This study was carried out to develop volume equations for Camellia japonica trees in JejuExperimental Forests using the five commonly used volume models. A total of 200 trees weremeasured in the three experimental forests of Jeju, namely Hannam, Seogwipo and Gotjawalforests. The collected data were divided into two dataset. The majority(80%) of the dataset wereused in the initial modeling while the remaining dataset(20%) were used for validation of thecandidate models. To evaluate these models, coefficient of determination(R2), root mean squareerror(RMSE), mean difference(MD), absolute mean difference(AMD), and coefficient ofvariation(CV%) were used as evaluation statistics. In the model validation, the MD in eachdiameter class were determine for the five models. The two dataset were then combined for thefinal model development. The R2 ranged from 0.7571 to 0.9381 with V=aDbHc having thehighest value. For the RMSE, V=aD2H had the highest with 0.0326, whereas V=aDbHc hadthe best with 0.0258. V=a+bD2H had the best MD with zero(0), whereas V=aDbHc had thehighest with 0.0012. On the other hand, V=D2/(a+b/H) had the best AMD with 0.0186,whereas V=aD2H had the highest. The CV(%) of V=aDbHc was the best with 30.4348. Overall, results of the model evaluation and validation showed that V=aDbHc having DBH andtotal height as predicting variables was considered best based on the rank analysis whileV=aD2H had the poorest performance among the candidate models. 본 연구는 동백나무의 간재적 추정식을 개발하고자 하였다. 제주지역에 자생하고 있는 동백나무 200본을 표준목으로 선정하여 분석 자료로 사용하였다. 재적모델 개발을 위해 80% 자료와 모델 타당성 검정(Validation)을 위해 20% 자료를 무작위로(Randomly) 구분하여 분석하였고, 본 연구에서 제시된 최종모형의 추정된 계수는 100% 자료를 이용하였다. 동백나무에 대한 재적 모델의 적합성 검정은 결정계수(R2), 추정치의 오차(RMSE), 평균편의(MD), 절대평균편의(AMD)와 직경급별 평균편의(MD), 변동계수(CV%)를 비교 분석하였다. 본 연구 결과, 결정계수는 0.7571에서 0.9381로 나타났으며, V=aDbHc에서 결정계수가 가장 높은 것으로 나타났다. 추정치의 오차는 0.0326으로 V=aD2H에서 가장 높았으며, 반면에 0.0258로 V=aDbHc에서 가장 낮았다. 평균편의는 V=a+bD2H에서 0에 값으로 나타났으며, V=aDbHc에서 0.0012로 나타났다. 절대평균편의는 V=D2/(a+b/H)에서 0.0186으로 가장 낮았고, 0.0223으로 V=aD2H에서 가장 높게 나타났다. 변동계수는 V=aDbHc에서 30.4348로 가장 적합한 계수로 나타났다. 5개의 모델식 중 최적의 식은 V=aDbHc에서 나타났으며 V=aD2H에서 적합성이 가장 낮은 것으로 나타났다.

This comparative survey research was conducted to compare the relationship between health promotion lifestyles, self-esteem, health locus of control and health perception for employed and unemployed women. The sample consisted of 58 employed women and 63 unemployed women residing in Seoul and over 35 years old. The tool used for this study was a structured questionnaire which was revised by the researcher. The tool consisted of 8 items related to demographic characteristics, 47 items on health promotion lifestyle profile, 10 items on self-esteem measurement, l8 items on health locus of control, 21 items on health perception questionnaire. The data collected from the interviews were analyzing using SPSS, yielding frequencies, percentiles, means, standard deviations, t-test, x2-test, Pearson's product moment correlation. The result of this study are as follows : 1) The demographic variables for the two groups were homogenous except for age. 2) No significance differences were found between the two groups on the health promotion lifestyle(t=-.06, p=.954), but there was a statistically significant difference between the two groups on 2 subscale(self actualization and nutrition) of the health promotion lifestyle. Comparison of the order of the scores between the two groups for the employed women showed that the highest score was for nutrition, then self actualization, interpersonal support, stress management, health responsibility and exercise in that order. For the unemployed women, the highest score was for nutrition, then interpersonal support, self actualization, stress management, health responsibility and exercise in that order. 3) There was a statistically significant difference between the two groups on the self-esteem, employed women had lower score on self-esteem than unemployed women(t=-3.37, p=.001). 4) The result of the comparison between the two groups were significantly different for future health status, employed women(mean 3.57) had higher scores than unemployed women(mean 3.25)(t=2.14, p=.034). 5) Comparison of the order of the scores between the two groups showed that the highest score was for internal health locus of control, but there was a statistically no significant difference. However, there was a statistically significant difference between the two groups on the external health locus of control(t=-3.90, p=.000). 6) With regard to the relationship between health promotion lifestyle and self esteem, health locus of control, health perception, there was a correlation between health promotion lifestyle and self-esteem(.41), future health status(.32) health concern(.38), resistance/susceptibility to illness(.39), internal health locus of control(.51) for employed women. For the unemployed women, between health promotion lifestyle and self esteem(.38), future health status(.31), health concern(.40), resistance/susceptibility to illness(.34). In conclusion, on the basis of the results of this study, to improve health promotion lifestyle behaviors by higher the level of perceived health status, health education would be needed to increase the self-esteem and responsibility of health for women.

본 연구는 2007년도 조사된 국가산림자원조사 자료를 이용하여 충북지방에 분포하는 주요 수종에 대하여 평균 연륜생장량과 연륜생장량에 영향을 미치는 인자들과의 상관관계를 분석하고자 하였다. 충북지역에서 조사된 고정표본점은 총 56개소로 다양한 수종이 분포하였으며 그 중 개체수 분포 비율이 높은 10개 수종에 대하여 총 800본의 연륜생장량이 조사된 목편 자료를 대상으로 분석하였다. 충북지방에서 평균 연륜생장량이 가장 높은 수종은 아까시나무(2.30mm/yr)로 나타났고, 그 다음으로는 졸참나무(2.27mm/yr)>산벚나무(1.98mm/yr)>일본잎갈나무(1.98mm/yr) 순으로 나타났다. 대부분 주요 수종들의 경우, 영급과 임분밀도가 증가함에 따라 평균 연륜생장량은 감소하는 경향으로 나타났다. The purpose of this study was to analyze annual tree ring growth characteristics for major tree species distributed in Chungbuk province. A total of 800 sample trees from 56 permanent sampling plots measured by the 5th Korean National Forest Inventory Program in 2007 was used for the calculation of annual growth rates. According to the results of this study, the species of Robinia pseudoacacia(2.30mm/yr) showed the best annual tree ring growth rates and the others are Quercus serrata(2.27mm/yr)>Prunus sargentii(1.98mm/yr)> and Larix leptolepis(1.98mm/yr) in order. Most of the major tree species in Chungbuk province, as tree age and stand density increased, annual tree ring growth rates tended to decreased. This information could be very useful for forest managers to understand annual tree ring growth characteristics in Chungbuk province.
