In an attempt to establish some guidelines for psychiatric consultants who work in a general hospital setting who frequently are encountered with depressed medical inpatients, authors evaluated a few outstanding clinical characteristics of them. We discussed why these patients seek help at the internal medicine instend of seeking more than adequate help at the psychiatric service. We also tried to visualize who they are. Authors tried to suggest some specific future guidelines for those who work with this kind of patients. The subjects were consisted of 51 medical inpatients who were admitted at the Kang-Nam St. Mary’s Hospital from Apr. 1, 1983 to Jul. 31, 1984, who were seen on psychiatric consultation and were apparently suffering from clinical depression. Their clinical characteristics were compared with randomly selected 48 psychiatric inpatients with depression who were hospitalized at the same hospital for the same period. The conclusions were as follows: 1. For their age distribution, medical inpatients with depression group with age over 60(23.5%) were two times greater than psychiatric inpatients with depression group for the same age bracket (10.4%). This result shows current trend that senile depressed patients tend to seek medical help rather than to seek psychiatric help. 2. For their medical diagnostic distribution, medical inpatients with depression frequently received one of the gastrointestinal disorder diagnoses(26.6%) at the internal medicine. After psychiatric consultation, “medical diagnoses” decreased from 77.7% to 63.3% and diagnoses of “depression” increased from 6.4% to 27.6% for the medical inpatients. 3. For the depressed female medical inpatients who were seen on psychiatric consultation, marital problems were the most frequently observed psychiatric problems which needed psychiatric attention. This finding appears to reflect women’s trend to express their emotional conflicts in a more subtle and vague physical symptoms of depressive equivalents rather than outright depressed affect itself. 4. Most of the chronic dysthymic disorder patients with multiple physical complaints (62.7%) usually seek medical help rather than psychiatric help. Whe compared with this, patients who suffer from depressed affect itself rather than physical symptoms of depression came directly to psychiatric service. 5. Regarding their physical symptoms, both of the depressed medical inpatients and depressed psychiatric inpatients frequently complained of gastrointestinal symptoms, 39.9% and 41.9% respectively. For their frequency and number of physical symptoms, depressed medical inpatients complained more of them (3.76±1.70) than those of depressed psychiatric inpatients (1.73±1.94). 6. While they were admitted at the internal medicine, depressed medical inpatients frequently recieved antianxiety drugs (80.4%). However, very few of them (9.8%) recieved less than therapeutic dose of antidepressants before psychiatric consultation. After psychiatric consultation, 74.4% of the recieved antidepressant medication and 45.2% of them were followed-up by psychiatric consultants. Psychiatric diagnosis of “depression” was officially adopted on discharge summary for 44.0% of them. 7. Eventually, 80.0% of the depressed medical inpatients who were recommended transfer for psychiatric treatment were transferred to the psychiatric service for proper psychiatric treatment. However, their duration of hosptalization (23.8±14.41 days) was shorter than that of depressed psychiatric inpatients (31.21±21.91 days). These transferred depressed patients who originally seek medical help tends to discharge early as soon as their physical symptoms clear up and before gaining any insight. Those who were recommended out patient clinic followup only 14.3% of them were adequately followed up at outpatient clinic. 8. Findings of this study suggest that most of these patients could be more adequately managed by establishing a psychiatric liasion service at the gastroenterology section of internal medicine in the future.

Gas Holdup and mass transfer coefficient were measured and the effect of activity coefficeent and gas velocity on them was studied. Gas holdup increased as the gas velocity increased, and decreased as the concentration of aqueous solutions of NaCl-KCl increased Mass transfer coefficient increased as the gas velocity increased, and decreased as the concentration of aqueous solutions if NaCl-KCl increased. Correlation equation between the gas holdup and mass transfer coefficient, and the various factors is shows a good agreement with experimental values.

유지보수를 위한 프로그램의 복잡도 측정 요소

류성열,이성은,안재홍 崇實大學校 生産技術硏究所 1996 論文集 Vol.26 No.2

70년대 이후 프로그램의 복잡도를 측정하는 척도들이 꾸준하게 연구되어져 프로그램의 크기, 데이터, 제어 등의 부분적 요소를 통하여 프로그램의 복잡도를 측정할 수 있게 됐다. 그러나 대부분이 부분적인 요소를 통한 전체 프로그램의 측정에 초점이 맞추어져 있으며 유지보수의 특성에 관한 부분은 고려되지 않고 있는 실정이다. 프로그램의 유지보수를 위해서는 무엇보다 프로그램의 완벽한 이해가 선행되어야 한다. 따라서 프로그램의 유지보수에 대한 일정이나 비용등을 예측하기 위해서는 대상 프로그램을 이해하는데 얼마나 어려움이 있는가에 대한 척도가 필요하다. 본 논문에서는 유지보수시에 프로그램의 복잡도에 관한 측정에 이용될 수 있는 요소들을 추출하고 그 요소들이 척도로서 활용될수 있는 방안에 대하여 연구하였다. 프로그램의 복잡도 측정 요소로는 기존에 프로그램의 복잡도에 관한 측정에 활용되던 크기, 데이터, 제어요소 보다는 모듈간의 결합관계, 유지보수시 필수적으로 이해가 요구되는 중요 모듈들, 프로그램의 직접적인 이해를 가져올 주석 등을 이용하였다.

The friction losses of an internal combustion engine represents the difference between indicated horse power and brake horse power, and known to be caused by the friction between the piston ring and cylinder wall, bearing friction, and losses to the other parts of machine, etc.. The factors which affects on friction horse power are assumed as gas pressure in the cylinder, piston velocity, stroke bore ratio and oil viscosity. To investigate these major effects a series of experiments were taken by testing 3 kinds of spark ignition engines which were arbitrarilly chosen. in addition to this, a study about the pressure distribution of oil film formed between piston ring and cylinder wall which occupies most parts of friction horse power was performed to estimate the state of lubrication between the piston ring and cylinder wall. The results are as follows; 1) It was observed that the effect of gas pressure in the cylinder to the friction horse power of the engine was varied according to piston velocity, by large extent in low velocity and little in high velocity. 2) The effect of engine design to the friction horse power was constant throughout all the range of piston velocity and the fact that large stroke bore ratio engine has greater friction horse power than the small one was also observed. 3) As to the effect of piston velocity to the friction horse power, It was observed that the friction horse power increased as the piston velocity increased; for 10% increase of piston velocity, the increased ratio of friction horse power was about 14.2%. 4) As to the effect of oil viscosity to the friction horse power, it was ascertained that the oil viscosity was given a proper change the friction horse power changed accordingly; for 10% change in oil viscosity, the amounts of change in friction horse power was about 7.2%. 5) In the process of calculating the distribution of pressure in oil film formed between the piston ring and the cylinder wall, it was observed that the peak point of the pressure appeared at the distance of 0.05cm from the ring edge, and the crank angel where the maximum pressure point appeared after top center was 80 degrees.

Ethanol 물 混合溶媒中에서 食品保存劑의 電氣傳導度에 관한 硏究

尹庠基,朴鍾烈 東亞大學校 大學院 1979 大學院論文集 Vol.3 No.-

The conductance measurements are carried out for four species of the food preservatives : potassium sorbate, sodium benzoate, sodium dehydroacetate and salicylic acid in various compositions(wt. %) of ethanol-water mixtures at 25℃ for the concentration range 10-2 to 10-3M. The plots of equivalent conductances(Λ) vs. concentration(??) for the salts of preservatives except salicylic acid which is uniquely weak acid above all are showed good linearity, while limiting equivalent conductances (Λ.) for all salts in common decrease with increasing alcohol concentration(wt. %) and show minimum value at and near 50% solvent mixtures. Considerable decrement in Λ. are observed for all salts as going to pure water side. These behaviors mentioned above are interpreted in terms of the microscopic structural change of water in alcohol-water mixtures. Abnormal conductance behaviors are found for salicylic acid as indicating anomalously greater value of Λ. than others and continuous decrease in Λ. with increasing of wt. % alcohol without showing any minimum behavior.

氣泡塔內에서 竝流 물-알코올-無機酸 溶液中의 가스홀드엎에 관한 硏究

金相烈,李成植 동아대학교 공과대학 부설 한국자원개발연구소 1983 硏究報告 Vol.7 No.1

We have studied gas holdup according to gas velocity, liquid velocity, and properties of solution such as surface tension, viscosity, activity coefficient and density in cocurrent bubble column. The results are as follows; 1. As liquid velocity increases under the large gas velocity, gas holdup decreases to some degree but at slow gas velocity it is not nearly affected. 2. If surface tension of solution grows, gas hold up drops. This phenomena was remarkably appeared in three components mixture solutions of water-methanol-inorganic acid. 3. Gas holdup with a increase of viscosity of solutions rises gradually in 3 solutions of water-ethanol-inorganic acid, but in case of solutions of water-methanol-inorganic acid it grows in the range of the small value and reduces rather in the large value. 4. The correlation among the gas holdup and physical parameters was formulated from experimental data as follows; φ=k(DU_(G)ρ_(G)/μ_(G))ⁿ (σ/g^(½)μ_(L)δ^(½)ε) K and n are the same as Table 1.
