우리나라 연안의 평균해면이 증가하고 있다는 주장과 고극조위, 저극조위가 증가(또는 변동)하고 있다는 주장이 제기되고 있으나, 연구자가 사용한 자료의 기간 및 분석 방법 등에 차이가 있고, 결측자료(missing data) 및 이상자료(outlier) 등을 처리한 방법이 서로 차이가 있기 때문에 전체적으로 또는 부분적으로 분석결과가 차이를 보일 수 있다. 또한 추세분석에서는 통계적인 신뢰수준에 대한 검정과정 없이 단순하게 선형회귀곡선식을 이용하여 기울기의 부호만으로 증가 감소를 판단하는 경우도 있다. 그러나 추세분석은 최적의 추세곡선을 찾아내는 것 이전에 추세의 유무를 통계적인 신뢰수준을 기준으로 검정하는 것이 필요하다. 본 연구에서는 추세분석의 필수과정인 추세검정(추세가 있는가? 없는가?)을 Mann-Kendall 방법을 이용하여 우리나라 전 연안 조위관측소의 평균해수면 및 고극조위, 저극조위 자료에 대하여 수행하였다. 추세검정 결과를 다음과 같이 도출할 수 있었다. 평균해수면은 95% 유의수준으로 분석에 포함된 전체 30개 검조소 중 대산, 보령, 군산, 목포, 통영, 거문도, 부산, 가덕도, 제주, 서귀포, 속초, 포항, 울산, 울릉도 지점 등 19개 지점이 추세가 있는 것으로 파악되었으며, 고극조위, 저극조위는 각각 15개, 17개 지점이 추세가 있는 것으로 파악되었다.

Game business has been successfully developed in the world including Korea. Among the many functions, interactivity is the key issue in the state-of-the art gaming system and the success of Nintendo Wii is the example. However, in spite of this success, it is hard to find out the research of the gaming interactivity, for instance what kinds of outcomes are followed by the interactivity. Therefore, the aim of this research tries to disclose the influence of perceived gaming interactivity on various psychological states such as mood, vicarious experience, and vicarious pleasure. The results show that all those factors are influenced by interactivity.

The purpose of this study was to identify the differences in medical care utilization by regional economic status using the National Hospital Discharge Patients Injury Survey. In order to determine economic status of each region, 234 cities and counties were categorized 5 quintiles according to their financial self-reliance ratio. The main results are as follows. First, low economic region has high age-standardized admission rate and standardized mortality rate. Second, of 16 major diseases, cerebrovascular and heart diseases, lung cancer, and stomach cancer reported greater changes in standardized mortality rate by regional economic status. Third, the rate of admission via emergency room in low economic region is higher than that of high economic region. Lastly, in the major illnesses, lower economic status led to an increase in average length of stay. Therefore, In order to bridge the gap in health inequality across regions, a regional medical policy tailored for each region and characteristics of the economic status should be established.

The purpose of this study was to supplement the NURI Curriculum by investigating the practicing level of the NURI Curriculum for 5-year olds according to the demographic backgrounds of early childhood teachers. The subjects of this study were 201 early childhood teachers who work at kindergartens and child care centers located in Gyeonggi Province and were in charge of 5-year olds. The instrument used was a questionnaire measuring the practicing level of the NURI Curriculum. The results of this study were as follows. First, the practicing level of the NURI Curriculum for 5-year olds generally showed high scores. A total average of 3.24 on a 4 scale was found. In each case, educational contents have the highest score, 3.40, and educational evaluation has the lowest score, 3.03. Secondly, teachers' age, teaching career and educational background had an affect on the practicing level of the NURI Curriculum for 5-year olds, but their certificate and institution type did not. That is, the higher the teachers' age, teaching career and educational background, the higher the practicing level of the NURI Curriculum for 5-year olds.

The purpose of this study was to investigate the effects of child care teachers' emotional supports in individual classrooms on children's social skills, including self-control, assertion, cooperation, and responsibility that were related to their character development. Data were collected in a purposive sample involving 32 teachers working with 646 children at age five and 555 parents of the children. Hierarchical Linear Modeling (HLM) was used to analyze a two-level model. The results showed that there were significant differences among classes with data reported by teachers but characteristics such as teachers' education and work experiences, child-teacher ratio, and type of child care centers as well as teacher's emotional supports did not explain the differences. Children's age and gender, which were predictors at the individual level, significantly explained their level of social skills reported by parents as well as teachers. The findings implied that other predictors influencing differences among classes should be explored in future studies.

This study was conducted to examine the dry matter production and leaf photosynthesis under different fertilizer application in Yacon(Polymnia sonchifolia)plants. Under field conditions, dry matter production of stable mature application plot(S-1) was much larger than non-treated control plot(CTL), but bulb dry weight of 10kg nitrogen application plot per 10a (N-10) was not differentiated from CTL. The maximum photosynthetic rates increased in Yacon plants grown at S-1 while in the rates of CTL reduced under glasshouse in the same treated pot condition. The optimum temperature for the highly photosynthetic rates is about $34{\pm}3^{\circ}C$, and the rates did decrease by stomatal resistance below 28℃. The estimated light saturation point was $1200{\mu}mol{\cdot}m^{-2}s^1$. The results of this study indicate that soil conditions were highly related to dry matter production and leaf photosynthesis rate in Yacon plants.
