study was to investigate the characteristics of subjective symptomatology and psychological state of schizophrenia with homicidal behavior. Methods:Subjects were schizophrenia patients hospitalized in a mental hospital due to their homicidal behavior (n=64, group 1). Control subjects were schizophrenia patients without homicide also hospitalized in another mental hospital(n=75, group 2). Subjects were matched by age, years of education and dosage of antipsychotics. Minnesota Multiphasic Personality Inventory(MMPI) and Symptom checklist-90-R(SCL-90-R) were used to evaluate the subjective symptomatology. In group 1, the results of MMPI and SCL-90-R had been acquired following the incident that led to hospitalization. Results:Schizophrenia patients with homicide showed overall elevated MMPI clinical scales and SCL-90-R scales. The group with homicidal behavior had significantly higher scores than patients without homicidal behavior on the subscales of depression, hysteria, psychopathic deviance, paranoid, social introversion as assessed by the MMPI. They also had significantly higher scores on the subscales of obsessive-compulsive, interpersonal sensitivity, anxiety, paranoid ideation, psychoticism as assessed by the SCL-90-R. Conclusion:Schizophrenia patients with homicidal behavior did present different clinical subjective pictures : unstable emotion, more paranoid tendency, difficulty with control of anger, more perceptual disturbance. Under those subjective states they had a risk of violent behavior.
