Purpose: The purpose of this study was to describe quality of life in school age children and the relationship between quality of life and parenting attitude as perceived by children and parent-child communication pattern. Methods: Data were collected between May 26 and June 3, 2009 using self-report questionnaires from 148 pairs of children and their parents. The children were enrolled in 4th to 6th grades. The questionnaires included the Parental Bonding Instrument (PBI), Parent-Child Communication (PCC) Scale, and Pediatric Quality of Life Inventory (PedsQL). The data were analyzed using the SPSS WIN 17.0 program. Results: The Quality of Life (QOL) score for the children was significantly higher among children reporting higher parental bonding attitude (mother r=.38, father r=.34) and parent-child communication (mother r=.43, father r=.36). Results of multiple regression showed that factors significantly associated with QOL were academic achievement, caregiver available after school, parent-child communication, school satisfaction, relationship with peers, and birth order among siblings. Conclusion: Positive relationships and good communication with parents and satisfaction with school life were important factors associated with quality of life in school age children.

Body index is known as it affects pulmonary function tests (PFT), so it has been used with predictive formula and nomogram in terms of sex, age, height, etc. Body indices as body weight, body mass index (BMI), and body surface area (BSA) might also affect PFT, so that we have analyzed the correlations between body indices and forced expiratory volume in one second ($FEV_1$), and have done multiple regression analysis to see how body indices affect $FEV_1$. We confirmed that $FEV_1$ had positive correlations with height (r=0.49, p<0.01), body weight (r=0.37, p<0.01), and BSA (r=0.47, p<0.01), inverse correlation with age (r=-0.45, p<0.01), but no correlation with BMI. We found that the 41.9% of $FEV_1$ was diverged from height, age and BSA. Therefore, BSA definitely needs to be considered with predictive formula and nomogram in PFT.

본 연구는 125명의 6-11세 혼합치열기 아동을 대상으로 연령에 따라 초기 혼합치열기 A군(6-8세; 62명)과 후기 혼합치열기 B군(9-11세; 63명)으로 분류하고 유치의 dfs, 영구치의 DFS를 기록한 후 자극성 타액을 채취하여 TYCSB 배지에 배양해서 S. mutans와 S. sobrinus를 구분하였으며 PCR을 시행하여 확인하였다. S. mutans와 S. sobrinus의 분포도와 치아우식증과의 상관관계를 조사하여 다음과 같은 결과를 얻었다. 1. S. mutans와 S. sobrinus의 상관계수는 A군 0.70, B군 0.50로 두 군 모두에서 높은 상관관계를 보였다. 2. S. mutans와 치아우식증과의 관계는 A군(r=0.25)과 B군(r=0.34) 모두에서 약간의 관련성이 나타났다. 3. A군에서 S. sobrinus와 치아우식증간에 상관관계가 없는 것으로 나타났으며, B군(r=0.21)에서는 미약한 상관관계가 성립되었다. 4. S. mutans와 나이의 상관관계는 A군과 B군 모두에서 관련성이 없는 것으로 나타났다. 5. S. sobrinus와 나이의 상관관계는 A군(r=0.32)에서는 약간의 관련성이 나타났고, B군에서는 관련성이 없는 것으로 나타났다.

The age and growth of the skipjack tuna Katsuwonus pelamis were determined using otoliths sampled from a Korean tuna purse seine fishery in the Western and Central Pacific Ocean from January 2005 to September 2006. A total of 312 otoliths were used to estimate the ages of skipjack tuna, which ranged from 1 to 7 years. The relationships between otolith ring radius (R) and fork length (FL) for female, male, and sex combined were FL = 19.74R + 1.50 ($r^2=0.54$), FL = 17.66R + 6.35 ($r^2=0.47$), and FL = 18.83R + 3.36 ($r^2=0.53$), respectively. The back-calculated fork lengths of each age ($FL_{year}$) were $FL_1=36.2cm$, $FL_2=43.3cm$, $FL_3=48.3cm$, $FL_4=52.6cm$, $FL_5=56.5cm$, $FL_6=60.8cm$, and $FL_7=63.2cm$. The relationships between fork length (FL) and total weight (TW) for female, male, and sex combined were $TW=0.00001FL^{3.19}(r^2=0.95)$, $TW=0.00001FL^{3.17}(r^2=0.95)$, and $TW=0.000009FL^{3.23}(r^2=0.95)$, respectively. The von Bertalanffy growth parameters of skipjack tuna estimated in this study were $L_{\infty}=77.4cm$, K = 0.176/year, and $t_0=-2.569years$.

TD= 22.58R-6.01 (r=0.960) 3. 월별 연변성장율 ($MGR\;:\;(R-r_n)/(r_n-r_{n-1})$)조사에서 추정한 윤문형성시기는 3월에서 5월 사이였다. 4. 각장조성의 월별 성장 경향은 12월에서 이듬해 3월 사이가 주 성장기였고, 4월에서 6월 사이는 성장의 휴지기, 그 외의 기간은 아주 완만한 성장을 하였다. 5. Bertalanffy식이 Gompertz식과 Logistic식보다 잔차 평방합이 적었고, 그 성장식은 다음과 같았다. $$L_t=46.65 (1-e^{-0.283(t+9.210)})$$, $$W_t=44.90 (1-e^{-0.283(t+9.210)})^3$$

Age and growth of the blue spot mudskipper (Boleophthalmus pectinirostris) were studied using the samples caught in the mud flats of southwestern Korea during April-October, 2001. The value of the marginal index of the second actinost bone was the lowest in July and October and indicated by rings that was analysis of formed teice a year. The relationship between body weigt (BW) and total length (TL) was expressed as BW=0.000005 $TL^{3.12}\;(r^2=0.92)$ for females and BW=0.000476 $TL=^{2.18}\;(r^2=0.62)$ for males. Regression analysis of TL-BW between sexes showed a significant difference (P<0.01). Relationship between total length (TL) and actinost radius (R) were expressed as TL=16.9+33.4 R $(r^2=0.62)$ for females and TL=45.8+26.2 R $(r^2=0.41)$ for males. Growth parameters, $L\infty,t_0$ and K were estimated as 165.2 mm, -0.23, and 1.07 for females and 155.3 mm, -0.35, and 1.39 for males.

목적: 본 연구는 고령의 성인을 대상으로 굴절이상과 안광학 성분들 사이의 연관성을 알아보고자 하였다. 방법: 안과적 수술을 받지 않은 고령의 95명을 대상으로 굴절이상과 각막곡률반경, 각막굴절력, 안축장, 전방깊이, 수정체 두께를 측정하고 분석하였다. 결과: 안축장(AL)/각막곡률반경(CR) 비와 각막굴절력, 안축장, 전방깊이는 양의 상관관계를 보였고(r=0.510, r=0.439 r=0.411), AL/CR 비와 각막곡률반경과는 음의 상관관계를 나타냈다(r = -0.516). 각 막굴절력과 안축장 사이에서 가장 높은 연관성(r = -0.545, p=0.000)을 보였으며 굴절이상과 AL/CR 비는 음의 상관관계로 분석되었다(r = -0.359). 결론: 눈의 굴절이상을 진단하는데 AL/CR 비가 고령의 성인에서 중요한 지표자료임을 알 수 있었다.

In this paper, all rings or (left)near-rings R are associative, and for near-ring R, all R-groups are right R action and all modules are right R-modules. First, we begin with the study of rings in which all the additive endomorphisms or only the left multiplication endomorphisms are generated by ring endomorphisms and their properties. This study was motivated by the work on the Sullivan's Problem [14]. Next, for any right R-module M, we will introduce AM modules and investigate their basic properties. Finally, for any nearring R, we will also introduce MR-groups and study some of their properties.

Spirituality is the dynamic and inherent dimension of humanity. This study aimsto evaluate the relationship between Spiritual Health, Mindfulness and Emotion Regulation among French Emerging Adults. An online cross-sectional survey design consisted of four hundred and twenty-one samples were recruited from different universities at Strasbourg, France. Participant's age ranged from 18 to 28 years with a mean age of 20.77 years (SD=2.22). The results, highlights that Spiritual Health Measure was significant and positive association with Mindfulness (r=.45, p < .01) and Reappraisal (r=.22, p < .01). Further, the significant negative correlation observed with Spiritual Dissonance (r=.44, p < .01) and Suppression (r=.24, p < .01). These findings support emerging literature on Spiritual Health. Future studies should evolve an intervention model to promote Spiritual Health and Positive Health.
