The purpose of this study was to analysis level on family caregiver's burden for the elderly with senile dementia in a rural area and to choose priority care group, thereby facilitating the development of interventions to reduce the caregiver's burden. For this purpose, data were collected by questionaire from June 10 to October 8, 1994. The instruments for data collection were Caregiver Burden Inventory by Novak(1989) and Zarit et al(1982), severity of dementia by Hughes Scales (1982), ADL by Lawton (1971), patients' family caregiving activity by pre-survey and reference review(Lee, 1993 ; Jang, 1990 ; Yoo, 1982). The subjects were 60 family caregiver of senile dementia in a rural area. The data was analysed by the use of t-test, ANOVA, correlation and multiple regression. The results were as follows : 1. Total burden was evaluated over average, the mean of family burden was 61.24. 2. Significant variables which were correlated to the family caregiver's burden were the severity of dementia(F=30.52, p<0.001), ADL(F=5.43, p<0.01), PADL(F=6.14, p<0.01), caregiver's health status(F=6.05, p<0.01), a view of patient's prognosis(F=4.08, p<0.05), the number of hours per day spent on caregiving(F=19.64, p<0.001), level of intimacy of caregiver and patients(F=7.16, p<0.001), the frequency of caregiving activity(F=5.31, p<0.01). 3. ADL was the most important predictor to family caregiver burden(R2=0.6611). In addition to this, the severity of dementia, level of intimacy of caregiver and patient, relationship with the patient accounted for 79% of family caregiver burden. 4. The criteria of priority care group were as follows ; the mean of family caregiver burden was above 58, above of moderate ADL, the number of hours per day spent on caregiving above of 8 hours, above of moderate dementia. By the the severity of dementia, number of priority care group, mild dementia was 10(43.4%), moderate dementia 23 (92.0%), sever dementia 12(100.0%).

Let $T^{\alpha}_{\lambda}$(p, A, B) denote the class of functions $$f(z)=z^p-{\sum\limits^{\infty}_{k=1}}{\mid}a_{p+k}{\mid}z^{p+k}$$ which are regular and p valent in the unit disc U = {z: |z| <1} and satisfying the condition $\left|{\frac{{e^{ia}}\{{\frac{f^{\prime}(z)}{z^{p-1}}-p}\}}{(A-B){\lambda}p{\cos}{\alpha}-Be^{i{\alpha}}\{\frac{f^{\prime}(z)}{z^{p-1}}-p\}}}\right|$<1, $z{\in}U$, where 0<${\lambda}{\leq}1$, $-\frac{\pi}{2}$<${\alpha}$<$\frac{\pi}{2}$, $-1{\leq}A$<$B{\leq}1$, 0<$B{\leq}1$ and $p{\in}N=\{1,2,3,{\cdots}\}$. In this paper, we obtain sharp results concerning coefficient estimates, distortion theorem and radius of convexity for the class $T^{\alpha}_{\lambda}$(p, A, B). It is further shown that the class $T^{\alpha}_{\lambda}$(p, A, B) is closed under "arithmetic mean" and "convex linear combinations". We also obtain class preserving integral operators of the form $F(z)=\frac{p+c}{z^c}{\int^z_0t^{c-1}}f(t)dt$, c>-p, for the class $T^{\alpha}_{\lambda}$(p, A, B). Conversely when $F(z){\in}T^{\alpha}_{\lambda}$(p, A, B), radius of p valence of f(z) has also determined.

Habitual speaking fundamental frequency (sF0) plays an important role in determining the voice classification, which can be presented differently depending on the vocal fold length and language habits. The purpose of this study, therefore, was to compare the differences in sF0 for voice classification and closed quotient between speaking and singing. Seventeen singers (7 sopranos, 5 tenors, 5 baritones, mean age 25.1 years) with no evidence of vocal folds pathology were participated. sF0 and closed quotient (CQ) both in speaking and in singing (A3-A5 with soprano, A2-A4 with tenor and baritone) were measured using SPEAD program and electroglottography. No significant differences were observed for sF0 between tenor and baritone groups (p> 0.05). However, CQ in singing was significantly different among three groups (p< 0.05), but CQ in speaking was not (p> 0.05). Furthermore, CQ was significantly different with both soprano (p< 0.01) and tenor groups ((P= 0.02) whereas baritone group revealed there is no difference when compared between speaking and singing. No significant differences in sF0 between tenor and baritone participants may result from decision-making for voice classification by experience and should measure sF0 before determining the voice classification.

Apoptosis is essential for a variety of pathophysiological progress. Apoptosis induction by various agents changes cellular morphology, DNA content and lipid membrane composition. Recently, sphingosine 1-phosphate (S1P) is avidly released from not only platelets and erythrocytes but vascular endothelium. Here we established S1P releasing cells by deleting S1P lyase (F9-12 cells). We observed apoptosis induction by the treatment of fumonisin B1 (FB1) in F9-12 cells but not in F9 wild-type cells. We measured high amounts of accumulated S1P and dihydroS1P (DHS1P) in FB1-induced apoptotic F9-12 cells. We also showed DHS1P release in an early stage of the apoptosis induction by FB1 but not by phorbol 12-myristate 13-acetate (PMA)-induced apoptosis, suggesting differential apoptotic processes.

Purpose: To suggest ideas that promote sexual health and useful in planning sex education programs for middle school students. Method: This study surveyed 661 middle school students from three schools in Seoul and Chunchon. Result: The average degree of sexual knowledge was 31.5, while attitude was 32.5. There were statistically significant differences in sexual knowledge in relation to: coeducational environment (t=-5.776, p=.000), grade (F=36.351, p=.000), father's age (t=-2.510, p=.012), mother's age (t=-2.146, p=.032), economical status (F=3.264, p=.039), source of sexual knowledge (F=8.484, p=.000), the degree of interest in the opposite sex (F=16.871, p=.000), sexual discussions with parents (t=3.556, p=.000), sexual discussions with teachers (t=2.847, p=.005), and sex education (t=2.148, p=.032). Likewise, stastically significant differences in sexual attitudes were linked to: coeducational environment (t=-7.646, p=.000), subject's grade (F=32.743, p=.000), parental marriage status (t=2.338, p=.020), mother's age (t=-2.048, p=.041), source of sexual knowledge (F=6.917, p=.000), the degree of interest in the opposite sex (F=15.559, p=.000), sexual discussions with parents (t=3.908, p=.000), and sexual discussions with teachers (t=2.946, p=.003). The students level of sexual knowledge and attitude was significantly correlated (r=.686, p=.000). Conclusion: This study indicates a variety of systematic sexual education programs are needed for middle school student at home and school.

Korea is one of the typical rice eating countries where availability of animal protein is limited even for the growing generation. Nutritive food products for infants and children are not available commercially in large scale at the present time, although a limited amount of expensive milk products are produced. The present study deals with a pioneering attempt on a new food mixture to meet this demand. Several food mixtures, possibly produced in the country, consisting of rice, soybean, FPC, vitamin, minerals and other food additives are developed in this work Sixty female and male rats aged $30{\sim}40$ days were divided into five groups, twelve rats each. The rats had been maintained with the six different diets, as follow. Formulation of proposed infant food mixturesComposition F-R-1 F-S-2 F-F-3 F-P-4 S Rice 100% 40% 37% 46% 70% Sugar - 12 13 10 70 Casein - - - - 20 Bean - 40 37 24 - Yeast - 3 2 3 - Mineral Vitamain - 2 4 2 4.3 F.P.C - 3 4 7 - Fat - - 4 8 4 Cod liver Oil - - - - 3 The findings of this study presented in FER, PER, final organ weights, body weights growth, percentage of nitrogen retention in the body. F-P-4 group tended to remain the heaviest and F-R-1 the lightest in the body weight among three groups throughout the experimental period. In terms of FER (Feed Efficiency Ratio) and PER (Prortein E. R.) value, F-P-4 group kept the highest record throughout. F-P-4 group showed the highest value of nitrogen retention in the body. In comparision between F-P-4 groups and casein 20% group (standard) in all respects of this experiment, F-P-4 group which is the most superior among experimental group, revealed statisfically no significant inferior than that of standard group. This fact could be interpreted that most limiting a. a., methionine in the soy protein produced little inferiority of the experimental groups in the study.

We are concerned with the following fractional p-Laplacian inclusion: $$(-{\Delta})^s_pu+V(x){\mid}u{\mid}^{p-2}u{\in}{\lambda}[{\underline{f}}(x,u(x)),\;{\bar{f}}(s,u(x))]$$ in ${\mathbb{R}}^N$, where $(-{\Delta})^s_p$ is the fractional p-Laplacian operator, 0 < s < 1 < p < $+{\infty}$, sp < N, and $f:{\mathbb{R}}^N{\times}{\mathbb{R}}{\rightarrow}{\mathbb{R}}$ is measurable with respect to each variable separately. We show that our problem with the discontinuous nonlinearity f admits at least one or two nontrivial weak solutions. In order to do this, the main tool is the Berkovits-Tienari degree theory for weakly upper semicontinuous set-valued operators. In addition, our main assertions continue to hold when $(-{\Delta})^s_pu$ is replaced by any non-local integro-differential operator.

For $1{\leq}p$, $q{\leq}{\infty}$ and $s{\in}\mathbb{R}$, it is proved that there exists a constant C > 0 such that for any $f{\in}B^{s+2}_{p,q}(\mathbb{R}^n)$ $${\parallel}f{\parallel}_{B^{s+2}_{p,q}(\mathbb{R}^n)}{\leq}C{\parallel}f\;-\;{\Delta}f{\parallel}_{B^{s}_{p,q}(\mathbb{R}^n)}$$, which tells us that the operator $I-\Delta$ is $B^{s+2}_{p,q}$-coercive on the Besov space $B^s_{p,q}$.

The purpose of this study was to examine vegetable & fruit (V/F) intakes, beliefs and self-efficacy regarding V/F consumption, nutrition knowledge and eating behavior of elementary students. A survey was conducted to the 4th graders (n = 234) at two elementary schools in Guri, Kyunggi-do. About one-fourth of subjects were overweight or obese. Subjects had 4.2 servings of V/F a day, consuming 340.2 g of V/F. Girls consumed significantly more amounts of vegetables than boys (p < 0.05). Girls were more favorable regarding V/F consumption (p < 0.01), and believed more strongly on advantages of having V/F such as “good for skin” constipation prevention (p < 0.001) and cancer prevention (p < 0.05). Boys felt more strongly in disadvantages or barriers of eating V/F, including mother's cooking time constraints (p < 0.01), lack of past experience of eating V/F, and family members' disliking of V/F (p < 0.05). Girls felt more confident in eating V/F (p < 0.05) than boys; they also felt more confident in specific items of "eating fruits/salads instead of cookies/chips for snack" and "eating fruit juice/vegetable juice instead of soda"(p < 0.01). Subjects showed low level of nutrition knowledge, especially in items such as balanced meals, recommended servings of V/F and vitamin deficiency. Compared to boys, girls had more desirable eating behavior such as eating adequate amount of meals (p < 0.001), having a variety of foods, eating fruits daily, and having fatty foods less frequently (p < 0.05). Intakes of Ca and K were quite below the recommended level, while the intakes of protein, Na and vitamin A intake were much above the Dietary Reference Intakes (DRI) for 9-11 old children. Nutrient intakes expressed as %DRI was higher in girls for vitamin A (p < 0.01), energy and riboflavin (p < 0.05). High V/F consumption group (${\geq}5$ servings of V/F a day) compared to the counterparts showed higher self-efficacy and had better eating behaviors. Nutrition education for children should focus on increasing consumption of V/F, by helping them to increase self-efficacy for eating V/F and to recognize the benefits and reduce the barriers of eating V/F, especially in boys. It is also needed to provide nutrition information for balanced meals or increasing V/F consumption, and help the children to adopt desirable eating behavior.

The cPCR technique was used to monitor rumen fermentation and attachment of Fibrobacter succinogenes to cellulose at different pH in the in vitro culture medium. The target fragments of 16S rDNA(445 bp) were amplified from genomic DNA of F. succinogenes with specific primers and internal controls(205 bp) were constructed. Cell counts were estimated from the amounts of genomic DNA, which was calculated from cPCR results. F. succinogenes in pH 6.8 and 6.2 showed apparently higher attachment than in pH 5.8 during all incubation time. There were some difference between pH 6.8 and 6.2 in the degree of attachment, but the different was not significant (P>0.05). Cellulose degradation increased in process of incubation time and the increasing rate was higher when initial pH was higher. The pH in culture medium decreased regardless of initial pH in course of incubation time. After 24 h of incubation, medium pH was dropped by 0.24, 0.58 and 0.16 units from original medium pH 6.8, 6.2 and 5.8, respectively. More gas was produced at higher initial pH in the same manner as in cellulose degradation. In summery, Initial pH of rumen culture in vitro significantly influenced cellulose digestion, gas production, pH change and bacterial attachment. Especially, low pH(5.8) resulted in much lower bacterial attachment and fiber digestion compared to higher medium pH.
