The purpose of this study was to evaluate the influence of three dentin bonding agents on the shear bond strength, microleakage, and film thickness of resin cement for porcelain laminate veneer. Dentin & enamel surfaces were treated with three dentin bonding agents such as Scotchbond 2. All Bone 2, and Prisma Universal Bold 2 and were cemented by G-Cera cement for porcelain laminate veneer. For bond strength test, the specimens were stored in 37℃, 100% humidity for 48 hours and shear bond strength was measured with Instron testing machine (model no. 4201) at crosshead speed of 1.0mm/min. For microleakage and film thickness measurement, the specimens were stored in 37℃, 100% humidity for 7 days, thermocycled for 1000 cycles. Microleakage and film thickness of resin cement were measured with inverted metallurgical microscope(PME 311, Olympus, Japan). The results were as follows : 1. The shear bond strength of resin cement for porcelain laminate veneer to dentin was enhanced by the use of dentin bonding agent and All Bond 2 were effective in improving the shear bond strength to both enamel and dentin. 2. All Bond 2 were effective in reducing microleakage of veneers bonded to dentin, approximately to the same degree to the veneers bonded to enamel. But Prisma Universal Bond 2 and Scotchbond 2 failed to limit microleakage at the gingival margin of veneers bonded to dentin. 3. the 40% phosphoric acid in G-Cera system and the 10% phosphoric acid in All Bond 2 appeard equally effective in reducing microleakage of veneers bonded to enamel. 4. There were no significant increase in cement film thickness when using Prisma Universal Bold 2 or Scotchbond 2, but with All Bond 2 slight increase in the cement film thickness were present.

Providing activities with appropriate length is as important for young children’s learning as what is taught. In order to understand teachers' perceptions of the appropriate length of the school day, the study conducted a survey of 149 public and private kindergarten teachers in Korea. As for the length of the school day, kindergarten teachers perceived that 3 hours 16 minutes for 3 year olds, 3 hours 54 minutes for 4 year olds, and 4 hours 24 minutes for 5 year olds were appropriate. Public kindergarten teachers tended to perceive a shorter school day than private kindergarten teachers and teachers in mixed age group classes perceived a longer school day compared to the single age group teachers. Most teachers responded that 30 minutes is an appropriate length for a class period. As for the question regarding areas emphasized for each age group when organizing the curriculum according to the number of hours per lesson, the most frequent answer was to emphasize physical education and health for 3-year olds, social relationships for 4-year olds, and communication for 5-year olds. The findings of this study provide implications for including the appropriate length of the school day and hours of instruction in future curriculum revisions.

The purposes of this study were to assess the child care centers' foodservice facility, and to develop the kitchen facility model based on the general sanitation standards and guidelines in order to provide basic information for a plan review to build or renovate child care centers' foodservice facility. The scopes of the study include : 1) field assessment of the foodservice management practices and facilities in 8 public child care centers, and 2 private child care centers which they are subsidized from the government as public child care centers, 2) development of child care centers' kitchen facility model based on the General Sanitation Standards and Guidelines. The results of this study can be summarized as follows : 1. Field Assessment of the Child Care Centers' Foodservice Facility Average number of children in child care centers was 78.0±24.20, the average space of kitchen was 15.13±4.25(㎡), Especially, the average space of kitchen was 18.49±4.35(㎡) with enrollment capacity of 90∼120 children in child care centers. The inventory level of most foods was relatively low except rice and kimchi. Kitchen facilities and equipments were similar to those of home kitchen and did not meet the standards of institutional practice. Therefore, the director in child care centers should recognize the importance of the sanitation management and pay more attention to the renovation of foodservice facilities as well as sanitation management practices. 2. Development of the Kitchen Facility Model based on the General Sanitation Standards and Guidelines The kitchen facility plan model with enrollment capacity of 100 children was developed based on the results of field assessment and literature review. Suggested kitchen space was 34.16㎡(6,100mm×5,600mm). This space was bigger than the results of field survey or precedent study, considered appropriate to implement the general sanitation standards. The main feature of the developed kitchen facility plan and model was product flow in one direction from the arrival of the raw material to the finished product in order to prevent cross contamination and to improve working efficiency.

Developmental anomalies arising from the branchial apparatus include cysts, external sinuses, internal sinuses, and complete fistulas. Second branchial cleft cysts are by far the most common among these anomalies. It may occur at any age, being most common in the third decade, and more frequent in the male than in the female. It usually presents a smooth, round, nontender fluctuant mass located between the level of the tragus and the clavicle along the anteromedial border of the sternocleidomastoid muscle. It is lined by respiratory or squamous epithelium unless inflammation is present. The considerable amount of lymphoid tissue may be found beneath the epithelium. The treatment of choice of branchial cleft cyst is surgical excision. If the lesion is acutely infected, however, it is essential to relieve the infection prior to the surgery This report deals with two cases of second branchial cleft cyst. In case 1, the cyst had rapidly increased in size over pregnant period. In case 2, the patient presented the swelling in the left neck, and had the history of incision and drainage because of misdiagnosis as submandibular space abscess. The infection was treated by antibiotic therapy in the first place, and then complete surgical excision was made. There was no evidence of any recurrence or complications for these 3∼4 years.

The effect of high electric current density on the sintering of Ag wires manufactured by screen printing is evaluated throughelectrical resistivity analysis and microstructure observation. Different forms (continuous and pulsed) of electric currentwith different current densities are applied to the specimens. Conventional heat treatment is also performed as a controlgroup to examine the athermal effect of electropulsing treatment. Compared to the conventional heat treatment, the resistivityis reduced more under the electropulsing treatment with continuous current for the same temperature and treatment time.Also, the process time of electropulsing treatment can be reduced by applying a pulse form of high density current insteadof continuous current without losing the benefit of enhanced reduction of resistivity. The microstructural observationsobtained from high angle annular dark field scanning transmission electron microscope and a digital precession instrumentclearly show that necking connecting the crystals is formed more firmly under electric current. In addition, the temperaturechange of Ag wire and substrate is calculated according to the change of the resistivity when the electric current is appliedto confirm the reliability.

이주여성 가사노동자에 관한 이론적 재검토

박홍주 동덕여자대학교 한국여성연구소 2009 젠더연구 Vol.- No.14

This study examined the pre-studies of labor situation of migrant domestic workers from a feminist viewpoint. Migrant women's domestic service labor is a representative case showing that the patriarchal gender division of labor in which women take a full burden of care is restructured into division of labor among women on the basis of race, nationality and age in the era of transnational migrant labor. It is also a starting point for criticizing Korean policies on migrant labor that fails to reflect the realities of 'Asian migrant women' as a new phenomenon that removes or expands the boundary of family in the age of globalization. Furthermore, this is a practical work that analyzes the migrant women's human rights.
