  • Purpose - This is longitudinal research which aims to investigate the meaning of greenness to consumers' behavior. Consumers adopt green marketing as a new factor in product buying and consumption and more and more consumers prefer green product and services. Consumers' green buying behavior can be different from other purchasing experiences. There would be changes in the meaning of green as time passed and it can be different from countries to other countries. This study examines focus group studies with several groups. There is a ten-year gap between 2010 focus group and 2019 focus group interviews. With this ten-year gap, we can find the change of greenness to consumers. Research design, data, and methodology - The data were collected from Turkish, Korean, Kazakhstan people. This is a cross-sectional study and focus group interview was designed. We can gain information relevant to the research problem with using focus group study and get some insights into basic needs and attitudes of green marketing. The subjects for green purchase interviewee were confined to under 40 years old's shoppers regardless of gender. The first study was investigated with several groups in 2010 and the second interview were conducted in 2019. Results - Results show that the meaning of greenness for consumer has changed over time in accordance with the growing accordance of environmental sustainability. Basically, green marketing still means valuable, natural, recycle-able, good for health, clean, smart behavior, essential benefit. The concept of greenness significantly evolved since it was investigated in 2010. It moves away from focusing on specific environmental issues to considering global sustainability issues. Especially we found that greenness can be related with globalization, higher education, social status at the 2019 interview. Conclusions - This paper attempted to confirm the green marketing is essential and expands its meaning to various aspect. Usually, we can think green marketing is everywhere, therefore, people don't care about green issues in real. But consumers are adopting green marketing more and more, it can be a means to attract potential consumers. Therefore, companies should provide enough greenness information for people and they might apply greenness communication to attract potential customers.

  • Objective: The purpose of this study was to examine the bidirectional relation between mobile phone dependency (MPD) and self-regulated learning (SRL) of early Korean adolescents in $4^{th}$, $6^{th}$ and $8^{th}$ grade, while taking into account gender differences. Methods: The study made use of panel data from the Korean Children and Youth Panel Study (KCYPS), and three waves of data collected from 2,264 adolescents were analyzed by means of autoregressive cross-lagged modeling. Results: The results can be summarized as follows. Firstly, MPD and SRL were consistently stable for adolescents in $4^{th}$, $6^{th}$ to $8^{th}$ grades. Secondly, a bidirectional relations between MPD and SRL were confirmed. In other words, there was a significant influence of a high level of MPD on a subsequent low level of SRL, and the high level of SRL also had a significant effect on the lower level of MPD across time. According to multi-group analysis, no gender differences were found in the relations between two constructs during the studied period. Conclusion: Findings highlighted not only the necessary media usage education but also parenting intervention strategies may help early adolescents to be prevented from negative effects of media usage and to enhance self-regulated learning ability. Based on the results, more implications were also discussed.

  • Objective: To investigate the dental phenotypes and treatment modalities (Tx-Mod) in Korean patients with Parry-Romberg syndrome (PRS) using longitudinal data. Methods: The samples consisted of 10 PRS patients, who were treated and/or followed-up at Seoul National University Dental Hospital between 1998 and 2019. Using a novel PRS severity index based on the numbers of the atrophy-involved area and asymmetry-involved item, we classified them into mild (n = 3), moderate (n = 2), and severe (n = 5). Dental phenotypes, including congenitally missing tooth (Con-Missing-Tooth), microdontia, tooth with short root (Short-Root), tooth with dilacerated root, and delayed eruption/impacted tooth, were investigated along with Tx-Mod. Results: The side of occurrence of all dental phenotypes showed 100% concordance with the side of PRS involvement. The most two common dental phenotypes were Con-Missing-Tooth and Short-Root (n = 29 and n = 17 in six patients). The sums of the average number of Con-Missing-Tooth and Short-Root increased from mild PRS to moderate PRS and severe PRS cases (1.0, 6.0, and 6.2). In terms of Tx-Mod, growth observation due to mild atrophy, fixed orthodontic treatment, and grafting were used for mild PRS cases. Tx-Mod for moderate PRS cases involved growth observation for surgery due to an early age at the initial visit. For severe PRS cases, diverse Tx-Mod combinations including unilateral functional appliance, fixed orthodontic treatment, growth observation, grafting, and orthognathic surgery were used. Conclusions: The novel PRS severity index may be useful to provide primary data for individualized diagnosis and treatment planning for PRS patients.

  • With the prosperous economy, the status of diet and nutrition among the urban and rural Chinese population has been improved significantly. This paper will focuses on three main surveys in China. (1)'Food and Nutrition Surveillance System in China': Phase I focused on analysis of previous data. Phase II was a pilot survey initiated in Beijing, Hebei, Heilongjiang, Ningxia, Zhejiang, Guangzhou, and Sichuan in 1990. (2) 'The China Health and Nutrition Survey' is an ongoing longitudinal project covered 8(9) provinces in 1991,1993,1997,2000. This paper will analysis the adults aged 18 45 of 1991, 1993, 1997, and 2000. (3) Survey on the status of nutrition and health of the Chinese (2002) is an across sectional study covered 31 provinces, autonomous region and the municipalities. The data was used to analyze the status of food consumption and dietary nutrients intake of Chinese population. In the past ten years, the prevalence of malnutrition and nutrition deficiency has been continuously decreased. The consumptions of animal products, milk, and edible oil have been increased, while the dairy and legume products consumption decreased. The unbalance was showed with a downward trend in cereals, vegetables and fruits consumption and a significant increase in animal products and oil intake among urban people. Dietary pattern of some subjects went away to 'high energy density' diet. The deficiency of calcium, retinal and ascorbic acid etc, especially in the rural areas still exist. China is undergoing a remarkable, but undesirable, rapid transition towards a stage of the nutrition transition characterized by high rates of DR NCDs in a very short time. China is facing the dual challenges of nutrition deficiency and nutrition imbalance. The results can help to understand the dietary structure and the status of nutrition among Chinese people over the past years. It will provide the basis for formulating relevant state policies.

  • Objectives: This study aimed to examine the association between preschool education experiences and adulthood self-rated health using representative data from a national population-based survey. Methods: Data from the Korean Labor and Income Panel Study in 2006 and 2012 were used. A total of 2391 men and women 21-41 years of age were analyzed. Log-binomial regression analyses were conducted to examine the associations between preschool education experience and self-rated health in adulthood. Parental socioeconomic position (SEP) indicators were considered as confounders of the association between preschool education experience and adulthood subjective health, while current SEP indicators were analyzed as mediators. Age-adjusted prevalence ratios (PRs) and the associated 95% confidence intervals (CIs) were estimated. Results: Compared with men without any experience of preschool education, those with both kindergarten and other preschool education experiences showed a lower prevalence of self-rated poor health (PR, 0.65; 95% CI, 0.47 to 0.89). In women, however, such an association was not evident. The relationship of preschool education experiences with self-rated poor health in adulthood among men was confounded by parental SEP indicators and was also mediated by current SEP indicators. After adjustment for parental and current SEP indicators, the magnitude of the associations between preschool education experiences and adulthood subjective health was attenuated in men. Conclusions: Preschool education experience was associated with adulthood self-rated health in men. However, this association was explained by parental and current SEP indicators. Further investigations employing a larger sample size and objective health outcomes are warranted in the future.

  • 현재 우리나라에서 수집가능한 데이타를 이용하여 간단한 수질예측 모델의 작성을 목적으로서, 우리나라의 주요한 12개 댐호(湖)를 대상으로 유역정보와 호수 수질과의 관계를 조사하였다. 얻어진 결과는 다음과 같다. 1. 호수의 환경정보가 매우 적기 때문에 데이타의 취사선택에 관해서 충분한 검토를 행하기 어려운 점이 있어서 앞으로 이들 데이타의 확보나 정보의 정비가 필요하다고 판단된다. 2. 댐호(湖)의 영양염 농도의 예측에는 침강속도를 0.4m/년으로서 Dillon과 Kirchner식을 이용하는 것이 좋았다. 3. 엽록소 a의 농도는 엽록소 $a=395\;{\time}\;Nu-1.090$의 식으로 예측할 수 있었다. 4. 앞으로 예측의 정도를 향상시키기 위해서는 발생원단위 및 배출원단위의 검토와 보다 많은 호수나 댐에서의 실측 데이타 및 유역 환경 데이타의 축적 및 정비가 필요하다고 판단된다.

  • Objectives : There is a paucity of data on the long-term course of obsessive-compulsive disorder (OCD) and chronological relationship between OC symptoms and their related symptoms such as anxiety and depression. The purpose of this study was to investigate the longitudinal course of OC symptoms as well as anxiety and depression which are believed to be associated with OC symptoms. Methods : Data for 155 patients with OCD who completed general evaluation for OCD were used. Forty four were excluded to minimize the effect of the different age of onset on the clinical course. One hundred eleven patients finally participated in the analysis. Cross-sectional correlations between each symptom as well as between such symptoms and the duration of illness were analyzed. Further correlation analysis was done within two groups that were divided by 7 years of the duration of illness. Results : There were significant correlations not only between the severity of OC symptoms and anxiety but also between anxiety and depressive symptom, regardless of the duration of illness. These correlations between such symptoms were also found within patients with the duration of illness below 7 years, whereas these were not within the group with the duration of illness above 8 years. Conclusion : Patients with OCD in this study shows the moderate to severe level of OC symptoms irrespective of the duration of illness. Our finding also suggests that the OC symptoms, especially obsessions are closely related to anxiety and depressive symptoms and these relationships might be pronounced in relatively early phase of the OCD after onset.

  • A remarkable sea surface cooling (SSC) event was observed in the eastern sea of Korean peninsula based on new generation sea surface temperature (NGSST) satellite images in September 2005, when typhoon Nabi passed over the East Sea. The degree of SSC ranged from $1^{\circ}C\;to\;4^{\circ}C$, and its maximum was observed in the southeastern sea area. Daily variations in sea surface temperature at a longitudinal line $(35^{\circ}-41^{\circ}N,\;132^{\circ}E)$, derived from satellite data for September 1-13, 2005, showed that the SSC lasted about 3 days after the typhoon passed in the south of $39^{\circ}N$, whereas it was unclear in the north of$39^{\circ}N$. Water temperature measured by a mooring buoy suggested that the SSC was caused mainly by a vertical mixing of the water column driven by the typhoon, rather than by coastal upwelling.

  • 본 논문은 과잉간섭 양육방식이 휴대전화의존도에 미치는 영향에서 우울의 매개효과를 살펴보고자 했다. 연구를 위해 한국아동 청소년 패널조사(Korean Children and Youth Panel Survey, KCYPS) 2015년 초등학교 4학년 패널 5차년도 자료를 활용하였다. 자료는 AMOS를 이용하여 구조방정식 모델을 분석하였고, 매개효과의 유의성은 AMOS의 bootstrapping 검증으로 실행하였다. 연구결과의 내용은 다음과 같다. 첫째, 과잉간섭 양육방식과 우울, 우울과 휴대전화의존도, 과잉간섭 양육방식과 휴대전화의존도의 경로를 검증한 결과 유의미한 것으로 나타났다. 둘째, 과잉간섭 양육방식이 휴대전화의존도에 미치는 영향에 대한 우울의 매개효과를 성별, 지역, 교급을 통제한 상황에서 검증한 결과, 우울의 매개효과가 유의미한 것으로 검증되었다. 이러한 연구결과는 아동이 휴대전화에 의존되는 과정에 부모의 과잉간섭 양육방식이 중요한 원인 변인으로 작용함을 인지해야 하고, 부모의 과잉간섭 양육방식으로 인한 아동의 우울감정을 휴대전화의존 전 단계에서 부터 다루어야 하는 중요 변인이라는 것을 시사한다. 또한 가정환경, 가족관계는 휴대전화 예방 뿐 아니라 아동이 독립된 성인으로 건강하게 성장하기 위해 기본 근간이 되는 바탕이 됨을 인지해야 한다는 것을 시사한다. 본 연구결과를 바탕으로 부모로부터 과잉간섭 양육방식을 받은 아동의 휴대전화의존도 문제에 대한 개입을 위한 실천적 논의가 진행되었다.
