Several entomopathogenic fungi have been exploited to be developed into biological control agents in insect pest management. The beet armyworm, Spodoptera exigua, is a serious insect pest infesting various crops, but not effectively controlled by commercial chemical pesticides due to its high insecticide resistance. A fungal isolate was isolated from S. exigua larvae collected from cabbage field in Andong, Korea. The fungus could be cultured in potato dextrose agar. Larvae of S. exigua injected with the cultured conidia showed a potent entomopathogenicity. To identify the fungus isolate, its internal transcribed space (ITS) and surrounding partial 18S/28S regions were sequenced. The ITS sequence was highly matched (99%) to that of Nomuraea rileyi. Morphological characters of its hyphae and conidia were well fit to those of known N. rileyi. This study reports the first record of an entomopathogenic fungus, N. rileyi, in Korea.

Purpose: The purpose of this study was to develop and validate the Communication Behavior Scale for nurses caring for people with Dementia (CBS-D). Methods: Based on communication accommodation theory, the initial items were generated through a literature review and interviews with 20 experts. Content and face validity of the initial items were assessed. Data from 486 nurses caring for people with dementia were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion-related validity, and internal consistency. Results: The final scale consisted of 18 items and four factors (discourse response management, interpersonal control, emotional expression, and interpretability) that explained 57.6% of the variance. Confirmatory factor analysis indicated that the theoretical model with 18 items satisfied all goodness-of-fit parameters. Criterion-related validity was shown by the Global Interpersonal Communication Competence Scale (r=.506, p<.001). Cronbach's alpha for the total scale was .88. Conclusion: The CBS-D can be used to measure the communication behavior of nurses caring for people with dementia.

We present 2-dimensional continuum radiative transfer modeling for EC53. EC 53 is a Class I YSO, which was brightened at $850{\mu}m$ by a factor of 1.5. This luminosity variation was revealed by the JCMT Transient Survey. The increase in brightness is likely related to the enhanced accretion. We aim to investigate how much increase of protostellar luminosity causes the observed brightness increase at $850{\mu}m$. Thus we modeled the SED of EC 53 both in the quiescence and (small scale) outburst phases, with and without the external heating from the interstellar radiation field (ISRF). We found that the internal protostellar luminosity should increase more to fit the observed flux enhancement if the ISRF is considered in the model.

Objectives: This study was conducted to develop a dental hygienist's job satisfaction scale and to evaluate its validity and reliability. Methods: A total of 34 preliminary questions were composed based on the components commonly defined in previous studies and in-depth interviews. Results: The results of the study were practice activity, professional satisfaction, income, working conditions, patient relations, and co-worker relations using the exploratory factor analysis. Goodness of fit of the model assessed using confirmatory factor analysis generally met the criteria. On verification of the internal consistency, the Cronbach's alpha for the factors were as follows: 0.821 for practice activity, 0.822 for professional satisfaction, 0.847 for income, 0.765 for working condition, 0.743 for patient relations, and 0.747 for co-worker relations, which implied that the measurement tool was reliable. Through exploratory and confirmatory factor analyses, a total of 24 items for six factors: six items for practice activity factors, four items for professional satisfaction, three items for income, four items for working conditions, three items for patient relationships, and three items for coworker relations. Conclusions: Based on the aforementioned results, the validity and reliability of the dental hygienist's job satisfaction measurement tool were satisfactory. Thus, it may be used for assessing the job satisfaction of the dental hygienists in future.

In this study, the characteristics of digital anthropometric methods were determined with case studies. These methods were broadly classified into two categories: non-wearable and wearable. Then, these categories were further classified into four types: 3D Scanning, mobile app, smart clothing, and smart tool Among the non-wearable types, the "3D scanning" technique was based on the use of 3D hardware equipment. With this technique, the body shape was measured and the internal body information was obtained. Therefore, it is used in fields of healthcare and fitness. Among the wearable types, "Smart clothing" involves a special clothing that measures human body and a smartphone application. Both the components are linked to a fashion platform, which is based on the measured sizes that help shoppers. The "Smart tool" has the characteristic of measuring only with smart tools and smartphone applications; it does not involve the measurement of images. The common advantage of digital anthropometric methods are as follows: they reduce the time and cost of measurement by enabling self-measurement. Moreover, simple measurements are used to determine the size of anthropometry. Thereafter, it accumulates this data to track the continuous changes in size. From an industrial point of view, digital anthropometric technology should be used to increase sales. The on-demand market can be expanded as global consumers would throng the Korean fashion market. For the consumer, an avatar should be created to fit the user's size. This would provide a fun experience to the user.

Objective: The purpose of this study is to test the psychometric properties of the Maternal Emotion Coaching Questionnaire (MECQ, Lim et al., 2018) in order to measure emotion coaching in mothers of preschoolers. Methods: A total of 316 preschoolers and their mothers participated in this study. Maternal emotion coaching was assessed by self-report and child emotion regulation ability was evaluated by the teacher. Data were analyzed with chi-square tests, reliability analysis, confirmatory factor analysis, latent profile analysis, and F-test. Results: Each item of the MECQ showed proper discriminative power. The MECQ and each subscale demonstrated adequate internal consistency and split-half reliability. Evidence of construct validity was provided by confirmatory factor analysis. The five-factor model including maternal attention, awareness, acceptance, empathy, and guidance showed a good fit. Results of the latent profile analysis revealed three profiles of emotion coaching: excellent, good, and poor. Preschoolers with mothers in the poor coaching profile showed significantly lower emotion regulation ability compared to those in the excellent or good coaching profiles, which suggested discriminative validity of the MECQ. Conclusion/Implications: The MECQ presents a reliable and valid tool to assess emotion coaching in mothers of preschool children and can thus be effectively used for mothers of preschoolers.

Contemporary fashion criticism tends to rely solely on the established art criticism process without consideration of the distinctive characteristics of fashion. Thus, this study aims to reveal the unique roles and characteristics of fashion criticism by recognizing it as an independent field in contemporary art with its own social significance. This study will first apply traditional art criticism models to analyze and explore contemporary fashion criticism's empirical content before uncovering the uniqueness of contemporary fashion criticism by content analysis. Contemporary fashion criticism discusses not just physical objects but various topics and ideas, as well. Accordingly, the existing criticism model was modified in this study to fit contemporary fashion criticism and organized into five stages: description of historical fashion, form description, external evaluation, interpretation, and internal evaluation. Commerciality, the human body, coordination, the critic's individuality, trends, and fashion-related persons were identified as key factors of contemporary fashion criticism's uniqueness. In conclusion, rather than build a single contemporary fashion model, this study found it more effective to create individual fashion criticism models suitable for detailed fields, as these enable the discussion of multifaceted topics in the fashion field. This study is expected to serve a meaningful guide for the fashion discourses.

연구목적: 본 연구의 목적은 냉간 정수압 성형법 (cold isostatic press forming)을 이용한 새로운 지르코니아 블록의 제조와 이를 이용한 코어와 완전 도재관의 적합도를 비교 평가하여 임상적 이용 가능성을 평가 하고자 함이다. 연구 재료 및 방법:지르코니아 분말 (KZ-3YE Type A)을 단일 압축 성형하여 블록의 형태로 제작 한 후, 냉간 정수압 성형하여 블록을 제작하고, 성형이 끝난 지르코니아 블록은 $1040^{\circ}C$의 온도에서 반 소결하였다. 대조군은 상용 제품 ($Everest^{(R)}$, KAVO, Biberach/$Ri{\beta}$.)을 이용하였다. $1450{^{\circ}C}$의 온도에서 완전 소결된 실험군 블록과 대조군 블록의 수축률을 측정하고 비교하였다. CAD/CAM을 이용하여 총 21개의 코어를 제작하고 세 그룹으로 나누었다. Group I은 대조군 블록을 이용해 7개의 코어를 제작하고, Group II는 실험군 블록을 이용해 7개의 코어를 제작하였다. Group III은 실험군 블록을 이용해 7개의 코어를 제작하고 도재 ($Cerabien^{TM}$)를 축성하여 완전 도재관을 제작하였다. 제작된 코어와 완전 도재관을 모형에 합착한 후 레진으로 매몰하여 치관 장축의 협설과 근원심 방향을 따라 절단하고 지대치와 코어 사이의 변연 간격과 내부 축면 간격 그리고 내부 교합면 간격을 SEM ($S-4700^{(R)}$)을 이용해 측정하였다. 모든 측정값은 평균과 표준편차를 계산하고, one-way ANOVA test를 시행하여 실험 결과를 분석하였고, 95%유의 수준으로 검정하였다. 결과:실험군과 대조군 블록의 수축률을 측정한 결과 실험군 블록의 수축률은 19.00%였고, 대조군 블록의 수축률은 20.09%로 실험군 블록의 수축률이 더 낮은 것으로 나타났다. 적합도 측정 결과 변연 간격의 측정값에서 Group II의값($29.67{\pm}6.58 {\mu}m$)이 Group I의값($36.84 {\pm}7.18 {\mu}m$)보다 통계적으로 유의하게 작은 것으로 나타났다. 또한 Group II와 Group III의 값 사이에서는 유의한 차이가 없었다. 내부 측면 간격의 측정값에서 Group III의값($32.23{\pm}6.33 {\mu}m$)이 Group I와 Group II의내부측면간격의값($37.57{\pm}6.81{\mu}m$, $38.14{\pm}6.81{\mu}m$)보다 큰 것으로 나타났다. 각 부위의 간격 측정결과 내부 교합면 간격의 값이 변연 간격 및 내부 축면 간격의 값보다 유의하게 큰 것으로 나타났다. 결론: 현재 상용중인 대조군 블록과 비교하여 냉간 정수압 성형법으로 제조된 실험군 블록의 적합도는 유의한 차이를 보이지 않았다. 변연 적합도는 실험군에서 더 우수하였으며 도재를 축성한 완전 도재관의 적합성이 약간 더 향상되는 경향을 보였다. 변연 적합도는 대조군과 실험군 모두에서 임상적으로 허용되는 양호한 수치를 보였다.
