Preliminary Development of a Scale for the Measurement of Information Avoidance
Kap-Seon KIM(Kap-Seon KIM) 한국웰빙융합학회 2023 웰빙융합연구 Vol.6 No.1
Purpose: The purpose of this study is a preliminary study to develop a comprehensive information avoidance scale that includes various search contexts. Research design, data and methodology: This study is a part of exploratory sequential design of mixed method for the development of information avoidance scale. Based on the themes derived from the analysis of the in-depth interview data collected in the qualitative research of the first stage of the study, 45 preliminary items on information search and avoidance were constructed. The factors related to information searching included information recognition, information seeking purpose, and information search expectations. Individual, information, time, and system factors were related to information avoidance. Pearson's correlation analysis was performed for the correlation between factor items, and Cronbach's alpha analysis was performed for the reliability analysis of the items. Exploratory factor analysis was applied to examine the construct validity of 35 items of information avoidance. Results: Among the information avoidance items, one of the less relevant among information purpose items, two information factor items, and one time factor item were excluded. Conclusions: A secondary survey should be conducted to confirm the validity and reliability of the scale composed of adjusted items (35) based on the results of exploratory factor analysis. The strength of this preliminary scale is that it was developed based on vivid qualitative data of ordinary people who had experiences of search and avoidance in various search contexts.

교정이나 악교정 수술 환자에서 치료계획 수립과 치료결과의 평가를 위해서 지금까지 많은 수평기준선이 사용되고 있으나 정확성과 재현성 등의 문제가 존재하고 있으며, 더욱 객관적인 수평기준선이 설정될 수 있다면 교정학 분야에서 많은 발전이 기대될 수 있을 것이다. 이에 본 연구에서는 한국 성인의 부정교합군과 성별에 따른 Sella-Nasion(SN) 평면과 Frankfort-Horizontal(FH)평면이 이루는 각도 및 FH평면과 다른 수평면 간의 상관 관계를 조사하기 위하여 먼저 임상검사를 시행하여 총 600여명을 대상으로 측모두부규격 방사선사진을 촬영하였다. 계측결과를 바탕으로 연구대상을 골격성 Ⅰ급 부정교합군 또는 정상교합군(남 50, 여 50), 골격성 Ⅱ급 부정교합군(남 50, 여 65), 골격성 Ⅲ급 부정교합군(남 50, 여50)으로 분류한 후 10개의 항목을 평가하여 다음과 같은 결론을 얻었다. 1. SN 평면과 FH평면이 이루는 각도는 부정교합에 따른 차이는 없었으나 성별 간에는 세 부정교합군 모두에서 차이를 보여 남자는 7.47±2.40˚, 여자는 8.93±2.72˚ 였다. 2. SN 평면 또는 FH 평면과 Mandibular Plane이 이루는 각은 모든 부정교합군에서 여자가 남자보다 컸으며, 골격성 Ⅱ급 부정교합군과 Ⅲ급 부정교합군이 Ⅰ급 부정교합군보다 큰 각도를 나타내었다. 3. FH 평면과 Palatal Plane이 이루는 각은 부정교합군 및 성별에 따른 차이를 보이지 않고 비교적 일정하였다. 4. Gonial angle은 남녀 모두 Ⅲ급 부정교합군이 다른 두 부정교합군보다 큰 각도를 보였다. The purpose of this study was to investigate the angle formed by the Sella-Nasion(SN) plane and Frankort-Horizontal(FH) plane and evaluate the correlation and difference of the FH plane to other horizonatal reference plane. Through this study we hope to present a basis for selecting a horizontal reference plane which can be implemented in cephalometric studies and in surgical orthodontic treatment planning. 600 subjects were chosen following a clinical examination and lateral cephlometric X-rays were taken. According to cephalometric analysis the subjects were classified into 3 groups; Skeletal Class I malocclusion or normal occlusion group(male 50, female 50), Skeletal Class Ⅱ malocclusion group(male 50, female 65) and Skeletal Class Ⅲ malocclusion group(male 50, female 50). The results were as follows. 1. The angle formed by the SN plane and FH plane showed no difference among the malocclusion groups, but there was a significant sex difference. For males the angle measured was 7.47˚±2.40˚ whereas for females it was 8.93˚±2.72˚. 2. The angle formed by the SN plane or FH plane and Mandibular plane was higher in females for all malocclusion groups. This angle in the Skeletal Class I malocclusion group was lower than in the other two groups. 3. There was no difference among the sexes or malocclusion groups considering the angle formed by the FH plane and Palatal plane. 4. The gonial angle in the Skeletal Class Ⅲ malocclusion group was higher than in the Skeletal Class I and Class Ⅱ malocclusion groups in both sexes.
Nucleotide Sequence on Upstream of the cdd Locus in Bacillus subtilis
Kim, Kye-Won,Hwang, Seon-Kap,Suh, Joo-Won,Song, Bang-Ho,Hong, Soon-Duck,Kim Jong-Guk 한국미생물 · 생명공학회 1995 Journal of microbiology and biotechnology Vol.5 No.3
A 3,346 by of the cdd upstream region in Bacillus subtilis was sequenced from the pSO1 (Song BH and J Neuhard. 1989. Mol. Gen. Genet 216: 462-468) and sequence homology was searched to the known genes in Genbank and European Molecular Biology Laboratory databanks. Five complete and one truncated putative coding sequences deduced from the nucleotide sequence were found through the ORF searching by Genetyx and Macvector software, and one of them was identified as the dgk (diacylglycerol kinase) gene and another, a truncated one, as the phoH (phosphate starvation-inducible gene) gene. The B. subtilis dgk gene, having a role for response to several environmental stress signals, revealed an open reading frame of 134 amino acids with 43.1% of sequence identity to the Streptococcus mutans dgk gene. The carboxy terminal 59 residues of the truncated phoH gene showed 52.7% and 34.5% of sequence identity in amino acids with the corresponding genes of Mycobacterium leprae and Escherichia coli. The four remaining coding sequences consisting of 115, 421, 91, and 91 residues were thought to be unknown ORFs because they have no significant similarity to known genes.

Kim, Hye Ryeon,Choi, Yu Na,Kim, Seon Hye,Kang, Ha Ra,Lee, Yoon Joo,Jung, Chan Yung,Cho, Hyun Seok,Kim, Kyung Ho,Kim, Kap Sung,Kim, Eun Jung Korean AcupunctureMoxibustion Medicine Society 2017 대한침구의학회지 Vol.29 No.3
Objectives : The aim of this study was to report the effect of Korean medical therapy on pain and dysfunction after anterior cruciate ligament (ACL) reconstruction. Methods : A 25-year-old man experienced severe pain after right ACL reconstruction surgery. He received Korean medical treatments such as acupuncture, herbal medicine, and physiotherapy from July 10, 2014 to August 2, 2014. Results : After the treatments, his visual analogue scale scores generally decreased and the range of motion of the right knee improved from $0^{\circ}$ to $90^{\circ}$. Furthermore, the Knee Infury and Osteoarthritis Outcome Score increased from 99 to 142. Conclusion : The findings suggest that Korean medical treatments might be effectively used to treat pain and dysfunction after soft-tissue surgeries such as ACL reconstruction. Nevertheless, further research is warranted because of the limited sample size of this study.
투과전자현미경을 이용한 나노구조 WC-Co계 용사코팅층의 미세조직 연구

The detailed microstructural features of WC-Co nanocomposite coating, manufactured by high velocity oxy-fuel spraying, have been characterized by high resolution transmission electron microscopy and computer-aided image processing. The coating was built up by depositing many individual droplets that experience different thermal histories during flight, developing an inhomogeneous microstructure. The nanocomposite coating contained very high amounts of non-WC phases including W₂C, W, i-carbide and amorphous Co-rich phase. The unreacted WC particles were also retained in the coating, with similar size and morphology in the feedstock powder, and had stacking faults with 116<1213> atomic displacement vectors. Two different types of near-spherical W₂C particles were formed by either direct decomposition of WC into W₂C and C or precipitation from liquid Co-W-C, which was attributed to the extent of feedstock melting and decarburization in specific droplets. The different formation mechanism yielded a significant difference in W₂C particle size in the coating. Metallic W particle and fl-carbide were also formed in specific locations in the coating. Rapid solidification promoted the formation of amorphous binder phase in which large amounts of W and C elements were dissolved in Co-rich matrix. (Received September 30, 2004)
Nucleotide sequence analysis of the 5S ribosomal RNA gene of the mushroom tricholoma matsutake
Hwang, Seon-Kap,Kim, Jong-Guk The Microbiological Society of Korea 1995 The journal of microbiology Vol.33 No.2
From a cluster of structural rRNA genes which has previsouly been cloned (Hwang and Kim, in submission; J. Microbiol. Biotechnol.), a 1.0-kb Eco RI fragment of DNA which shows significant homology to the 25S and rRNA s of Tricholoma matsutake was used for sequence analysis. Nucleotide sequence was bidirectionally determined using delection series of the DNA fragment. Comparing the resultant 1016-base sequence with sequences in the database, both the 3'end of 25S-rRNA gene and 5S rRNA gene were searched. The 5S rRNA gene is 118-bp in length and is located 158-bp downstream of 3'end of the 25S rRNA gene. IGSI and IGS2 (partial) sequences are also contained in the fragment. Multiple alignment of the 5S rRNA sequences was carried out with 5S rRNA sequences from some members of the subdivision Basidiomycotina obtained from the database. Polygenetic analysis with distance matrix established by Kimura's 2-parameter method and phylogenetic tree by UPGMA method proposed that T. matsutake is closely related to efibulobasidium allbescens. Secondary structure of 5S rRNA was also hypothesized to show similar topology with its generally accepted eukaryotic counterpart.
