This study examined the job satisfaction of nutritionists, and its effect on organizational commitment and turnover intention in public health centers. The response data of 174 nutritionists were analyzed. The overall average of job satisfaction was 3.94 out of 7 points, which was determined to be below ‘normal’; however, the job suitability of sub-factors scored 5.26, which was more than ‘normal’. The variables affecting job satisfaction that were provided by the respondents included job-related licenses (P<0.01) and co-nutritionists (P<0.01). Organizational commitment ranked ‘normal’ with a score of 4.35. Normative commitment (4.90) of the sub-factors was ‘normal’ or more, and differed when considering ‘age’ (P<0.01), ‘employment status’ (P<0.01), ‘salary per year’ (P<0.05), and ‘working area’ (P<0.05). The turnover intention was analyzed to be below ‘normal’ with 3.88 points, and the variables affecting turnover were significantly higher for subjects in their 20s (P<0.01), less than two job-related licenses (P<0.05), and less than two co-nutritionists (P<0.01). The four variables of job satisfaction, ‘business discretion’ (P<0.05), ‘work environment’ (P<0.01), ‘job suitability’ (P<0.01), and ‘reward’ (P<0.01), positively affected the organizational commitment. Moreover, organizational commitment had a mediating effect (P<0.01) on job satisfaction and turnover intention. Taken together, our results suggest that public health centers need to develop improvement plans for business discretion, work environment, job suitability and reward.

Multiple endocrine neoplasia type 1(MEN 1) is an autosomal dominantly inherited syndrome, characterized by the combined occurrence of tumors of the parathyroid glands, endocrine pancreas, and anterior pituitary gland. The MENIN gene, which is a kind of tumor suppressor gene, is located at the chromosomal locus 11q13. It consists of one untranslated exon and nine exons encoding the menin protein. We report a case of a 22-yearss-old woman with MEN type 1, who was proven to have a mutation in the MENIN gene. The patient was admitted because of repeated hypoglycemia. The fasting plasma glucose level was 32mg/dL. Seventy two hours fasting test showed an the insulin/glucose ratio as 0.33. Endoscopic ultrasonography detected multiple masses on the pancreas. The arterial -stimulated venous sampling(ASVS) with calcium showed sudden step up of insulin at the head and tail portions of the pancreas. The sellar MRI showed a pituitary mass that produced prolactin. Instead of a pathologic diagnosis from operational specimen, the genetic analysis revealed a mutation in the MENIN 1 gene(exon 2, 200~201insAGCCC) 저자들은 공복 시 발생하는 어지러움증, 발한을 주소로 내원한 22세 여자 환자에서 호르몬 검사와 방사선 검사 및 칼슘자극 선택정맥혈채혈검사 등을 통해 췌장 인슐린종, 프로락틴 분비 뇌하수체선종, 부갑상선 기능항진증을 함께 보인 제1형 다발성 내분비선종을 진단하고 유전자 검사결과를 통하여 이를 확진하였다. 이에 문헌 고찰과 함께 보고하는 바이다

Effects of a hybrid online and offline program for facilitating father-infant interactions in South Korea: a quasi-experimental study

박세은,Kyung-Sook Bang 한국아동간호학회 2022 Child Health Nursing Research Vol.28 No.2

Purpose: This study examined the effects of an educational program for fathers on improving father-infant interactions, child-rearing knowledge, and attachment. Methods: In this quasi-experimental study, the participants were recruited by convenience sampling among fathers with infants (2-6 months of age) residing in three districts of Seoul. Fifteen participants in the experimental group and 17 participants in the control group completed the follow-up investigation. A 5-week online and offline intervention program with five sessions was provided to the experimental group. The data were analyzed using generalized estimating equations (GEEs). Results: There was a significant difference in the change in father-infant interaction scores of the experimental group, especially in the caregiver aspect with a significance level of .100 in time and group-to-group interactions (B=6.46, p=.051, 95% confidence interval [CI]=-0.02-12.94). The changes between the groups and times were not statistically significant when it came to infant development knowledge and father-infant attachment. Conclusion: We conclude that hybrid online and offline education should be implemented as an effective method to improve fathers’ interactions with their children based on accurate knowledge about infant development.

박세은,이기욱,김혜영,손호현,장주혜 大韓齒科保存學會 2011 Restorative Dentistry & Endodontics Vol.36 No.4

Objectives: The usage of fluoride varnish for a moderate to low caries-risk group has not been well validated. This study aimed to evaluate the preventive and therapeutic efficacies of fluoride varnish on the initiated root caries. Materials and Methods: Ten premolars were sectioned into quarters, further divided into two windows, one of which was painted with Fluor Protector (1,000 ppm fluoride, Ivoclar Vivadent). An initial lesion with a well-preserved surface layer was produced by pH cycling. Scanned line analysis using energy dispersive spectrometry determined the weight percentages of Ca and P in the demineralized layer. Scanning Electron microscopy and confocal laser scanning microscopy (CLSM) evaluated the varnish-applied root surfaces. Results: The mean lesion depth (SD) was 12.3 (2.6) (single cycling) and 19.6 (3.8) (double cycling). Double cycling extended the lesion depth, but induced no more mineral loss than single cycling (p < 0.05). The mean weight percentages of Ca and P between groups with and without varnish were not significantly different (p < 0.05). A CLSM showed varnish remained within 15 of the surface layer. Conclusions: When a mild acid challenge initiated root tissue demineralization, the application of low-concentration fluoride varnish did not influence the lesion depth or the mineral composition of the subsurface lesion. 연구 목적: 우식 저 위험군에서 저 농도 불소 바니쉬가 초기 치근 우식 예방 및 치료에 미치는 영향을 검증하고자 한다. 연구 재료 및 방법: 건전한 하악 소구치 10개를 준비하여 치관부를 제거하고 협설, 근원심 방향으로 치아 장축에 평행하게 절단 후 백악-법랑질 경계부 4 mm 하방에서 절단하여 40개의 시편을 제작하였다. 각각의 치근 표면에 형성된 4 mm 1 mm 크기의 창에 Fluor Protector (1,000 ppm 불소 함유)를 도포하였다. 한 치아에서 나온 4 개의 시편을 다음과 같은 4개 실험군에 각각 배정하였다. A군: pH cycling 없이 불소 바니쉬 도포; B군: pH cycling시행 후 불소 바니쉬 도포; C군: 불소 바니쉬 도포 후 pH cycling시행; D군: pH cycling을 시행한 뒤 불소 바니쉬 도포 후 pH cycling 재 시행. 시편을 정중부에서 절단하고 단면 부위를 연마한 뒤 전자현미경으로 표면을 관찰하였다. X선 분광분석을 통하여 Ca과 P의 중량 비를 측정하고 공 초점 레이저 현미경으로 바니쉬가 도포된 치근 면을 관찰하였다. 결과: 치근 표면에는 평균 12.3 (2.6) (single cycling) 과 19.6 (3.8) (double cycling) 깊이의 우식이 형성되었다. 표층의 칼슘 함량은 정상 치근에 비해 유의할만한 차이가 없었으나(p > 0.05), 표층 하 탈회 영역의 칼슘 함량은 유의할만하게 감소하였다(p < 0.05). 불소 바니쉬의 적용은 건전한 치근이나 초기 우식이 있는 치근에 적용했을 경우 모두에서 유의할만한 차이를 가져오지 않았다(p > 0.05). 바니쉬의 치근 상아질 투과 깊이는 표면 15 이내에 한정되었다. 결론: 표층이 건전한 20 이내의 초기 치근 우식 병소의 양상과 산 공격에 대한 변화를 관찰한 결과, 저 농도의 불소 바니쉬를 단기간 적용하는 것은 치근의 탈회 반응에 영향을 주지 못하였다.

박세은,백성필,박명자 한국의상디자인학회 2022 한국의상디자인학회지 Vol.24 No.2

The purpose of this study is to analyze the structural properties of 100% wool fabrics knitted with various stitch types and to evaluate dimensional stability from shrinkage in wet cleaning and drying. Materials were weft-knitted from twenty-four different stitches with 7 gauge using a computerized flatbed knitting machine. Weight, thickness, density, and length were measured. A domestic washing machine and a tumble dryer were used for the shrinkage test. The results are as follows: Knitted fabrics were divided into 3 groups based on weight per unit area. Porous knits show light weight whilst milano, pintuck, rib stitches belong to the heaviest group. A positive correlation between weight and thickness was found and the same result was obtained for wale density and weight. Dimensional shrinkage of knitted fabrics was increased during repetitive wet cleaning and drying regardless of knit stitches. Especially, fabrics knitted with float, tuck, cable, and links & links stitches samples were contracted more than 15% in the first treatment whereas 2x1 rib stitch showed 1% shrinkage rate. Fisherman and milano stitches contracted in both course and wale direction with similar shrinkage rates. However, porous knits with float and tuck stitches shrank in course direction by 20% as well as cable samples contracted from 5% to 20% after repeated washing and drying. On the other hand, 30% and 15% contraction of wale direction occurred in orderly float and links & links stitches, respectively. Machine dried knits have a higher shrinkage rate than air-dried knits, but the drying method did not affect to the direction of contraction. In conclusion, variations of knit, tuck, and float stitches affect knit construction and dimensional stability from shrinkage in wet cleaning and drying of wool knitted fabrics.

영지버섯균 발효 꾸지뽕나무 가지 톱밥 추출물의 항염증 활성

박세은,김명곤,김승,Park, Se-Eun,Kim, Myung Kon,Kim, Seung 한국버섯학회 2021 한국버섯학회지 Vol.19 No.3

염증은 외부 자극으로부터 보호하는 중요한 면역반응이다(Jeong et al., 2012). 그러나 NO 및 inflammatory cytokine과 같은 염증 매개 인자의 과도한 생성은 비정상적인 염증 반응을 초래할 수 있다(Paradise et al., 2010). 염증 매개 인자의 생성과 염증 신호 전달을 조절하는 중요한 역할을 하는 대식세포는 LPS 자극에 의해 NF-κB가 활성화 되어 inflammatory cytokine 등의 염증 매개 인자들이 분비가 증가되며 염증 반응을 심화시킨다(Lee et al., 2012). 본 연구에서는 영지버섯균 발효 꾸지뽕나무 가지 톱밥 추출물을 이용하여 LPS로 염증을 유도한 Raw264.7세포에서 염증 관련 인자들의 생성 및 발현에 미치는 영향을 분석하여 항염증 효과를 확인하였다. NO는 염증에서 중요한 역할을 하며 대식세포의 염증 반응 조절 평가시 대표적인 지표로 사용되며 iNOS에 의해 생성이 유도되며 PGE₂는 염증 매개 인자로 inflammatory cytokine 생성에 관여하며 COX-2에 의해 생성이 유도된다(Paradise et al., 2010; Posadas et al., 2000). 발효추출물이 RAW264.7세포에서 세포독성 없이 NO의 생성과 PGE₂의 생성을 감소시켰으며 이 결과는 발효 추출물 처리에 의해 iNOS와 COX-2의 발현이 감소한 것과 일치하였다. 또한 염증 반응을 조절하는 대표적인 inflammatory cytokine으로 알려진 IL-1β, TNF-α의 생성이 감소되었다. 따라서 발효추출물은 NO, PGE₂, inflammatory cytokines 생성을 감소시켜 항염증 효과를 나타낸다고 볼 수 있다. NF-κB는 iNOS, COX-2 및 inflammatory cytokine의 발현을 조절하는 전사인자로 IκB와의 결합에 의해 NF-κB의 핵 내 이동이 억제되며 불활성화상태로 존재한다. LPS 자극에 의해 IκB가 인산화 및 분해되면 NF-κB가 활성화되어 핵 내로 이동하여 염증성 매개인자들의 발현을 유도하고, 염증성 질환 뿐만 아니라 다양한 질환을 유발시키는 것으로 알려져 있다 (Kawai and Akira, 2006; Ghosh and Ksarin, 2002). 본 연구에서는 LPS에 의해 자극된 RAW264.7 세포에서 IκB의 분해 및 NF-κB의 전이가 발효추출물에 의해 감소됨을 확인하였으며 발효추출물에 의한 iNOS, COX-2 및 inflammatory cytokine 감소는 NFκB 활성화 감소에 의해 조절되는 것으로 사료된다. 이러한 결과들을 통해서 발효추출물이 NF-kB 활성화 억제를 통해 염증 매개 인자들의 생성 및 발현을 감소시킴으로서 염증 반응 억제 효과를 나타냄을 확인하여, 염증 관련 질환에 대해 예방 및 개선을 위한 항염증 기능성 소재로 사용될 수 있음을 시사한다. In this study, we evaluated the anti-inflammatory effect of extract from Cudrania tricuspidata twig sawdust fermented with Ganoderma lucidum mycelium. Fermented Cudrania tricuspidata twig sawdust extracted with 70% ethanol and elucidated the potential signaling pathway in lipopolysaccharide (LPS)-induced RAW264.7 cells. Fermented Cudrania tricuspidata twig sawdust inhibits LPS-stimulated nitric oxide (NO) production without affecting cell viability in a dose-dependent manner and production of LPS-induced pro-inflammatory cytokines such as interleukin (IL)-1β, tumor necrosis factor (TNF)-α and prostaglandin2 (PGE₂). Fermented Cudrania tricuspidata twig sawdust also suppressed the expression of the pro-inflammatory mediators such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in LPS-stimulated RAW264.7 cells. Moreover, Fermented Cudrania tricuspidata twig sawdust significantly attenuated LPS-induced IkappaB (IκB) degradation and suppressed nuclear factor kappa B (NF-κB) nuclear translocation. These results suggest that fermented Cudrania tricuspidata twig sawdust may have great potential for the development of anti-inflammatory agent.

포항 영일만 이산화탄소 지중저장 모니터링을 위한 주파수영역 역시간 구조보정 기반 4차원 시간경과 탄성파 기술의 적용성 검토

박세은,김대식,오주원,민동주,김병엽 한국자원공학회 2021 한국자원공학회지 Vol.58 No.5

2013년부터 포항 영일만에서 이산화탄소 지중저장 실증 프로젝트가 시작되었고, 2017년 초 소규모 이산화탄소 주입에 성공하였지만, 같은 해 11월에 발생한 포항지진으로 인해 모니터링 실증단계는 수행되지 않았다. 이 연구에서는 주파수영역 역시간 구조보정을 기반으로 한 4차원 시간경과 탄성파 모니터링 기술의 국내 적용성을 검토하기 위해, 포항 영일만 이산화탄소 지중저장 프로젝트에서 계획했던 모니터링 탐사를 가정한 수치모델링을 통해 인공합성 탐사자료를 획득하였다. 이산화탄소 주입을 총 3차로 가정한 속도 모델에서 획득한 인공합성 모니터링 탐사자료에 주파수영역 역시간 구조보정 기반의 4차원 탄성파 모니터링 기술 적용 결과, 포항 영일만 지중저장 프로젝트에서 40개의 수신기를 이용해 설계되었던 모니터링 시스템을 반영하여 주입 이산화탄소에 의한저장층에서의 진폭 변화 감지가 잘 되는 것을 확인하였다. CO2 geosequestration has been attracting worldwide attention as a solution to reduce greenhouse gas emissions. In South Korea, the Pohang CCS demonstration project started in 2013. Although a small amount of CO2 was successfully injected in early 2017, the demonstration stage for geophysical monitoring could no longer continue because of the Pohang earthquake that occurred in November 2017. In this study, we examine the applicability of 4D seismic time-lapse monitoring technology based on frequency-domain reverse-time migration to synthetic 4D time-lapse seismic data considering monitoring acquisition, which is planned for application in the Pohang CCS demonstration project. Assuming that the velocity drops because of injected CO2 in the three monitoring stages, the amplitude variations caused by injected CO2 are detected well using the planned monitoring system in the Pohang CCS demonstration project.
