The bilateral cleft lip, a more severe form of clefting than unilateral cleft lip, involves separation of the lip along philtral lines, isolating the central segment (prolabium). Bilateral cleft lip may be either symmetrical or asymmetrical, in which case the cleft lip is split more on one side than on the other. The cleft affects the obvious facial form as an anatomic deformity and has functional consequences, affecting the child's ability to eat, speak, hear, and breathe. Although there would seem to be quite a variance in reported figures, ratios of cleft lip with or without cleft palate have gone as high as 1:500 and as low as 1:1000. It is known that less than 10% of cleft lips are bilateral. Although bilateral cleft lip is less common than unilateral cleft lip, the deformity is more severe, and the reconstructive technique is more complex. Surgery is the only treatment necessary for patients with bilateral cleft lip. Accompanying the evolution of surgical repair is the increasingly important role of orthodontic support with early presurgical alveolar and nasal molding. Repositioning the maxillary and alveolar segments into a more anatomic position allows the surgeon to repair the lip and associated nasal deformity under more optimal conditions. The purpose of this article is to review the related anatomy, presurgical management, and surgical management of bilateral cleft lip.

Effective parenting attitudes have been known to be associated with children's health practices including dietary intake and physical activity. The objective of this study is to compare children's body weights and eating habits by maternal parenting attitudes. Data were collected at school (N = 396; 4th and 5th grade students) using self-administered questionnaires on maternal parenting attitudes, eating habits and physical activity. Parenting attitudes were categorized as 1 of 4 parenting attitudes (overprotective, authoritarian, democratic, and neglectful) using affection and control median cut points. Children's body weights, frequency of breakfast, eating out and fastfood, and physical activity were compared by maternal parenting attitudes. Children's body weights were related with mother's employment status (p < 0.05) and parenting attitudes (p < 0.01). Children of unemployed mothers were more likely to be overweight. Children of neglectful mothers (p < 0.01) were more likely to be underweight, compared with children of mothers with other parenting attitudes. Since, unfortunately, the number of children of neglectful mothers was very limited in this study, we could hardly assess eating habits of children of neglectful mothers. Children of authoritarian mothers ate breakfast more regularly (p < 0.05), but ate snacks less regularly (p < 0.01). Children of democratic mothers ate fastfood less frequently (p < 0.01) and ate snacks more regularly (p < 0.01). Meanwhile, children of overprotective mothers ate breakfast less regularly (p < 0.05) and ate out less frequently (p < 0.01). However, maternal parenting attitudes were not related to children's physical activities. In conclusion, the maternal democratic parenting attitude was associated with healthy eating habits including regular snack time and less fastfood. On the other hand, the maternal neglectful parenting attitude was associated with high risk of children's underweight. Understanding the mechanism through which parenting attitude is related with underweight risk and healthy eating habits may lead to the development of better interventions.

The purpose of this study is to identify factors influencing a health-promoting lifestyle among highly educated, married women with or without work outside the home. It is a direct interview, cross-sectional study. Subjects were 250 married, unemployed women and 236 married women employed as teachers. Women who have not graduated college, work only part-time or have no current spouse were excluded. The instruments used were the Health-Promoting Lifestyle Profile (Walker, et al., 1987) and the Habitual Physical Activity Questionnaire (Backe, et al., 1982), The HPLP scores of the employed, married women were significantly lower than those for unemployed respondents. for both groups of respondents, the self-actualization subscale was the highest score and the exercise subscale was the lowest score. The HPLP indicated that exercise is a very weak area. Thus, an increase in exercise time and frequency, especially for highly educated, married women, is suggested. Multiple regression analysis revealed that a health-promoting lifestyle of unemployed, married women was affected by sports activity, leisure-time activity, depression and satisfaction of role allotment. On the other hand, a health-promoting lifestyle of employed, married women was affected by sports activity, leisure-time activity, stress, self-perceived economic status, coffee consumption, husband's help, and maid's help. That is, with more sports activity and leisure-time activity, less depression and more satisfaction of role allotment, unemployed, married women would have higher HPLP scores. Also, with more sports activity and leisure-time activity, less stress, better self-perceived economic status, less coffee consumption, more husband's help and more maid's help, employed, married women would have higher HPLP scores. The results indicate that sports activity and leisure-time activity were the first and the second determinants of health-promoting lifestyle respectively. Therefore, an exercise-centered health-promoting program for highly educated, married women is suggested in the community or workplace. Especially, the program should be designed to be easily approachable for highly educated, employed married women who have more of a role burden compared to unemployed women.

This study was carried out for the stability analysis of earth dam by the variation of compaction density. The test samples were taken from five kinds of soil used for banking material and the degree of compaction for this samples were chosen 100, 95, 90, 85, and 80 percent. The stability problems were analysed by the settlement and camber( extra banking) of dam, strength parameter and dam slope, and coefficient of permeability and seapage flow through dam body. The results of the stability analysis of earth dam are as follows. 1. The more the fine particle increases and lower the compaction degree becomes, the lower the preconsolidation load becomes but the compression index becomes higher. 2. Sixty to eighty percent of settlement of dam occurs during the construction period and the settlement ratio after completion of dam is inversly proportional to the degree of compaction. 3. The camber of dam has heigher value in condition that it has more fine particle(N) and heigher dam height(H) with the relation of H= e(aN-bH-e). 4. The cohesion(C) decreases in proportion to compaction degree(D) and fine particle(N) with the relation of C= aD+ bN-c, but the internal friction angle is almost constant regardless of change of degree of compaction. 5. In fine soil, strength parameter from triaxial compression test is smaller than that from direct shear test but, they are almost same in coarse soil regardless of the test method. 6. The safety factor of the dam slope generally decreases in proportion to cohesion and degree of compaction but, in case of coarse soil, it is less related to the degree of compaction and is mainly afected by internal friction angle. 7. Soil permeability(K) decreases by the increases of the degree of compaction and fine particle with relation of K=e(a-bl)-cN) 8. The more compaction thickness is, the less vertical permeability (Kv) is but the more h6rzontal permeability (KH) is, and ratio of Kv versus KH is largest in range from 85 to 90 percent of degree of corn paction. 9. With the compaction more than 85 percent and coefficient of permeability less than ${\alpha}$X 10-$^3$cm/sec, the earth dam is generally safe from the piping action.

The study aims to explore the individual and group agreement of the direct payment of less-favored areas in Japan. This study was conducted by literature review, specialist interview and field visiting. The results of this study were as follows. First, direct payment policy in Japan was consisted of three components which were to maintaining multiple functions, to reorient agriculture sector, and to revitalizing the community activities. Second, the purposes of direct payments with conversion program is to reorient agriculture and revitalize the community activities which were changed from sustaining existing agriculture. Third, the conditions of group agreement is to make a agreement that a group of farmers should make a five-year agreement stipulating activities necessary to prevent the abandonment of farmland and to be more than one hector, and good agricultural practice or other activities favorable or friendly to environment should be implemented. As individual and group agreement, the land area of direct payment was 662,000 ha in less favored areas. In conclusion after direct payment in less favored areas, the abandonment of farmland was mitigated, and the agricultural production activities and community activities had become more vigorous through the discussion for planning their own land in the village.

Minimally invasive surgery (MIS) has several advantages over conventional open surgery. Less pain, less morbidity, early recovery and better cosmetic outcomes are well-known benefits of MIS. However, indications of MIS are highly dependent on the experience of surgeon and the disease status, In the benign diseases with less surgical complexity, MIS can be performed relatively and safely. However. in advanced malignant diseases which require more complex surgical manipulation, the of patients and the principles of oncologic surgery should be considered before the selection of surgical methods, MIS would be performed more and more with aid or technologic advancement. However, long-term result with equivalent oncologic outcomes to open surgery is necessary to be one of standard surgical treatments in thoracic surgery.

Effect of ultrasonic agitation on the contact properties was studied in Ni electroless plating and Pd activation. P-type Si bare wafers were used as substrate and DMAB was used as reducing agent due to its good electrical properties, solderability and compatibility to substrate. In activation, high density Pd nuclei of small size were formed during ultra-sonic agitation compared to that of no stirring. In electroless plating, the plating rate was enhanced by 30∼90% by using ultrasonic agitation. In elecrtoless plating, inhibitor is the most effective additives in ultrasonic agitation. In this experi-ment, thiourea was used as inhibitor. The less the amount of the inhibitor, the more ultrasonic agitation efficiency. It is confirmed by SEM that Ni-B films formed by ultrasonic were coarser, less porous, and denser than those of no stirring. In ultrasonic agitation, boron content of the films was more than those of no stirring. In this case, the more DMAB concentration, the higher the temperature, the less pH, the more boron content. Resistivity of the films formed by ultrasonic agitation was higher than that of no strirring. As the content of boron was increased, the resistivity of the films was increased exponentially.

This study aimed to explore EFL learners' beliefs and preferences about reading tasks and to examine the reading processes that they use for making sense of text. The subjects were comprised of 107 college students who were non-English majors and aged 19-28 years. Based on scores achieved on a reading comprehension test, they were divided into two groups (more-skilled and less-skilled readers) and asked to respond to a survey in class. The results of the survey revealed that: (1) a majority rate themselves as fair readers, which might be indicative of the insecurity they feel toward L2 reading; (2) authentic texts (especially magazines) and popular media appear to be their favorite reading materials; (3) unknown vocabulary is a major impediment to their L2 reading comprehension; (4) the more-skilled readers manifest a meaning centered view of reading, whereas the less-skilled readers center on vocabulary; and (5) both groups employ a multistrategic approach to L2 reading; however, the less-skilled readers are less successful in determining the meaning of unknown vocabulary. Pedagogical implications for EFL classroom teachers are provided.

The study is about the grading methods for the apparel CAD systems. So far the shift grading is used mostly in the industry. But the split grading has its advantage such as less data Input which is required for grading. So the research is aimed to prove that the split grading is not accurate than the shift grading and more efficient in speed, and to give the guidance of the split grading so that the split grading method can be applied in future apparel CAD systems more often. The results of the research were: 1. Split yarding produced graded patterns as accurate as shift grading. Yet split grading was more efficient and convenient because it required less data input than shift grading. 2. The 10 grading charts were grouped into 3 groups by the bust girth intervals, 3 cm grading, 4 cm grading and 5cm grading. 3. The grading areas were varied depending on the grament designs, gradre's skill and the grading intervals. 4. Guidance for the split grading was suggested.
