This study analyzed characteristics of ozone (O₃) formation regimes in Busan over a period of recent five years (2015~2019) and compared the findings with those obtained in Seoul. We employed four observed variations: early morning commuting-hour (i.e., 06:00-09:00 LST) nitrogen dioxide (NO₂), peak-hour (i.e., 12:00-16:00 LST) O₃, 8-hour average O₃ (MDA8 O₃), and △O₃ (=O_{3_max}- O_{3_min}) in Busan and Seoul. In addition, the NO₂-O₃ relation was assessed to interpret which of NOx-limited or volatile organic compound (VOC)-limited was dominant. In Busan, the annual mean O₃ concentration was relatively higher than in Seoul, whereas there were fewer high-concentration days. The Pearson correlation coefficients (R) between Early morning-hour NO₂ and the Peak-hour O₃ was positive (but close to zero) in Busan and negative in Seoul. Likewise, the R between the Early morning-hour NO₂ and the △O₃ showed a relatively considerable positive correlation (R=+0.4~0.5)(R=+0.4~0.5) in Busan, while a weak positive correlation (R=+0.1~0.2) in Seoul. From this result, it can be inferred that the O₃ formation regime in Busan was intrepreted to be nearly neutral or relatively closer to the NO_x-limited regime than Seoul, while Seoul to the VOC-limited regime. The study findings imply that O₃ control strategies should be applied differently in Busan and Seoul. The results here were inferred from surface NO₂ and O₃ observations, and the varification studies based on in-situ VOCs measurements would be needed.

In the Oriental Western Consideration of Habitual Abortion, the result of this study is summarized as follows: 1. Habitual abortion means repetition of Tatae(abortion within 3 months), Sosan(abortion after 3 months), and Bansan(abortion after 5 months), as it agrees with Hoaltae, Sutatae and Nuing-Nuta in oriental medical science. 2. Frequency in Occurrence of habitual abortion is about 0.2-0.4%> in the whole pregnancy and the Ratio of Risk increases according to frequency and age increase. 3. Generally, the cause of habitual abortion is due to the cause of the mother. Therefore, diagnosis and treatment of before-childbirth are needed, and 'measures taken to prevent abortion' is in use to improve the condition of health of before-childbirth in oriental medical science. 4. The 50-60% of early abortion is due to the heterochromosome and the ratio of risk of habirual abortion is hightest in heterochromosome. 5. The causes of habitual abortion are summarized as vital energe and blood weakness. impairment of Chong and Ren, aflection by exopathogen, fever caused by blood deficiency. weakness of the spleen and the stomach, excess of seven emotion. excess of a sexual desire and injury of a contusion and also the treatments are summarized as invigorating qi (vital energy) and enriching the blood, reducing fever and enriching the blood, reinforcing the spleen, tonifying the Chong and Ren, the practice of a sceticism, psychological peace in oriental medical science. 6. The approch of modem oriental medical science is based on diagnosis and treatment based on 'over all analysis of symptoms and signs' of traditional oriental medical science. it goes abreast with diagnosis of western medical science, and it can be expected mare inclusive effect of treatment because 'Acupuncture for prevent abortion', 'Acupuncture with the needle warmed by burning moxa', and so on being developed except medicinal therapy.

Computing Technology implementation suggests a dramatic change in work or organizational environment. The study aims to examine how IT adoption affected employees' attitudes toward jobs and behaviors toward customers in restaurant operations. The employee attitudinal variables examined in the study included employees' perceptions on internal work motivation, general job satisfaction, and pride in organization, while positive employee behaviors were used to examine employees' behavioral changes induced by IT implementation. The study sampled employees of full-service and mid-scale restaurants. To test the relationships among the employees of full-service and variables proposed in the research model changed by the IT implementation, six hypotheses were proposed. This study is meaningful in making a progress in finding a support for a link between task perceptions and attitudes in organizational environment change. The practical contribution of this research lies in for restaurant owners or managers to obtain a better perspective of the technology adoption and implementation decisions. 컴퓨팅 테그놀로지 도입은 직장이나 조직내에서 커다란 변화를 가져온다고 한다. 이 연구는 레스토랑 내에서의 IT도입이 종사자들의 직업에 대한 태도와 고객에 대한 행동에 미치는 영향을 파악하는 것을 목적으로 한다. 이 연구에서 IT 도입에 따른 종사자들의 태도를 측정하는 변수는 IT 도입에 대한 인식, 내적 동기 부여, 전반적인 직업의 만족도, 조직에 대한 긍지이며, 종사자들의 행동 변수로는 고객에 대한 긍정적인 행동이 사용되었다. 이 연구의 표본은 full-service, mid-scale의 레스토랑에 종사하는 종업원들이다. 제안된 연구 모형에 포함된, IT 도입에 따른 종사자들의 태도와 행동의 변화를 조사하기 위하여 6개의 가설이 수립되었다. 이 연구는 조직 환경의 변화에 따른 직무에 대한 인식과 태도의 연관성에 대한 지식을 발전시킨다는 면에서 의미가 있다. 이 연구의 산업계에 대한 실증적인 공헌은 레스토랑 owner나 manager에게 컴퓨터 기술 도입에 대한 결정을 하는데 유용한 시사점을 줄 수 있다는 것이다.

백승희,이상원,Baek, Seung-Hee,Lee, Sang-Won Korean Acsdemic Society of Customer Relationship M 2011 CRM연구 Vol.4 No.2

소셜네트워크(Social Network)는 전세계 사용자간의 커뮤니케이션을 지원함으로써 이용자들간의 관계형성을 통해 다양한 정보의 흐름을 유도하고 있다. 이를 통해 사용자는 다양한 혜택을 누리고 있으며 이는 우리사회에 커다란 영향력을 미치고 있다. 본 연구의 목적은 소셜네트워크 서비스(SNS) 이용자의 SNS 이용 심리 및 태도를 Davis의 기술수용모델(TAM)에 근거하여 연구하고자 한다. SNS 이용자들은 개인의 관심분야와 관련하여 다양한 정보를 생산하고, 확산하고, 획득하는 채널로서 SNS를 활용하고 있으며 이러한 활동에 따른 SNS 이용혜택이 소비자의 지각된 유용성에 어떻게 영향을 미치는지에 중점을 두고 살펴보고자 한다. 본 연구의 SNS 이용자 혜택은 SNS의 다양한 혜택 중에서도 이용자들 간의 상호작용을 통해 형성되는 관계혜택에 초점을 두고 있으며 이러한 소비자의 관계혜택 중 소비자가 느끼는 심리적 혜택과 정보적 혜택은 SNS이용자의 관여도에 따라 지각된 유용성이 다르게 영향을 미칠 것이라는 가정 하에 이와 관련한 지각된 유용성과 지각된 용이성이 브랜드 태도에 어떻게 연결되는지를 살펴보고자 한다. Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

백승희(Seung-Hee Baek) 대한검안학회 2017 Annals of optometry and contact lens Vol.16 No.2

Myopia is the most common refractive error throughout the world and the prevalence of myopia demonstrates regional and ethnic differences. Korea has as high prevalence of myopia as those in other developed Asian countries. The prevalence of myopia is much higher in adolescents and young adults compared to the other age groups, and have been increasing in recent decades. The Korean Ophthalmological Society has participated in the Korea National Health and Nutrition Examination Survey (KNHANES) since July 2008 and has conducted nationwide epidemiological survey with the purpose of elucidating the prevalence of common eye disorders including refractive errors. The epidemiology of refractive errors in Korean population from KNHANES 2008-2012 was reported on behalf of the Epidemiologic Survey Committee of the Korean Ophthalmological Society recently. The nationwide prevalence of myopia from the KNHANES data was reviewed and compared with other previous studies to evaluate changes of myopia prevalence in different age groups of the Korean Population.

한국인의 근시와 위험인자 : 국내 역학연구에 관한 고찰

백승희(Seung-Hee Baek) 대한검안학회 2017 Annals of optometry and contact lens Vol.16 No.3

Myopia is the most common refractive error throughout the world and the prevalence of myopia demonstrates regional and ethnic differences. Numerous studies have reported the association of myopia with risk factors including young age, urban residence, high educational level of subjects or of their parents, or high income. However, association of one specific risk factor with myopia is not always consistent in published studies and multivariate analyses report different associations according to the variables that were included. The Korean Ophthalmological Society has participated in the Korea National Health and Nutrition Examination Survey (KNHANES) since July 2008 and has conducted nationwide epidemiological survey. The epidemiology of refractive errors in Korean population from KNHANES 2008-2012 was reported on behalf of the Epidemiologic Survey Committee of the Korean Ophthalmological Society recently. The nationwide prevalence of myopia from the KNHANES data demonstrated biphasic distribution by age; Myopia prevalence in Korean population increased as age increased from childhood to young adulthood with the highest prevalence in adolescents and young adults aged between 12 and 29 years. The prevalence then showed decreasing pattern as age increased in adult age groups with the exception of a small increase in the oldest age group of 70 years or older. Studies based on KNHANES data demonstrated various associations of myopia with urban residence, female gender, education, and other risk factors in various age groups. Risk factors of myopia in the Korean population are discussed with possible differential association of myopia with certain risk factors in different age groups.

군 급식 제공 메뉴 분석에 의한 식사의 질 평가

백승희 ( Seung Hee Baek ),김수연 ( Soo Yeon Kim ) 한국식품영양학회 2010 韓國食品營養學會誌 Vol.23 No.4

This study attempted to estimate the dietary quality and the food diversity by analyzing the military foodservice menu. To evaluate the dietary quality, an analysis of NAR(Nutrient Adequacy Ratio) and MAR(Mean Adequacy Ratio) were carried out. DDS(Dietary Diversity Score), DVS(Dietary Variety Score) and DMGFV(Dairy Product, Meat, grain, Fruit, Vegetable group) were used for assessment of food diversity. A Can-pro 3.0 and an excel were used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. The results were as follows. The NAR of the 9 nutrients was above the RDAs and MAR was 1.71±0.19. For 19 days(61.3%), DDS was 5 and for 12 days(38.7%), DDS was 4. The average of DDS was 4.6±0.25. The Fruit & vegetable groups were not often served compared to other groups and especially fresh fruit were not given enough. The average of DVS and DVSS were 22.48±0.61 and 29.26±0.66 each. The most frequent food pattern was ``DMGFV=11111`` which was served for 19 days(61.3%) and second frequent pattern ``DMGFV=11101`` was served for 12 days(38.7%). DDS was significantly associated with Vit. C intake and DVS and DVSS was significantly related to Vit. B1 and Vit. B2 intakes. The MAR was significantly correlated with only DVSS. It could be interpreted that DVSS is a useful parameter for evaluating nutrient intakes as previous studies verified. Based on these findings, it can be said that military foodservice was provided with adequate nutrition and diversity. Menu was well composed of various foods which met the nutrition standards, but should provide more fresh fruits for adequate provision of vitamins and minerals.
