Objective: To compare correlations between pulmonary function test (PFT) results and different reconstruction algorithms and to suggest the optimal reconstruction protocol for computed tomography (CT) quantification of low lung attenuation areas and airways in healthy individuals. Materials and Methods: A total of 259 subjects with normal PFT and chest CT results were included. CT scans were reconstructed using filtered back projection, hybrid-iterative reconstruction, and model–based IR (MIR). For quantitative analysis, the emphysema index (EI) and wall area percentage (WA%) were determined. Subgroup analysis according to smoking history was also performed. Results: The EIs of all the reconstruction algorithms correlated significantly with the forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) (all p < 0.001). The EI of MIR showed the strongest correlation with FEV1/FVC (r = -0.437). WA% showed a significant correlation with FEV1 in all the reconstruction algorithms (all p < 0.05) correlated significantly with FEV1/FVC for MIR only (p < 0.001). The WA% of MIR showed the strongest correlations with FEV1 (r = -0.205) and FEV1/FVC (r = -0.250). In subgroup analysis, the EI of MIR had the strongest correlation with PFT in both eversmoker and never-smoker subgroups, although there was no significant difference in the EI between the reconstruction algorithms. WA% of MIR showed a significantly thinner airway thickness than the other algorithms (49.7 ± 7.6 in ever-smokers and 49.5 ± 7.5 in never-smokers, all p < 0.001), and also showed the strongest correlation with PFT in both ever-smoker and never-smoker subgroups. Conclusion: CT quantification of low lung attenuation areas and airways by means of MIR showed the strongest correlation with PFT results among the algorithms used, in normal subjects.

Background : Alpha-linolenic acid is a type of omega-3 fatty acid and has been reported to be found at a remarkably high content in seeds of perilla (Perilla frutescens). The purpose of this study was to investigate the fatty acid compositions in 45 perilla accessions collected from Russia and recommend the potential genetic resources related to their fatty acid compositions. Methods and Results : The 45 accessions of perilla seeds which were collected from Russia were used for the study. Perilla seed oil was recovered using hexane in a soxhlet extraction method. The fatty acid compositions were analyzed using gas chromatography. The total oil content was ranged between 28.39 and 46.89%. The compositions of palmitic, stearic, oleic, linoleic and linolenic acid ranged from 5.57 to 7.09%, 1.16 to 2.27%, 11.83 to 19.55%, 11.92 to 16.71%, and 59.19 to 67.28%, respectively. Cultivars 'Dayu', 'Daeyu' and 'Anyu' showed lower linolenic acid composition compared to the average value of linoleic acid in perilla germplasms collected from Russia. Cluster analysis based on the fatty acid composition of the 45 perilla accessions segregated into three groups. Group Ⅰ characterized as higher palmitic, stearic and oleic acid compositions compared to other groups. Group Ⅱ which contained 12 accessions had high total oil and linoleic acid composition. Group Ⅲ characterized as a higher linolenic acid composition compared to other groups (p < 0.001). Oleic acid showed a significant negative correlation (r = -0.825) with linolenic acid. Principal component analysis (PCA) revealed that the first two principal components together explained 74.4% total variation. Conclusion : Our results indicated that accessions IT235818, IT235820, IT226739 which exhibited high linolenic acid composition could be useful to develop new functional vegetable oil materials.

The purpose of this study is to suggest the direction of invention education in elementary teacher training colleges and to increase the effectiveness of invention education by pre-service elementary teachers by confirming the importance and performance of core invention competencies that pre-service elementary teachers think. To do this, a survey was conducted on 274 prospective elementary school teachers who are attending B education university, and the results are as follows. First, prospective elementary school teachers valued core invention competency regardless of gender and whether or not they had experience in invention education, and both female and male students valued personal competency as the most important, followed by creative competency and technical competency Second, looking at the relationship between the importance and performance of pre-service elementary school teachers' invention core competencies, regardless of gender or invention education experience, the importance for all large domains of invention core competencies was high at 4.25 to 4.38, but the performance was 3.69. ~ 4.02, showing 3 points in most sub-domains, which is low compared to importance. Third, as a result of the IPA Matrix analysis of the core invention competency of pre-service elementary school teachers, the fourth quadrant, which is an area of central interest that requires intensive efforts to improve the low performance level, is an area that is considered important but has low performance. 'Creative competency', among the sub-areas, 'science and technology utilization ability' and 'creativity' areas were located. In conclusion, education to improve technical and creative competencies among the large areas of inventive core competencies should be strengthened, and the performance level of preparatory elementary school teachers for inventive core competencies does not reach the importance level, so the ability to perform in large areas of inventive core competencies Various education such as invention education and invention club activities that can improve students' skills are needed. 이 연구는 예비 초등교사가 생각하는 발명핵심역량에 대한 중요도와 수행도를 확인하여 초등교원양성대학에서의 발명교육의 방향을 제시하고 예비 초등교사의 발명교육의 효과를 높이는데 목적이 있다. 이를 위하여 B 교육대학교에 재학 중인 예비 초등교사 274명을 대상으로 설문을 실시하였으며 그 결과는 다음과 같다. 첫째, 예비 초등교사는 성별과 발명교육 경험 유무에 관계없이 발명핵심역량에 대해 중요하게 생각하고 있었으며, 여학생과 남학생 모두 인성적 역량에 대해 가장 중요하게 생각하였고, 창의적 역량, 기술적 역량 순으로 높게 나타났다. 둘째, 예비 초등교사의 발명핵심역량에 대한 중요도와 수행도 간의 관계를 살펴보면 성별이나 발명교육 경험과 관계없이 모든 발명핵심역량의 대영역에 대해 중요도는 4.25~4.38로 높은 수준이지만, 수행도는 3.69~ 4.02로 대부분의 하위영역에서 3점대로 중요도에 비해 낮은 수준이다. 셋째, 예비 초등교사의 발명핵심역량 IPA Matrix 분석 결과 중요하게 생각하고 있으나 수행도가 낮은 영역으로 낮은 수행도를 높이기 위한 집중적인 노력이 필요한 중점 관심 영역인 제 4사분면에는 발명핵심역량의 대영역 중 ‘창의적 역량’, 하위영역 중 ‘과학 기술 활용 능력’, ‘창의성’ 영역이 위치하고있다. 결론적으로 발명핵심역량의 대영역 중 기술적 역량과 창의적 역량을 향상하기 위한 교육이 강화되어야 하며 발명핵심역량에 대해 예비 초등교사의 수행도는 중요도에 미치지 못하므로 발명핵심역량의대영역에 대한 수행 능력을 향상할 수 있는 발명교육, 발명 동아리 활동 등의 다양한 교육이 필요하다.

This paper explores the narrative strategy and the thematic consciousness of Shi Tuo’s novel Malan. Malan is Shi Tuo’s first full-length novel. In this novel, one can find thematic consciousness that consistently penetrates other works by Shi Tuo. In his novels, one can discover elements of social criticism, but it is evident that he was more captivated by the fate of man in this work. Shi Tuo described not heroes, but ordinary people; and he was critical of humans’ weaknesses at the same time showed a deep compassion for them Malan describes the growth and failure of three men and women and demonstrates that the fate of an individual cannot be separated from the circumstances of the time they were living. No matter how hard humans struggle, they are not free from their fates nor from the society to which they belong. Nevertheless, humans do not blindly accept nor despair at their fates, but rather have the nobility to fight their fates. Deeply-entrenched futility and pessimism are distinctive of Shi Tuo’s work. However, Malan demonstrates a sense of optimism that is usually lacking in his other works. This work depicts a generation that has lost its values, and a man who has lost his ideals and wanders helplessly. Furthermore, the novel portrays Shi Tuo’s deep insight into life and a sense of futility, which have transcended time and still are meaningful to the present.

김다정,최승원 한국임상심리학회 2020 한국심리학회지: 임상심리 연구와 실제 Vol.6 No.4

본 연구는 불면증 인지행동치료(Cognitive Behavioral Therapy of Insomnia: CBT-I)의 효과를 생리심리학적 관점에서 규명하기 위해 시행되었다. 연구대상은 다른 정신과적 장애나 수면무호홉증, 일주기리듬 수면장애를 충족하지 않으며 수면의 어려움을 시사하는 불면증 심각도 척도(Insomnia Severity index: ISI) 점수가 15점 이상, 수면의 질(Pittsburgh Sleep Quality Index: PSQI)점수가 6점 이상을 나타낸 참가자들이며, 이들을 치료집단과 대기통제집단에 무선할당 하였다. 8명의 치료집단은 6회기의 불면증 인지행동치료를 받았고, 9명의 대기통제집단은 6주간 아무런 처지를 받지 않았다. CBT-I의 효과검증을 위해 치료집단과 대기통제집단의 치료 전과 후에 휴식기 정량적 뇌파, 심박변이도를 측정하였고, 수면 관련 자기보고 척도를 실시하였으며, 스마트 웨어러블 기기 및 수면일지 작성을 통해 수면 양상을 파악하였다. 연구 결과, 치료집단은 대기통제집단보다 고주파 대역인 Beta 주파수 대역의 파워감소, 수면 관련 자기보고 척도 점수의 감소, 수면 효율성과 수면만족도가 증가하였음을 확인하였다. 본 연구는 불면증 인지행동치료의 효과를 신경생리학적 과각성 지표인 고주파 대역의 파워 감소를 통해 확인하였고, 기존의 불면증 인지행동치료 효과 검증에서 사용되는 자기보고식 측정 뿐 만 아니라, 객관적 자료인 스마트 웨어러블 기기의 수면 정보를 활용하였다는 점에서 의의가 있다.
