Electropulsing Treatment on Enhancement of Electrical Conductivity of Screen-Printed Ag Wire

Ju‑Won Park,Howook Choi,Hwangsun Kim,Simoon Sung,Hye‑Jin Jeong,Il Kim,Jaeseok Gong,Sung‑Tae Hong,Heung Nam Han 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.5

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.

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.

이주여성 가사노동자에 관한 이론적 재검토

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.

The combustion characteristics of vehicle upholsteries

Park,Hyung-Ju,Kang,Young-Goo,Kim,Hong 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-

Five parts of vehicle upholsteries were sampled to determine its combustion characteristics. Oxygen Indexer, Smoke chamber, Differential Scanning Calorimetry(DSC) are applied as the analysis apparatus. All LOI values of samples appear less than 21. The combustion phenomena of vehicle upholster primarily depends on properties of each layer material. The amount of smoke generated is the experiment reached the maximum value within 30-90sec after ignition. The experimental results of combustion characteristics and DSC of H/Line also indicated that the layer of foam was melt first and it caused the propagation of flame through the sample. The combustion characteristics of multi layer materials primarily depend on thermal characteristic of single layer material.

The political policies between the two Koreas since the Korean War have resulted in exclusive senses and this aspect affected to politics, society, education and so forth over the last half century or so. Those affected exclusiveness recently appears in sport too, therefore the sports exchanges between the two nations has now almost disappeared from the scene under the modern and present political conflicts. As witnessed in the case of Germany, sports exchanges can play enormously important role to achieve unification of the two Koreas. It was the research intention to understand the transformation of sports policies in two Koreas and to explore changes of sports exchange since the Korean War. The main purpose of the study, therefore is to find out appropriate approaches to the sports exchange towards the two divided Koreas. An inter-subjective discussion has been made analyzing primary and secondary sources. The research outcome are as follows. Firstly, the President Chung Hee Park attempted sport exchange with the North intending nationalistic oriented policy and it was aimed to focus on elites' intensive cultivation considering winning always against the North. This could not accelerated active exchanges moreover, it in fact hindered the exchanges with the North. Secondly, the President Doo Hwan Jeon announced 'national conciliation and democratic unification' and he intended to promote unification policy during his reign. However, the military based government had a limit to continue the policy towards the unification through sport. Moreover, the international politics during the early 80s was in the Cold War and the Korean situation was influenced. Thirdly, during the reign of Dae-jung Kim, his intention towards the unification was often criticized due to various concerns including the misuses of supported material. However, his Sunshine Policy to embrace the North in fact contributed to an active sports exchange between the two Koreas. Various types of competitions and sports events were taken place constantly promoting the national homogeneity. Overall research discussion and result may be able to contribute to finding sound methods to conciliate and to express the Korean national homogeneity in the global society. Therefore relevant researches needs to be carried out for an appropriate way of sports exchange and it may be expected that the sports exchanges will be setting a strong stone for the democratic unification in the near future.

The purpose of this study was to assess the soft tissue changes using twenty skeletal class Ⅲ malocclusion patients who treated with bimaxillary surgery for the correction of dentofacial deformities. Patients were devided into two groups. One was impaction and advancement of maxilla with mandibular set-back (Group 1), the other was downward and advancement of maxilla with mandibular set-back (Group 2). Preoperative and postoperative one year cephalometric data were analyzed and compared. Results obtained were as follows : 1. The ratio of horizontal changes of soft tissue to hard tissue at Nt to ANS, Ls to UI, Li to LI, sPog to Pog were 1:0.60, 1:0.79, 1:0.47, 1:0.63 in group 1 respectively, and 1:0.59, 1:0.48, 1:0.83 1:1.09 in group 2 respectively. There were highly predictable in upper lip, lower lip, and chin. 2. The ratio of vertical changes of soft tissue to hard tissue at Nt to ANS, Li to LI were 1:0.72, 1:0.06 in group 1, and others showed no statistically significant differences. 3. The ratio of horizontal changes of Ls to hard tissue movements at LI(h) was 1:-0.82 in group 1 and at UI(h), LI(h) were 1:0.48, 1:0.01 in group 2. These ratios of group 1 were greater than those of in group 2. 4. The direction of horizontal change of Li was the same as that of hard tissue change. The ratio of horizontal changes of Li to LI was 1:0.47 in group 1 and others showed no statistically significant difference. 5. The changes of upper lip thickness and length were -1.6 mm, -1.4 mm in group 1, and -1 mm, -2.7 mm in group 2. 6. The ratios of thickness of upper lip to ANS, Ul, LI were 1:-0.83, 1:-0.37, 1:0.11 in group 1. There was similar trend in group 2, but there were no statistically significant difference. These results suggest that prediction of changes in soft tissue of upper lip, lower lip, and chin were 79%, 47%,and 63% in group 1, and 48%, 83%, and 109% in group 2 after bimaxillary surgery. There was a tendency of decrease in thickness and increase in length of the upper lip.

Various combinations of cut rose and other cut flowers were accomplished to provide basic data for vase life extension of cut rose. The vase life of cut rose combined with other cut flowers was as follows ;rose (8 days) > rose + gladiolus (6 days) > rose + calla (4 days) > rose + chrysanthemum (4 days) > rose + carnation (3 days) > rose + gerbera (2 days). The vase solution of cut rose without other cut flowers had the lowest concentration (1.2×105 CFU/mL) of bacterial cells. On the other hand, The vase solution of cut rose with gerbera had the highest concentration (9.3×106 CFU/mL) of bacterial cells. From the above results, it is concluded that vase life of cut rose is extended by reducing the bacterial cells in the vase solution though the proper combination with effective cut flowers.
