정홍량,손부순 한국환경과학회 2005 한국환경과학회지 Vol.14 No.4

A survey was conducted to 890 radiological technologists working at 44 general hospitals of 16 cities and provinces across the county to determine their stress level according to regions divided into the capital city, metropolitan areas and small- and medium-sized cities. For this purpose, such factors as their working environment, role playing, job conflict and job burden were compared and analyzed according to the regions. The findings may be summed up as follows: 1. In terms of working environment, radiological technologists in the capital city were found to have the least stress(23.46), followed by those in metropolitan areas(24.53) and small- and medium-sized cities(24.85). There was a significant difference according to the regions as for the item 'worry about influence of radioactive contamination(genetic, decisive and plausible)(P<0.001 ). 2. As for role playing, radiological technologists in small-and medium-sized cities appeared to receive the highest stress(18.25) followed by metropolitan areas(17.71) and the capital city(16.69). There was a statistically significant difference(p<0.001) according to the regions 3. Regarding job conflict, those who work in small- and medium-sized cities turned out to get the highest stress(15.66) compared to those in metropolitan areas(15.35) and the capital city(14.44). In terms of job autonomy, there was no significant result from the survey in spite of the difference between metropolitan areas(14.87). small- and medium-sized cities(14.79) and the capital city(14.66). 4. Little difference was detected according to the regions as far as the job burden(excessive or too little) was concerned. But their was a significant regional difference in terms of patient-related factors with the capital city(11.50), small- and medium-sized cities(10.75), and metropolitan areas(10.63)(p<0.001).

Sn-3.5Ag 솔더 범프 플립칩의 무플럭스 열초음파 접합

洪淳珉,姜春植,鄭在弼 대한금속재료학회 2002 대한금속·재료학회지 Vol.40 No.6

The thermosonic bonding was investigated as a fluxless solder bump flip chip bonding method. The 100 ㎛-diameter Sn-3.5 mass%Ag solder bumps were formed on test flip chip by laser ball bonding process. The test flip chips were bonded to a TSM-coated glass substrate using thermosonic bonding method at different temperature, bonding load and ultrasonic power. The die shear strength was evaluated and fracture surfaces were examined with SEM. The Sn-3.5Ag solder flip chip bonding was possible at lower temperature than the melting point of the solder. The die shear strength increased with increasing bonding temperature, bonding load, and ultrasonic power. However, at excessive bonding load condition over 1.0 N/bump, the die shear strength decreased due to the fracture at UBM/ Si-chip interface. The bump height decreased with increasing bonding load but did not change with ultrasonic power.

As a result of rapid aging speed in our society, it is necessary to supply a lot of housing for older people in near future. When we think that high portion of residence in rental housing complex composed of small units is the elderly, the housing units in those apartments have to be designed for the physical, mental, social, and economical conditions of elderly people who lives in such a residential complex. Considering these living conditions of the elderly, this study proposes a remodeling prototype of a living unit for older people in rental housing complex. For the research of this topic, various characteristics of the elderly and the environmental requirements for them firstly have been analysed from the literature survey and the interviews with two residents living in a rental apartment. And the design considerations for each space of the housing unit such as entrance, living room, bed room, bath room, and so forth have been explored. Based on the design guidelines above, the remodeling plan of a housing unit for older people has been propose as a result of this study.

Caco-2 세포 단층막 투과 실험시 교반이 약물의 투과계수에 미치는 영향

홍순선,유호정,이홍,정석재,김대덕,심창구 한국약제학회 2005 Journal of Pharmaceutical Investigation Vol.35 No.2

The unstirred water layer (UWL), which has been known to exist in the boundary of the intestinal lumen and intestinal wall, often behaves as an absorption barrier especially for lipophilic drugs. The intestinal absorption of drugs is often characterized using Caco-2 cell monolayers grown on Transwell polycarbonate membranes. The permeability (Pare) of drugs across the cell monolayer might be influenced by the agitation of the donor compartment, since the width of UWL on the surface of the cell monolayer would be reduced by the agitation. In this study, the effect of agitation of the donor compartment with 60 rpm on the permeability was measured for 12 drugs with a wide range of lipophilicity and permeability. The of mannitol, tributylmethyl ammonium, cimetidine, ranitidine, hydrocortisone, benzylpenicillin and loxoprofen was not influenced by the agitation, while the P_(app) of theophylline, propranolol, YH439, phenylpropanolarnine and testosterone was increased by the agitation. There was a significant correlation between the increase of P_(app) by agitation and the lipophilicity for the compounds having P_(app) > 2 x 10^(-5) cm/sec. No correlation was observed for the difference in P_(app) by agitation and the molecular weight, or lipophilicity of the drugs. Therefore, the agitation rate of the donor compartment in the Caco-2 cell monolayer study should be carefully controlled in order to estimate Pap, reproducibly especially for iipophilic drugs.

A fluxless reflow process for solder bump flip chip package was attempted to protect environment using Ar+10%H_2 plasma. The 100 ㎛-diameter Sn-3.5 mass%Ag solder balls were bonded to 250 ㎛ pitch Cu/Ni under bump metallurgy (UBM) pads by laser ball bonding method. Then, Sn-3.5Ag solder balls were reflowed in Ar+H_2 plasma. The plasma reflow time and power conditions to show the optimum bump shear strength and shape were 40s at 100 W and 20s at 200 W. During plasma reflow, the solder bump reshaped and the crater on the top of bump disappeared. The bump shear strength increased as the Ni_3Sn_4 intetmetallic compounds formed in the initial reflow stage but began to degrease as coarse Cu-Ni-Sn ternary intermetallic compounds formed at the solder/UBM interface. As the plasma reflow time increased, the fracture mode changed from ductile fracture within the solder to the fracture at the solder/UBM interface. The off-centered bumps self-aligned to patterned UBM pads during plasma reflow.

This study was carried out to investigate the characteristics of mulberry fruit seolgidduk. Four percent additions of mulberry were evaluated as the most suitable concentration for seolgidduk, in order to improve the color of gum metal gray and sour smell. Therefore, in order to improve the preference, citric acid was added. The acidity of mulberry fruit seolgidduk increased and its pH decreased significantly by increasing amount of citric acid. The moisture content of mulberry fruit seolgidduk showed no significant difference between the groups with added citric acid and the control of group. The L value decreased as the citric acid concentration increased. Color a and b (Ed-define 'a' and 'b') values increased significantly by increasing the amount of citric acid. The hardness, cohesiveness, springiness, gumminess and brittleness decreased as the citric acid was added. From the sensory evaluation, mulberry fruit seolgidduk with 0.01% citric acid added was the most preferred in taste, chewiness and overall acceptability. These results indicated that mulberry fruit seologidduk with 0.01% citric acid added showed the best quality.
