This study is to investigate the patients who had blepharoplasty for cosmetic purposes or facial nerve disorders. 21 patients were examined with an age from 17 to 63 years. Sixteen cases were classified as a normal group for investigation of the histopathologic change according to the age. The rest were patients of Bell's palsy(2), $Botox^{(R)}$ injection(2) and blepharospasm (1). We measured a mean diameter of myofiber and dimension's proportion of muscluar tissue per regular visual field. First, we measured a statistical significance according to the age in normal cases by grouping them into younger than 30-year-old, 30's, 40's, 50's and 60's. Second, we divided normal cases(16) into Group A and B by two bases for statistical analysis. In conclusion, although there were several differences as vacuolation, internalization of sarcolemnic nuclei between 35-year-old and 62-year-old patients in simple comparison, there was no uniform decrease according to the age. There were also no significant statistical changes in the value of a diameter of myofibers and dimension's proportion of muscular tissue according to the age in any of the two normal groups. But in $Botox^{(R)}$ injection and Bell's palsy, blepharospasm patients, two values showed remarkable difference compared to the normal group of same age.

On the basis of the study intended to research by cross-sectional study keeped pace with semi-longitudinal study the growth accelerating phenomena that MGA(Maximum Growth Age) in teenager's body height. The duration of study is from Oct. 1st. 1991 to September 30 1992 and the data are analysed through computer. The body height and MGA of Koreans who had been for during the period from 1898 to 1973 proved transition of the growth accelerating phenomena by research data reported between 1913 and 1990. The results are as follows: 1. Maximum Growth Age The MGA's in body height of male are respectively the age 15.024 in 1913, 14.28 in 1940, 13.65 in 1959, 13.86 in 1967, 12.52 in 1983, 11.39 in 1987, 12.36 in 1990, while those of female are the age of 12.0 in 1940, 12.36 in 1959, 10.45 in 1969, 11.15 in 1985, 10.27 in 1988, 10.23 in 1990 ; these data show that the MGA of the Korean has been getting younger. 2. The correlation of the MGA's in body height are as below ; Male ; r = -0.448(p<0.01) Female ; r = -0.404(p<0.05) 3. The equation of linear regression of MGA's in body height are as below ; Male ; Y(MGA) = -0.0316X(the year)+75.297 Female ; Y(MGA) = -0.035X(the year)+79.986 4. The MGA's in body height are shown in Table 3. 5. From the transition of the growth accelerating phenomena, we can compute the fact that the MGA's has been getting younger by 0.3 year per 10 years. 6. The future growth accelerating phenomena in body height, the MGA's of male are respectively the age 12.25 in 1995, 12.09 in 2000, 11.94 in 2005, 11.78 in 2010, while those of female are the age of 10.16 in 1995, 9.98 in 2000, 9.81 in 2005, 9.64 in 2010, these data show that the MGA of female are more younger than that of male.

This study was performed to establish a new parameter for estimating gestational age and predicting parturition day by ultrasonographic measurement of deep portion of telencephalic vesicle (DPTV) diameter in small dogs. Fetal head diameter (HD) and DPTV diameter were measured in 15 pregnant Pekingese bitches, from Day 15 to the parturition day, and evaluated the correlation between gestational age. HD was measured from day 29 of pregnancy to parturition day and increased from $4.9{\pm}2mm$ to $25.5{\pm}0.7mm$. Especially, from day 38 of pregnancy to parturition day, HD uniformly increased about 0.6 mm per day and was significantly and linearly relative to gestational age during this period ($r^2$ >0.99). DPTV diameter was measured from day 35 to day 60 of pregnancy and increased from $3.2{\pm}0.9mm$ to $11.5{\pm}0.7mm$. Especially from day 38 to day 60 of pregnancy, DPTV diameter uniformly increased about 1 mm per 3 days and was significantly and linearly relative to gestational age during this period ($r^2$ >0.99). In conclusion, DPTV diameter could to be a useful parameter for the estimation of gestational age and the prediction of parturition day when used alone or in combination with HD during the second half of pregnancy.

Studies were conducted on the effect of pruning time, host age, conidial dispersal and weather parameters on the incidence and severity of mulberry leaf spot (Myrothecium roridum). The disease severity (%) increased with increase in shoot age irrespective of pruning date. Maximum disease severity was observed in plants pruned during first week of April and minimum disease severity in plants pruned during first week of March. Significant (P ＜ 0.01) influence of date of pruning, shoot age and their interaction was observed on severity of the disease. Apparent infection rate (r) was significantly higher during the plant growth period from day 48 to day 55. Average apparent yale was higher in plants pruned during first week of April and least in plants pruned during first week of July. The disease infection was negatively correlated to distance from the inoculum source. Leaf spot severity (%) was influenced by weather parameters. Multiple regression analysis revealed contribution of various combinations of weather parameters on the disease severity. Linear prediction model $(Y ＝ －81.803＋1.176x_2＋0.765x_3) with significant $R^2$ was developed for prediction of the disease under natural epiphytotic condition.

This study was conducted to determine the effect of DL-methionine (Met) and DL-methionine hydroxy analogue (MHA) supplementation on the growth performance, contents of serum amino acids and activities of digestive protease in broiler chicks from 0 to 3 weeks old . There were three treatments in this study: (1) control (basal diet), (2) 0.24% Met supplementation and (3) 0.368% MHA supplementation. The results showed that Met and MHA supplementation did not significantly (p>0.05) improve feed efficiency and body weight gain for broilers from 0-1, 0-2 and 0-3 weeks of age. The serum levels of homocystine, methionine and taurine were significantly (p<0.05) higher with supplementation of Met or MHA than with control. The pepsin activity of proventriculus was increased with (p<0.05) Met supplementation at 21 days of age and with MHA supplementation at 7 and 14 days of age. The trypsin activity was also increased (p<0.05) with MHA supplementation at 7 days of age. The chymotrypsin activity in pancreas and the dipeptidase activity in small intestinal mucosa and content were not affected (p>0.05) by Met or MHA supplementation.

Impact of pruning date, shoot age and weather parameters on the severity and development of grey leaf spot (Pseudocercospora mori) of mulberry was studied. The disease severity (%) increased with increase in shoot age irrespective of pruning date. Maximum disease severity was observed in plants pruned during second week of October and minimum in plants pruned during last week of December. Significant (P<0.05) influence of date of pruning, shoot age and their interaction was observed on the severity of the disease. Apparent infection rate (r) was significantly higher during plant growth period from day-48 to day-55. Average apparent rate was higher in plants pruned during first week of September and least in plants pruned during third and fourth week of December. Multiple regression analysis revealed contribution of various combinations of weather parameters on the disease severity. A linear prediction model [$Y=66.05+(-1.39)x_1+(-0.219)x_4$] with significant $R^2$ was developed for prediction of the disease under natural epiphytotic condition.

The purpose of this study was to investigate dietary intake and to evaluate patient satisfaction toward the quality of hospital foodservice. Questionnaires were distributed to 203 hospitalized patients in 3 hospitals having 300 beds. The intake rates for served amounts of rice, side dishes, and soup were 72.5%, 68.2%, and 62.6%, respectively. The main reasons for left-overs were 'no appetite' (25.8%) and 'not salty enough' (19.9%). The rate of patients eating outside food was about 33.5%. The average score for quality satisfaction of meal characteristics was 3.34 ${\pm}$ 0.61, and the average score for quality satisfaction of sanitation and service characteristics was 3.58 ${\pm}$ 0.61. 'Seasoning' showed the lowest score and 'temperature' showed the highest score for quality satisfaction of meal characteristics. In the quality satisfaction of sanitation and services, 'explanation of meals' showed the lowest score and 'exactness of meal times' showed the highest score. The patients hospitalized for 10 days showed significantly lower average scores than those hospitalized over 60 days for quality satisfaction of meal characteristics. The patients with 'little appetite' and 'regular appetite' showed significantly lower average scores than those with 'much appetite' for the quality satisfaction of meal, sanitation, and service characteristics. The patients who 'rarely had leftovers' showed significantly higher average scores than those who 'always had leftovers' and 'often had leftovers' for quality satisfaction of meal characteristics. Meal characteristic scores were significantly correlated with age (r = 0.216), length of admission (r = 0.310), appetite (r = 0.251), leftovers (r = 0.233), and intake of soup (r = 0.205). Also, sanitation and service characteristics scores were significantly correlated with age (r = 0.327), education (r = -0.202), length of admission (r = 0.168), and appetite (r = 0.155). Thus, it would seem to be desirable that hospital foodservices improve the taste and seasoning of meals and provide appropriate nutrition education and counseling in mid-sized hospitals.

본 연구의 목적은 노인 고혈압 환자의 건강행태, 수면 관련 요인이 인지기능에 미치는 영향을 파악하는 것이다. 연구대상은 지역사회에 거주하는 65세 이상 노인 중 고혈압을 진단 받은 140명이었다. 자료 수집은 2013년 2월 5일부터 5월 1일까지로 일대일면접 설문조사로 시행되었다. 연구도구는 Pittsburgh Sleep Quality Index(PSQI), Epworth Sleepiness Scale(ESS)와 한국어판 노인용 간이정신상태 검사 도구를 사용하여 측정하였다. 연구결과, 노인고혈압 환자의 인지기능은 수면의 질 저하와 유의한 음의 상관관계를 나타냈다(r=-.29, p<.001). 수면시간은 체질량지수(r=-.18, p=.032) 및 수면의 질 저하(r=-.59, p<.001)와 유의한 음의 상관관계가 있었고, 주간졸음과는 유의한 양의 상관관계가 있었다(r=.22, p=.008). 위계적 회귀분석 결과, 노인 고혈압 환자의 연령, 교육수준, 거주유형은 인지기능과 유의한 관련성이 있으며(F=8.56, p<.001, Adjusted $R^2=.14$), 인구사회학적 특성과 건강행태를 통제한 상태에서 수면의 질 저하(${\beta}=-.27$, p=.008)는 인지기능에 유의한 영향을 미치며, 최종 모형의 설명력은 17%였다(F=4.09, p<.001). 그러므로 노인 고혈압 환자의 인지기능 향상전략은 연령, 교육수준, 거주유형을 고려하고, 낮은 수면의 질을 향상 시킬 수 있는 치료적인 중재가 도움이 될 것으로 사료된다.
