연구목적 한국에서 신경성 식욕부진증과 신경성 폭식증을 진단받은 환자 군에서 부모 양육태도의 차이와 각 아형에서 부모 양육태도의 차이가 발병 나이와 섭식장애 증상의 심각도에 미치는 영향을 알아보고자 하였다. 방 법 167명의 섭식장애 환자(신경성 식욕부진증, N=49 ; 신경성 폭식증, N=118)를 대상으로 하였다. 자가보고식 설문지인 부모 양육행동 척도(Parental Behavior Inventory, PBI)를 시행하여 환자가 인식하는 부모님의 양육행동을 측정하였으며, 섭식장애 검사 개정판(The Eating disorder Inventory-2, EDI-2)를 통하여 증상의 심각도를 평가하였다. 결 과 신경성 식욕부진증 환자를 발병 나이에 따라 분류하였을 때, 16세 이후에 발병한 군보다 16세 이전에 조기 발병한 경우 낮은 아버지의 애정, 높은 아버지의 합리적 설명, 낮은 어머니의 과잉간섭을 보고하였다. 섭식장애 증상의 심각도(EDI-2)는 신경성 식욕부진증과 신경성 폭식증에서 어머니의 애정, 합리적 설명과 음의 상관관계를 나타내었다. 단계별 회귀분석을 시행하였을 때, 아버지의 애정, 어머니의 과잉기대와 합리적 설명이 신경성 식욕부진증의 발병 나이에 중요한 영향을 준다는 것을 확인할 수 있었으며, 두 집단에서 모두 어머니의 애정이 높을 수록 EDI-2의 점수가 낮은 것으로 나타났다. 결 론 섭식장애 환자의 평가 및 치료에서 가족의 기능과 인식된 부모의 양육태도가 중요한 역할을 할 수 있겠다. 본 연구 결과는 아버지의 양육방식이 섭식장애 발병나이에 미치는 영향을 밝힘으로써 이제까지 상대적으로 부족하게 평가되었던 아버지 역할의 중요성을 확인하였다. 이뿐 아니라, 섭식장애 증상의 심각도와 어머니의 애정과의 관련성을 확인함으로써 가족 기능에 대한 평가가 치료에 필수적임을 입증하였다. 앞으로 본 연구 결과에 대한 해석 및 적용을 위한 후속 연구들이 필요하겠다. Objectives:To determine the influence of parental behaviors on the onset and severity of eating disorders, this study compared aspects of perceived parental styles, according to eating disorder subtypes and age at onset in Korean women with eating disorders. Methods:One hundred and sixty-seven patients with eating disorders[Anorexia Nervosa (AN), N=49; Bulimia Nervosa(BN), N=118] were recruited for this study. Perceived parent behaviors were assessed with Parental Behavior Inventory(PBI) self-rating scale. The study subjects also completed the Eating Disorder Inventory -2 (EDI-2) to assess the severity of eating disorder symptoms. Results:In anorexia nervosa, early onset group(<16 years) reported low paternal affection and high paternal rational expression, low maternal interference than group with age at onset over 16 years. The severity of eating disorder symptoms was negatively associated with mother affection and rational expression in two subtypes of eating disorder(AN and BN). On stepwise regression analysis, paternal affection and maternal over-protection were associated with age of onset only in AN group and maternal affection was associated with the severity of symptoms in both groups of eating disorder. Conclusions:Considering the role of family function and perceived parental styles could help improve the management of eating disorders. These results emphasize the importance of fathers' role in the eating disorder on the age of onset, a relatively unexplored area of eating disorder research. Also, we investigated the importance of mothers' affection on the severity of symptoms.

This study was conducted to determine the optimum conditions for the treatment of polyamine to promote pollen germination and improve the fruiting rate by overcoming fertilization defects in low-temperature strawberry cultivation. The optimum temperature for pollen germination of strawberries was 30 ℃ for Seolhyang and 25 ℃ for Maehyang, and Seolhyang had a higher pollen germination rate than that of Maehyang. The addition of polyamines, namely spermine and putrescine to the medium improved the pollen germination rate and spermine treatment showed a better effect than putrescine treatment. The proper polyamine type and treatment concentration for enhancing the potency of pollen germination was 500 μM of spermine for both Seolhyang and Maehyang, which improved the pollen germination rate by 19-23% compared with that of the control. However, combined treatment of spermine and putrescine, resulted in a lower germination rate lower than that of the single treatment. Our results indicated that the treatment of polyamines during flowering in protected cultivation of strawberrise can improve the fruiting rate by overcoming the problem of poor pollen germination due to low temperature.

The purpose of this study was to identify learning topics linked to Sustainable Development Goals(SDGs) in the dietary life unit of middle school technology and home economics textbooks and to develop teaching-learning plans and learning materials to verify the feasibility and field suitability. This study was carried out through analysis, design, development, and evaluation stages, and the results are as follows. First, in the analysis stage, the dietary life contents of the five home economics textbooks written based on the 2015 revised curriculum were analyzed, and dietary life-related goals were extracted from the 169 SDG targets to reorganize the learning topics linked to the contents of the textbooks. Second, in the design stage, the overall goal of the entire class was set and each session was designed by selecting the learning goals, learning topics, and learning contents, reflecting the SDGs related to the session to be developed. Based on the analyses of textbooks and the SDGs related to dietary life, the themes of 'desirable eating habits of adolescents', 'food production', 'food distribution', and 'food consumption and disposal' were extracted. Third, in the development stage, a total of 11 teaching-learning plans and student worksheets were developed, and an evaluation sheet was developed for expert verification. Fourth, in the evaluation stage, the feasibility and field suitability of the teaching-learning plans were verified by 5 home economics teachers. Learning goals, learning contents, connectivity to related SDGs, and feasibility of teaching-learning plan were evaluated, and based on the assessment results, teaching-learning plans were revised.

This paper describes a design of an 8-bit 100KSPS 1mW CMOS A/D Converter. Using a novel systematic offset cancellation technique, we reduce the systematic offset voltage of operational amplifiers. Further, a new Gain amplifier is proposed. The proposed A/D Converter is fabricated with a $0.6{\mu}m$ single-poly triple-metal n-well CMOS technology. INL and DNL is within ${\pm}1LSB$, and SNR is about 43dB at the sampling frequency of 100KHz. The power consumption is $980{\mu}W$ at +3V power supply. 본 논문에서는 1mW의 낮은 전력소모를 갖는 8-bit 100KSPS CMOS A/D 변환기를 설계, 제작하였다. Cyclic 구조를 갖는 A/D 변환기에서 발생하는 연산증폭기의 시스템적인 offset 전압을 효과적으로 감소시키기 위해, 새로운 시스템적인 offset 전압 제거 기술을 제안하였다. 또한 기존 Gain 증폭기에서 발생하는 오차를 감소시키기 위해 완전 차동 구조의 Gain 증폭기를 설계하였다. 제안된 A/D 변환기는 $0.6{\mu}m$ single-poly triple-metal n-well CMOS 공정을 사용하여 제작되었으며, +3V 단일 공급전압에서 DNL과 INL은 ${\pm}1LSB$ 이내로 측정되었고, 100KHz의 샘플링 주파수에서 43dB의 SNR를 갖는다. 측정된 최대전력소모는 $980{\mu}W$로 나타났다.

본 논문에서는 주어진 단백질 분자에 대해 3차원 보로노이 다이어그램을 계산하는 알고리즘을 제안한다. 분자는 반경이 서로 다른 구의 집합으로 표현되며, 각 구의 반경은 원자의 반데르바스 (van der Waals) 반경에 대응한다. 보로노이 다이어그램은 3차원 공간을 복셀(voxel)의 집합으로 분할한 뒤, 보로노이 다이어그램을 포함하는 복셀을 보수적으로 추출함으로써 구성된다. 분자의 계층적 성질을 이용하여 BVH(bounding volume hierarchy)를 구성하고, CUDA 프로그래밍을 통하여 그래픽 하드웨어 가속을 활용함으로써 계산 시간 효율성을 높인다. 공간이 최대 $2^{24}$개의 복셀로 분할될 경우, 단일 코어 CPU로 구현하는 알고리즘에 비해 계산 속도가 323배 가량 향상 되었다. We present an algorithm that computes a 3 dimensional Voronoi diagram for a protein molecule in this paper. The molecule is represented as a set of spheres with van der Waals radii. The Voronoi diagram is constructed in the 3D space by finding the voxels containing it. For the feasibility of the computation, we represent the molecule as a BVH (bounding volume hierarchy), and our system is accelerated by modern graphics hardware with CUDA programming support. Compared to single-core CPU implementations, experimental results show 323 times faster performance in the computation time, when the space is partitioned into $2^{24}$ voxels.

Post-herpetic neuralgia(PHN) is a chronic pain syndrome associated with the reactivation of a primary infection with varicella zoster virus(chinken pox), which leads to a chronic infection of dorsal root ganglia. The most common risk factor for shingles and its potential sequela, PHN, is advanced age. For a significant number of patients, the pain following healing of shingles can persist for months to years. If this pain, classified as PHN, persists longer than one month. PHN often leads to depression, disrupted sleep, decreased productivity, and utilization of health care. We treated a 60 year-old female patient who suffered pain and headache after Stellate Ganglion Blocks(SGB). In identifying points for differentiation of syndrom(辨證), this subject was diagnosed as Yangmyeong Merdian wind-heat syndrom(陽明經風熱證) and was administered Seungmagalgeuntanggamibang(revised Shengmagalgen-tang, 升麻葛根湯加味方). To ease pain, Western medication was administered as well. After fourteen days of treatment, pain and other symptoms improved.

기록을 둘러싼 업무환경의 변화, 조직의 변화, 시스템의 변화 등은 기록 에 대한 개념을 변화시켰다. 2001년도에 제정된 기록관리 국제표준인 ISO 15489 역시 이에 조응하기 위해 15년 만에 개정을 이루었다. 본 연구는 2016년에 개정된 기록관리 국제표준인 ISO 15489를 통해 급변하는 디지털 혁명 속에서 기록을 바라보는 개념의 변화를 살펴보고자 하였다. ISO 15489의 개정 배경 및 개정 전·후의 조항을 검토하고, 확장된 기록의 개 념을 살펴봄으로써 구체적으로 개정판이 추구하는 바를 알아보고자 한다. A new digital work environments, organizational changes, and system changes surrounding the records have changed the concept of records. ISO 15489, the international standard for records management established in 2001, has also been amended in 15 years to accommodate this. The study examines the characteristics of the revised ISO 15489, its elements and concept, in 2016. By comparing the old and new elements of ISO 15489 in detail, we intend to understand the nature of the revision and the basic framework of new standard.
