정서영,안병덕,홍소이,공은경,마연주,정영정 大韓小兒齒科學會 2011 大韓小兒齒科學會誌 Vol.38 No.1

미성숙 영구 전치에서 MTA를 이용한 치근단 형성술의 예후를 평가하기 위해, 영구 전치의 외상으로 MTA를 이용한 치근 단 형성술을 받은 환자 중 최소 3개월 이상의 경과 관찰이 시행된 환자 49명, 치아 64개의 의무기록과 방사선 사진을 검토하 였다. 환자 정보, 치아 및 치주조직 외상 위치와 유형, 치료 전 치근단 병소 유무, 임상 증상 유무, MTA 충전 상태, 치근단 형 성술 이후 치근단 병소 치유 및 치근단 경조직 장벽 형성 여부를 조사하고, 임상적, 방사선학적 성공을 평가하여 다음과 같은 결과를 얻었다. 1. 64개의 미성숙 영구전치에 시행된 MTA를 이용한 1-visit 치근단 형성술은 89.1%의 임상적 성공률과 73.4%의 방사 선학적 성공률을 보였다. 2. 상악 치아와 하악 치아에 행해진 MTA를 이용한 1-visit 치근단 형성술 비교시 상악에서 유의하게 더 높은 성공률을 보 였다. 3. 치아 외상 및 치주조직 외상 유형에 따른 성공률은 유의한 차이를 보이지 않았다. 4. MTA의 적절한 충전 여부는 성공률에 영향을 미치지 않았다. The aim of this study was to assess the outcome of MTA apexification in young permanent anterior teeth. Among the patients with the traumatized permanent incisors which were treated with MTA apexification, the dental records and radiographs were examined only for the patient who had follow-up examination at least 3 months after the treatment. Forty nine patients with 64 teeth were included in this study. Demographic information, location and type of teeth and periodontal injury, pre-treatment periapical lesion, clinical symptoms, status of MTA filling, healing of apical lesion and apical barrier formation after treatment were investigated. The outcome based on clinical and radiographic criteria were assessed. The results were as follows 1. Of 64 immature permanent incisors with MTA apexification, the clinical and radiographic success rates were 89.1% and 73.4%, respectively. 2. The maxillary incisors showed significantly higher success rates than the mandibular incisors. 3. There was no statistically significant difference in success rates among the teeth with different types of teeth and periodontal injury. 4. The status of MTA filling did not influence the clinical and radiographic success.

정서영,송미경 한국건강심리학회 2017 한국심리학회지 건강 Vol.22 No.1

The purpose of this study was to verify the mediating effects of intolerance of uncertainty and emotional clarity in the relationship between daily stress and internet addiction in university students. Therefore, 250 university students were asked to complete a series of questionnaires consisting of Life Stress Scale for College Students, Internet Addiction Proneness Scale for Adults(A-Scale), Intolerance of Uncertainty Scale(IUS) and Trait Meta-Mood Scale(TMMS). The following results were obtained; First, daily stress showed a significant positive correlation with internet addiction and intolerance of uncertainty, and a significant negative correlation with emotional clarity. Further, internet addiction showed a significant positive correlation with intolerance of uncertainty, and a significant negative correlation with emotional clarity. Second, intolerance of uncertainty partly mediated the relationship between daily stress and internet addiction. Finally, emotional clarity partly mediated the relationship between daily stress and internet addiction. Based on these results, programs can be developed for internet addiction prevention and care for university students. Recommendations for future research were provided. 본 연구에서는 대학생의 생활스트레스와 인터넷 중독의 관계를 불확실성에 대한 인내력 부족과정서인식 명확성이 매개하는지 검증하고자 하였다. 이를 위해 남녀 대학생 250명을 대상으로 생활스트레스척도, 성인 인터넷 중독 척도, 불확실성에 대한 인내력 부족 척도, 정서인식 명확성 척도를 실시하였다. 분석 결과, 첫째, 생활스트레스와 인터넷 중독, 불확실성에 대한 인내력 부족 간에는 유의한 정적 상관을 보인 반면, 생활스트레스와 정서인식 명확성 간에는 유의한 부적 상관이 나타났다. 인터넷 중독과 불확실성에 대한 인내력 부족 간에는 유의한 정적 상관을 나타낸 반면, 생활스트레스와 정서인식 명확성 간에는 유의한 부적 상관이 나타났다. 둘째, 생활스트레스와인터넷 중독의 관계를 불확실성에 대한 인내력 부족이 부분매개하는 것으로 나타났다. 셋째, 생활스트레스와 인터넷 중독의 관계를 정서인식 명확성이 부분매개하는 것으로 나타났다. 이와 같은결과를 바탕으로 대학생의 인터넷 중독 예방과 치료를 위한 개입방안에 대해 논의하고 후속연구를 위한 제언을 제시하였다.

정서영,박영일,이태남,정은경,주나미 한국식품조리과학회 2017 한국식품조리과학회지 Vol.33 No.6

Purpose: This study analyzed the quality properties of cookies made with sea tangle powder in order to improve bowel movements in pregnant women. Methods: To identify the optimal sensory mixing ratio using response surface analysis of sea tangle cookies with sea tangle powder and sugar as independent variables and following a central composite design, which is required for optimizing manufacturing conditions. Results: Based on the results of modeling experimental results and verification of significance, a linear model was selected for color (brightness, redness, yellowness) and moisture content, a 2FI model was selected for hardness and a quadratic model was selected for spreadability. Sea tangle powder was the most significant variable affecting brightness, redness, and yellowness among the mechanical characteristics of cookies. These characteristics were inversely correlated with the amount of sea tangle powder added (p<0.01). Hardness was positively correlated with the amount of sugar (p<0.05), and spreadability was also positively correlated with the amount of sea tangle powder (p<0.05). The test results for the sensory characteristics of cookies made with sea tangle powder showed that the amount of sea tangle powder increased color, smell, flavor, texture, and overall preferences with positive correlations.However, these properties began to decrease at a certain point, where additional sea tangle powder made cookies worse in terms of smell (p<0.01), flavor (p<0.05), and overall quality (p<0.05). Conclusion: Taken together, the optimal mixing ratio for cookies made with sea tangle powder was 5.80 g of sea tangle and 50.71 g of sugar. This study suggests that cookies made with sea tangle powder are effective in relieving constipation in pregnant women.

Sous-vide 조리법을 적용한 감자조림의 품질특성 및 최적화

정서영,주나미 한국식품조리과학회 2018 한국식품조리과학회지 Vol.34 No.6

Purpose: This study evaluated and compared sensory qualities of potatoes cooked using the sous-vide method rather than traditional cooking methods to provide the basic information needed for sous-vide cooking. Experiments were designed with two independent variables, time and temperature. Methods: Response surface analysis was performed to evaluate sensory characteristics of cooked potatoes, and the optimal cooking condition was derived. Results: Based on modelling of the experimental data and significance tests, a linear model was chosen for modeling color (lightness, redness and yellowness), hardness and sweetness among mechanical characteristics, while a quadratic model was used for weight loss and moisture content and a 2FI model was used for salinity. Lightness (p<0.0001), redness (p<0.05) and yellowness (p<0.001) decreased significantly with increasing cooking time and temperature, with temperature having the greatest influence. The hardness of potatoes decreased significantly and inversely with temperature (p<0.01), while sweetness (p<0.05) and salinity (p<0.001) increased significantly, demonstrating the significant effects of cooking temperature. Analysis of the sensory characteristics of potatoes cooked using the sous-vide method revealed a linear model for color, a 2FI model for flavor and a quadratic model for texture, appearance and overall preference. Among sensorial variables, color showed significant differences among cooking conditions (p<0.05), while flavor did not (p<0.5). Texture, appearance and overall preference also exhibited significant differences (p<0.05) and significantly high reliability (R2 0.948, 0.9224 and 0.9404), indicating the adequacy of the chosen models. Of the two independent variables, cooking temperature had more significant effects on color, texture, appearance, and overall preference among sensory characteristics, showing a positive correlation with the last three variables. However, the correlation declined when the temperature reached at a certain point. Conclusion: Taken together, when the sous-vide method was used, the optimal condition for acceptable sensory quality of potatoes was found to be a temperature around 88°C and a time of about 45 min per 100 g of potatoes.

건설사업관리자의 품질관리 직무 역량에 영향을 미치는 요인 분석

정서영,유정호,Jung, Seoyoung,Yu, Jungho 한국건설관리학회 2017 한국건설관리학회 논문집 Vol.18 No.1

오늘 날, 미국과 유럽의 선진 조직에서는 역량의 개념을 인사관리의 기초 정보로 활용하고 있다. 한국의 경우에도 최근에들어 인사관리에 직무역량의 개념이 도입되어, 많은 조직에서는 이에 따라 인력을 관리하고자 하는 추세이다. 하지만, 이러한 추세에도 불구하고 국내에 도입되어 있는 건설사업관리자의 인적자원관리 방식은 경력, 학위, 자격증 등의 요건을 충족하면 능력있는 기술자로 평가받는 연공서열주의의 잔재가 많이 남아있다. 이는 해당 업무에 대한 실질적인 전문성 및 직무역량에 대한 평가정보는 포함되어 있지 않다. 한편, 건설사업관리자의 업무는 사업진행 단계 및 관리업무의 종류에 따라 그 전문성 및 역량이 세분화되어 있으나, 현재의 경력관리 방식으로는 이러한 세분화된 역량의 확인이 어렵다. 그러므로 발주자의 요구 및 프로젝트 특성에 적합한 건설사업관리자를 선택하고, 건설사업관리자가 자신의 직무역량을 실질적으로 관리하기 위해서는 업무별로 세분화된 역량관리 시스템의 구축이 필요하다. 따라서, 본 연구에서는 건설사업관리자의 업무별로 세분화된 역량관리 시스템 구축을 위한 기초연구로서 현행 건설사업관리자의 능력평가 방식을 분석하여 문제점을 제시한 후, 건설사업관리 직무 역량에 실질적으로 영향을 미치는 요인을 통계적으로 분석하고자 한다. Today, the United States, Europe and other advanced organizations are utilizing the concept of competency-based HR management. Recently, many organizations in Korea are also managing workforces by introducing the concept of job competencies in personnel management. However, in spite of the current trend, domestic human resources management methods for construction managers continues to operate by asking about work experience, licensing, education level, etc. This is a seniority system and it functions separately from an assessment of practical job competencies for the business. Moreover, construction management work has been very fragmented in terms of expertise and capacity depending on the type of management work and project progress. Therefore, it is necessary to develop a competencies management system for each business segment to effectively manage job competencies that reflect the the characteristics of a construction manager' s work. As such, the aim of this study is to analyze human resources management methods pertaining to domestic construction managers and present challenges and limitations in current practices. In particular, factors affecting the job competencies of construction managers are analyzed statistically. The results of this study will be used as the basis for future research into development of a construction manager competency management system.
