본 연구는 아동청소년 교우관계문제검사(KIPR)에 잠재되어 있는 요인구조를 밝히고 검증하여 이 검사의 심리적 특성을 밝히고 해석적 유용성을 높이는데 목적이 있다. 이를 위해 경남지역 3개 초등학교 4~6학년 아동 616명을 대상으로 아동청소년 교우관계문제검사를 실시하였고 그 중 578명의 자료를 분석하였다. 연구결과를 요약하면 다음과 같다. 첫째, 3요인과 4요인 모형을 설정하여 탐색적 요인분석을 실시한 결과 3요인 모형이 적합한 것으로 나타났다. 3요인 모형에서 요인 1은 아동청소년 교우관계문제검사의 비주장성(C5), 사회적 억제(C4), 냉담(C3), 과순응성(C6) 원형척도의 문항들로 구성되어 있어서 "자신감 결여와 사회적 위축", 요인 2는 통제지배(C1), 자기중심성(C2) 원형척도의 문항들로 구성되어 있어서 "공격성과 타인조종", 요인 3은 자기희생(C7), 과관여(C8), 과순응성(C6) 원형척도의 문항들로 구성되어 있어서 "과잉배려"로 명명하였다. 둘째, 확인적 요인분석을 실시한 결과 3요인 모형은 4요인 모형보다 수집된 자료를 잘 반영하고 있었고(RMSEA=.054), 적합도는 만족할 수준은 아니지만 수용할 수 있는 수준이었고(CFI=.786), 모형의 간명성 또한 적합한 것으로 나타났다(PCFI=.733). 본 연구에서는 교우관계원형에서 상관계수가 높은 인접한 척도끼리는 동일한 요인으로 묶여지는 것을 확인하였고 이를 통해 8개의 원형척도를 망라하는 상위의 대표적인 요인척도를 구성하는데 필요한 근거를 제공하여, 이 검사의 해석적 유용성을 높였다는 점에서 의의가 있다고 생각된다. The purpose of this study is to reveal and confirm the factor structure inherent in the Korean inventory of peer relationships(KIPR; Sang-Hwang Hong, et al., 2009) in order to strengthen the interpretive usefulness of the test. For this purpose, the inventory was administered to the total of 616 children in the fourth through sixth grades in three elementary schools located in Gyungnam area, and the data from 578 of them were analyzed. The results of the study can be summarized as follows. First, as a result of the exploratory factor analysis of 3-factor and 4-factor models, the 3-factor model was found to be more appropriate. In the 3-factor model, the factor 1 is named "Lack of Self-Confidence and Social Withdrawal" as it consists of such circumplex scale items as Non-Assertiveness (C5), Social Avoidance (C4), the Cold (C3), and Too Submissive (C6). The factor 2 is named "Too Aggressive and Controlling" and consists of items Too Controlling (C1) and Hard to be Supportive (C2). The factor 3 is named "Too Caring" and consists of items Too Responsible (C7), Over Involvement (C8), and Too Submissive (C6). Second, as a result of the confirmatory factor analysis, the 3-factor model, in comparison to the 4-factor model, was found to better reflect the collected data(RMSEA=.054), its goodness of fit was not satisfactory but within the acceptable range(CFI=.786), and its power of simplicity and clarity was also adequate(PCFI=.733). In the current study, through the exploratory and confirmatory factor analyses of scores from the Korean inventory of peer relationships circumplex scales, scales within the peer relationship circumplex model that are near each other and are highly correlated were confirmed to be grouped together as same factors. I believe the main merit of the study lies in the above result having provided the necessary foundation for forming the superordinate and representative scale that encompasses the eight circumplex scales, which enhances the test's interpretive usefulness.

Background: Onychomycosis (OM) is the most common nail disorder. Though there are treatment guidelines, overall cure rate is not sufficient so that diverse regimens are applied in real-world. Objectives: This study was aimed to investigate the patterns of systemic antifungal for OM in actual practice. Methods: Patients with OM who took oral antifungal medication and are in treatment-free state currently. Patterns of medication were categorized according to the number of treatment session and medication respectively. Three months were defined as sufficient period (SP) in each session for terbinafine, itraconazole, 6 months for fluconazole. Results: A total of 280 patients were enrolled. Single session (SS) with single drug (SD) (n=215) was the most common followed by multi-session (MS) with SD (29), SS/MD (20) and MS/MD (16). Patients with at least one SP session was 60.7% and showed better complete cure rate compared with the rest (20.6 vs 4.5, p<0.05). SS/SD showed mean duration of 3.8 months (0.25~27) and 52.1% satisfied SP while uncontrolled cessation was the hightest (53.5%). MS/MD included 2 or 3 sessions with up to 3 drugs and showed mean session duration of 4.5 (1st), 4.3 (2nd), 10.0 (3rd) month respectively with mean interval of 45.3 (1st), 18.3 (2nd) month. Conclusion: This study showed diverse spectrum in OM treatment. It is suggestive that individualization based on sufficient period and fair compliance might be important strategy for OM.
The Plant Cellular Systems for Plant Virus Movement
Hong, Jin-Sung,Ju, Ho-Jong The Korean Society of Plant Pathology 2017 Plant Pathology Journal Vol.33 No.3
Plasmodesmata (PDs) are specialized intercellular channels that facilitate the exchange of various molecules, including sugars, ribonucleoprotein complexes, transcription factors, and mRNA. Their diameters, estimated to be 2.5 nm in the neck region, are too small to transfer viruses or viral genomes. Tobacco mosaic virus and Potexviruses are the most extensively studied viruses. In viruses, the movement protein (MP) is responsible for the PD gating that allows the intercellular movement of viral genomes. Various host factors interact with MP to regulate complicated mechanisms related to PD gating. Virus replication and assembly occur in viral replication complex (VRC) with membrane association, especially in the endoplasmic reticulum. VRC have a highly organized structure and are highly regulated by interactions among the various host factors, proteins encoded by the viral genome, and the viral genome. Virus trafficking requires host machineries, such as the cytoskeleton and the secretory systems. MP facilitates the virus replication and movement process. Despite the current level of understanding of virus movement, there are still many unknown and complex interactions between virus replication and virus movement. While numerous studies have been conducted to understand plant viruses with regards to cell-to-cell movement and replication, there are still many knowledge gaps. To study these interactions, adequate research tools must be used such as molecular, and biochemical techniques. Without such tools, virologists will not be able to gain an accurate or detailed understanding of the virus infection process.

Purpose: To investigate the incidence and risk factors of cystoid macular edema (CME) after silicone oil (SO) injection for retinal detachment. Methods: Fifty-eight patients with retinal detachment treated by vitrectomy with SO tamponade during 2011 to 2015 were retrospectively assigned to CME and non-CME groups. Patients underwent complete ophthalmological examination, including color fundus photography and preoperative and postoperative optical coherence tomography. Risk factors for CME during SO tamponade were determined by regression analyses. Results: Of the 58 eyes, 21 (36.2%) exhibited CME. The presence of posterior staphyloma in the CME group was significantly more frequent than in the non-CME group (p = 0.026). There were no significant differences in other demographic or clinical characteristics between the CME and non-CME groups. Significant correlations were observed between CME after vitrectomy with SO tamponade and the presence of posterior staphyloma (odds ratio, 4.03; p = 0.031). Of the 21 eyes with CME, 13 underwent SO removal, among which 11 experienced resolution of CME with or without further intervention. Conclusions: The presence of posterior staphyloma is significantly associated with CME after vitrectomy with SO tamponade. Patients with retinal detachment exhibiting posterior staphyloma should be evaluated for potential CME during SO tamponade.

PURPOSE:: Reconstruction of bone defects is possible through distraction osteogenesis using small bone transport discs. The aim of this study was to evaluate the usability of transport disc distraction osteogenesis (TDDO) in the reconstruction of skull defects in an animal experiment. METHODS:: Eleven mongrel female dogs were used. Craniectomy (33 × 15 mm) was performed on both sides of the parietal bone symmetrically. On the experimental site, the 7 × 15-mm transport bone disc was used for TDDO. The control site was left in the defect state. An external distraction device was used. The latency period was 5 days, the rate of distraction was 1 mm/d, and distraction was done for 26 days. After a 6-month consolidation period, a computed tomographic scan was performed. The area of regenerated bone was measured from the computed tomographic scan. The hardness was checked on the regenerated bone and the normal bone. A histologic examination of the regenerated bone was done. RESULT:: Eight cases were included in the evaluation, and 3 cases were excluded because they showed early escape of the distraction device. The mean (SD) area of the regenerated bone was 57.1% (26.3) in the experimental site and 41.8% (21.3) in the control site, which was not a statistically significant difference (P > 0.05). The mean (SD) hardness was 0.50 (0.17) MPa in the experiment site and 0.55 (0.29) MPa in the normal calvarial bone; the difference was not statistically significant (P > 0.05). On histologic examination, membranous ossification was found in the regenerated bone in the experimental site. CONCLUSIONS:: Transport disc distraction osteogenesis can induce new bone formation with hardness comparable to that of a normal bone. However, the amount of regenerated bone is not sufficient to allow TDDO to be substituted for conventional autogenous bone grafts.
