  • Purpose: The aim of this study was to compare binocular functions such as near point of convergence (NPC), AC/A ratios, heterophoria, accommodation, accommodation lag, positive relative accommodation (PRA), negative relative accommodation (NRA), positive relative convergence (PRC), negative relative convergence (NRC) in normal subjects and convergence insufficiency. Methods: 86 subject (male n=45, female n=41, mean $age{\pm}SD=23.27{\pm}2.85$ years) without amblyopia, strabismus, and ocular pathology were studied. Forty three patients each group were classified as normal subjects and convergence insufficiency group based on AC/A ratio and far and near phoria. Binocular function of the two groups was measured using phoropter. r. Results: The values between normal subjects and convergence insufficiency were 5.71 cm and 7.07 cm for NPC, 5.28 and 2.81 for Heterophria AC/A, 0.92 exo/3.36 exo and 2.17 exo/10.84 exo for far and near phoria, 15.49/23.30/13.30 and 13.50/20.02/9.09 for PRC, respectively. However, there were no significant differences between normal subjects and convergence insufficiency for accommodative amplitude, accommodative lag, PRA, NRA, BI vergence test, BO vergence test, NRC. Conclusions: Both groups were a significant difference for cover test, NPC, Heterophria AC/A, far and near phoria, break point of PRC, and recovery point of PRC.

  • Steers (n = 335) of known genetic backgrounds from four fundamentally different growth types were subjected to two production systems to study the main effects and possible interactive effects on carcass composition. Growth types were animals with genetic potential for large mature weight (LL), intermediate mature weight-late maturing (IL), intermediate mature weight-early maturing (IE), and small mature weight-early maturing (SE). Each year, in a nine year study, calves of each growth type were weaned and five steers of each growth type were developed on pasture or feedlot and harvested at approximately 20 and 14 mo of age, respectively. Data recorded were chilled carcass weight and percentages of forequarter, foreshank, chuck, rib, plate, brisket, hindquarter, round, rump, shortloin, sirloin, flank, lean, fat, bone, and retail cuts. The growth $type{\times}production$ system interaction was an important source of variation in chilled carcass weight (p = 0.0395) and percentage retail cuts (p = 0.001), lean (p = 0.001), fat (p = 0.001), rump (p = 0.0454), shortloin (p = 0.0487), and flank (p = 0.001). The ranking of the growth $type{\times}production$ system means for percentage lean was LL-pasture>IL-pasture = IE-pasture = SE-pasture>LL-feedlot, IL-feedlot>IE-feedlot = SE-feedlot. The growth $type{\times}production$ system interaction was non-significant (p>0.05) for forequarter, foreshank, chuck, rib, plate, brisket, hindquarter, round and bone. Growth types of IE and SE yielded greater (p<0.05) mean forequarter than did growth types of IL and LL ($51.6{\pm}0.3$ and $51.5{\pm}0.3$ vs. $51.1{\pm}0.3$ and $50.8{\pm}0.3%$). Mean bone was highest (p<0.05) for the LL growth type and lowest (p<0.05) for the SE growth type ($19.5{\pm}0.5$ vs. $16.8{\pm}0.5%$). Mean bone was greater (p<0.05) for the pastured steers than for the feedlot steers ($21.8{\pm}0.8$ vs. $14.5{\pm}0.6%$). These data indicate that growth type responded differently in the two production systems and that these results should be helpful in the match of genetics to production resources.

  • Famciclovir, 9-(4-hydroxy-3-hydroxymethylbut-1-yl) guanine, is an oral prodrug of the antiherpesvirus nucleoside analogue, penciclovir. In human, famciclovir is orally well absorbed and then undergoes extensive first pass metabolism to penciclovir and essentially no parent compound is recovered from plasma or urine. The purpose of the present study was to evaluate the bioequivalence of two famciclovir tablets, Famvir tablet 750 mg (Novartis Korea Ltd.) and Famcivir tablet 750 mg (Hanmi Pharmaceutical. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The release of famciclovir from the two famciclovir formulations in vitro was tested using KP VIII Apparatus II method with water. Twenty six healthy male subjects, $23.38{\pm}1.72$ years in age and $68.59{\pm}7.84\;kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After a single tablet containing 750 mg as famciclovir was orally administered, blood samples were taken at predetermined time intervals and the concentrations of penciclovir in serum were determined using HPLC with UV detector. The dissolution profiles of two formulations ere similar at water. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, $Famvir^{(R)}$ tablet 750 mg, were -0.53%, 1.12% and -24.82% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 (e.g., $log\;0.9569{\sim}log\;1.0423$ and $log\;0.8763{\sim}log\;1.2136$ for $AUC_t$ and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Famcivir tablet 750 mg was bioequivalent to Famvir tablet 750 mg.

  • With the emergence of new infectious diseases and changes in the educational environment, the health problems of school-age students are increasing. Accordingly, the role of school health teachers is expanding and becoming more important. The study was to examine the effect of calling on school organizational commitment of school health nurses. Samples were a total of 143 school health nurses working in elementary, middle, and high schools, Gyeonggi-do, South Korea who understood the purpose of this study and voluntarily participated in the study. Measures were Calling and Vocation Questionnaire-Korea (CVQ-K) and organization commitmen questionnaire. Data were analyzed using SPSS/WIN 23.0 program. The analyses showed that the prediction model for school organizational commitment of school health nurses was significant (F=16.142, p<.001). The value of the adjusted R2 was 0.307, which corresponds to the explanatory power of 30.7%. The factor that was found to have the most influence on school organizational commitment of school health nurses was purpose/meaning (β=.28, p=.011), followed by number of classes (β=-.20, p=.006). In order to improve the school organizational commitment of school health nurses, the purpose/meaning and the number of classes should be considered.

  • To investigate the blood lead concentration, their interrelation, correlation factor and influence on pregnant women and newborn, lead concentration in the maternal blood and umbilical cord blood were determined. Samples were collected from 130 mothers who were living in the Taegu City, during March, 1989. Blood lead concentration was estimated using the Atomic Absorption Spectrophotometer(IL. 551) equipped with Flameless Furnace Atomizer (IL. 665). The mean lead concentration of maternal and cord blood were $17.47{\pm}7.92{\mu}g/d{\ell}$, $15.31{\pm}7.98{\mu}g/d{\ell}$, respectively. A significant correlation was observed between the lead concentration of maternal and cord blood, r=0.663, Y=0.667X+3.646. No significant correlation was observed between previous spontaneous abortion and obstetric complication of mother and maternal blood lead concentration. Similarly, no significant correlation was observed between the sex, gestational age of neonate and cord blood lead concentration. But the birth weight of neonate had some negative correlation with cord blood lead concentration. The blood lead concentration of mother who had engaged in manufactures were higher than others and the longer working years were, the higher blood lead concentration were. Significant correlation was observed between husband's occupational exposure to lead and maternal blood lead concentration.

  • Most breeds of sheep in Iran are adapted to their agro ecological niches where it is likely that they were also artificially selected by their owners. In general, most of sheep breeds are multipurpose producing lambs, wool and milk. To compare the physical and chemical composition of the carcasses of ten Iranian native fat-tailed sheep breeds, 243 male lambs (6-7 months of age) of ten fattailed, Iranian breeds of sheep, Sanjabi (S), Ghezel (G), Afshari (A), Mehrabani (M), Lori (L), Lori Bakhtiari (LB), Kordi Khorasan (K), Sangesari (Sa), Baluchi (B) and Chal (C) were studied. Lamb breed group had a significant (p<0.05) effect on all the carcass traits measured. The LB and C lambs showed the same live weight which was significantly (p<0.05) higher than the other breeds. Carcass dressing- out percentage in S lambs was lowest (p<0.05), but not different from G lambs. K and Sa breeds showed the highest (p<0.05) carcass dressing-out percentage. The S lambs had the highest (p<0.05) lean meat percent. Lean meat percentage was not significantly (p>0.05) different in the G, A, M and C breeds. The Sa and K breeds showed the lowest lean meat percent. The S lambs showed the lowest (p<0.05) fat percent in their carcass, while K and Sa showed the highest (p<0.05). Subcutaneous fat in K, Sa and B was higher (p<0.05) than the other breeds. Lambs of S, G, A and M breeds had the lowest subcutaneous fat in their carcasses (p>0.05). Intramascular fat was significantly (p<0.05) lower in M, S and C despite the fact that this values were highest in B and K lambs. The K and Sa breeds had highest fat-tail percentage (p<0.05) in their carcass, whereas S and G showed lowest. Lambs of G, S and A breeds had higher bone percent than other breeds (p<0.05). Lowest bone percent (p<0.05) was seen in K and Sa lambs. The carcass moisture percent was not significantly (p>0.05) different in S, G, A, M, L and C breeds. M lambs showed the lowest crude protein percentage and S breed the highest (p<0.05). There were no significant (p>0.05) differences among other lamb breeds for this trait. Chemical fat percentage was the same in S, G, A, C and M breeds, but significantly (p<0.05) lower from LB, K, Sa and B. Ash percent in S, G and A had no significant (p>0.05) difference. According to higher lean meat and lower fat percentages in the carcass, the ranking of breeds would be S, G, A, M and C.

  • Objective: An experiment was conducted to determine the nutrient intake, digestibility, microbial protein synthesis, haemato-biochemical attributes, immune response and growth performance of Gaddi kids fed with oat fodder based basal diet supplemented with either tea seed or tea seed saponin (TSS) extract. Methods: Eighteen male kids, $7.03{\pm}0.16$ months of age and $19.72{\pm}0.64kg$ body weight, were distributed into three groups, $T_0$ (control), $T_1$, and $T_2$, consisting of 6 animals each in a completely randomized design. The kids were fed a basal diet consisting of concentrate mixture and oat fodder (50:50). Animals in group III ($T_2$) were supplemented with TSS at 0.4% of dry matter intake (DMI), and group II ($T_1$) were supplemented with tea seed at 2.6% of DMI to provide equivalent dose of TSS as in $T_2$. Two metabolism trials were conducted, 1st after 21 days and 2nd after 90 days of feeding to evaluate the short term and long term effects of supplementation. Results: The tea seed ($T_1$) or TSS ($T_2$) supplementation did not affect DMI as well as the digestibility of dry matter, organic matter, crude protein, neutral detergent fibre, and acid detergent fibre. Nutritive value of diet and plane of nutrition were also comparable for both the periods. However, the average daily gain and feed conversion ratio (FCR) were improved (p<0.05) for $T_1$ and $T_2$ as compared to $T_0$. The microbial protein supply was also higher (p<0.05) for $T_1$ and $T_2$ for both the periods. There was no effect of supplementation on most blood parameters. However, the triglyceride and low density lipoprotein cholesterol levels decreased (p<0.05) and high density lipoprotein-cholesterol level increased (p<0.05) in $T_2$ as compared with $T_0$ and $T_1$. Supplementation also did not affect the cell mediated and humoral immune response in goats. Conclusion: Tea seed at 2.6% of DMI and TSS at 0.4% DMI can be fed to Gaddi goats to improve growth rate, FCR and microbial protein synthesis.

  • The purpose of this study is to find out the effects of depression on older adults' metamemory and memory performances. The subjects of the study consisted of 103 older adults over the age of 60 who are living in Kangwon Province. Some data were collected by means of the interview method, using questionnaires for metamemory (MIA questionnaire by Hultsch, et al., 1988), and depression(GDS by Yesavage and Sheikl, 1986). Other data were collected by a testing method on the memory performance, such as the immediate word recall task, the delayed word recall task, the word recognition task(Elderly Verbal Learning Test by Kyung Mi Choi, 1998), and the face recognition task(Face Recognition Task tool developed by this study). The results of this study were as follows: 1) The average point of depressed older persons' metamemory is 3.2 on a 5 point scale and was significantly lower than nondepressed older persons' point of 3.6. Looking into each sub-concept of metamemory, depressed persons' points are higher in terms of task(4.1), but are lower in terms of change(2.3), locus(2.6), and strategy(2.9) in comparison with nondepressed persons' points. 2) Depressed older persons' memory performances are all significantly lower than nondepressed person's, especially in terms of face recognition task(t=7.26, p<.0082) and word recognition task(t=6.58, p<.01). 3) In both depressed and nondepressed persons, metamemory has a close correlation with all memory tasks. In particular, depressed older persons' correlation is higher across the board, especially in memory self-efficacy of metamemory(r=.36 - .49) in comparison with nondepressed persons. 4) According to the results of analysis on the relations between metamemory and memory performances of each memory task using canonical analysis, in the case of depressed older persons, strategy, locus, capability and task have high correlation with word recognition task and delayed word recall task. Also in the case of nondepressed persons, achievement, strategy, change and locus variable have high correlation with face recognition task and immediate word recall task. As mentioned above, depression variables have a negative effect on older persons' metamemory and memory performance. In conclusion, when we care for depressed older persons with less memory ability, we have to consider the outcomes of this study are relevant. In addition, it is necessary to develop nursing intervention in order to prevent memory loss and improve memory performance in depressed older persons.

  • Coronary intervention is now a well established method for the treatment of coronary artery disease. Coronary restenosis is one of the major limitations after coronary intervention. So medical teams advise the patients to get the follow-up coronary angiogram in 6 months after coronary intervention to know if the coronary artery stenosis recurs or not. This study was done in order to know how many patients complied with the advice, and to identify the relative factors to the compliance with getting the follow-up coronary angiogram. The subjects were 101 patients (male: 58 female: 22, mean age: $61{\pm}15$), who received coronary interventions from Jan. 1st to Mar. 31st 1997, and their data were collected from them by questionnaires one year after intervention. The questionnaires consisted of family support scale, self efficacy scale and compliance with sick role behavior scale. The result may be summarized as follows. 1. The number of patients who complied with getting the follow-up coronary angiogram were 37 people(36.6%) and did not comply with it were 64 people(63.4%). All scores of family support(t=5.56, p<.0001), self efficacy (t=4.13, p<.0001) and compliance with sick role behavior(t=5.66, p<.0001) were significantly higher in the patients who got the follow-up coronary angiogram than in those who did not get it. But there was not any relative factor in demographic variables (p>.05). 2. The major motivations for getting follow-up coronary angiogram were recurrence of subjective symptom(40.5%), the advice of medical team(32.4%), and fear of recurrence (27.1%). The restenosis rate in patients who got the follow-up coronary angiogram was 37.8%. 3. The restenosis rate was higher in the patients who had subjective symptoms than in those who did not have any subjective symptom. So subjective symptom and restenosis rate showed a high positive correlation(r=39.9, p<.001). However, 27.2% of the patients who did not have any subjective symptom showed coronary restenosis. 4. The reasons why they did not get the follow-up coronary angiogram were economic burden(37.5%), improved symptom(34.4%), busy life schedule(10.9%), fear of invasive procedure(9.4%), negative reaction of family member(3.1%), no helper for patient(3.1%) and worry about medical team's mistake (1.6%). The relative fators on compliance with getting the follow-up coronary angiogram after coronary intervention were family support, self-efficacy and Compliance with sick role behavior. And the most important reason why the patients did not get the follow-up coronary angiogram after coronary intervention was an economic burden.

  • Between Oct. 1985 and July 1995, 230 patients underwent mitral valve replacement. There were 77 men and 153 women whose mean age was 35.7 years, range 9 to 62 The concomitant operations were 40 aortic valve replacements(17.4%), 25 tricuspid annuloplasties(10.4%), 8 aortic valve replacements & tricuspid annuloplasties(3.5%), 2 tricuspid valve replacements(0.9%) and others, We used 139 mechanical (76 51. Jude medical, 33 CarboMedics, 30 Sorin) and 91 tissue 386 Carpentier-Edwards, 5 lonescu-Shiley) valves. The early postoperative complications occurred in 28 cases. There were 8 low cardiac output syndrome, 5 pleural effusion, 3 significant arrhythmia, 2 cardiac rupture and others. There were 6 early hospital deaths (2.6%) due to low cardiac output syndrome(2), arrhythmia(2) and ventricul r rupture(2). The cuAmulative notal follow-up period was 764. 4 patient-years with a mean of 4).9 months. The long term follow-up information was available for 212 patients(94.6%). There were 21 cases of valve-related complications. Prosthetic valve failure(10), anti-coagulation related bleeding (5), prosthetic valve endocarditis (4), and thromboembolism (2) occurred at rates of 1.3, 0.7, 0.5, and 0.3%Ipt-yr respectively. Late death occurred In 5 cases (0.7%/pt-yr) associated with prosthetic valve endocarditis (2), heart failure (2) and anti-coagulation related bleeding (1). There was no difference in the rate of freedom from prosthetic valve failure between the mechanical and tissue valve group at 6 years (100%), but there was significant difference at 9 years between the tissue (34.4%) and mechanical valve (100%) group (p=0.032). Actuarial survival rates were 98. 8% in tissue valve. 9).7% in mechanical valve group and 96.6% in total patients at 9 years.
