Cheol Won Hyeon,Won Lee,So Yoon Kim,Ji Yong Park,Su Hwan Shin 대한내과학회 2020 The Korean Journal of Internal Medicine Vol.35 No.3

Background/Aims: Possible fatal complications arising from coronary angiography (CAG), percutaneous coronary intervention (PCI), and coronary artery disease itself, are likely to cause medical disputes. Presenting the current status and reasons for judgments given in lawsuits related to CAG/PCI, this study aimed to identify ways to prevent unnecessary disputes and medical malpractice suits related to CAG/PCI through lawsuit analysis. Methods: A total of 13 cases (20 judgments) found in the Supreme Court of Korea’s Written Judgment Management System from 1998 to 2017 were analyzed. Results: Coronary artery injury was the most common causative complication that led to lawsuits (n = 6, 46%). Six cases (46%) were ruled in favor of the plaintiff for violation of duty of care (n = 4) and duty of explanation (n = 2), respectively. Cases that violated duty of care included two errors in intra-procedure device manipulation, one in pre-procedure diagnosis, and one in management of post-procedure complication. Lack of explanation regarding the risk of complications was pointed out in both cases that violated duty of explanation. The average awarded amount for the damages was 114,436,064 Korean won. Conclusions: Physicians need not fear unfair judgments so long as they follow standard of care because the Court consistently looked at the probability, the foreseeability, and the evidence. Therefore, maintaining standard of care is important. Besides, specific, detailed, and comprehensible explanations, including the risk of complications in addition to the necessity of procedures, are important to ensure the patient clearly understands the possible risk of adverse outcomes.

Purpose: Through the analysis of orthopedics lawsuit rulings, the purpose of this study is to understand the current trends of medical lawsuits in orthopedics in Korea. Materials and Methods: An analysis of medical lawsuits in orthopedics was conducted. As the study method, a quantitative analysis was performed on 341 cases. Results: The average period of lawsuits, from the occurrence of the medical accident to end of the ruling, took an average of 4.22 years. The most frequent procedure that was the main cause of the medical accidents was surgery, at 46.3%. When surgery is the main procedure that caused the medical accidents, the result of examining the types of surgeries showed that spine surgery had the highest percentage. For the outcome of the accident, the highest number of cases resulted in disability and for the final court outcome, 40.5% ruled partially in favor of the plaintiff (the patient) with acknowledgement of only the damage incurred due to medical error of the total sum claimed, and dismissal of the claim made by the plaintiff (patient) accounted for 34.3%; 26.1% of cases develop infection. For the amount of claim for damage, the average amount of claim was 181,998,036 won; in the judgement amount, the average amount of judgement was 58,897,161 won. Conclusion: The most frequent procedure in orthopedics was surgery and spine surgery comprised a large proportion of these surgeries. Future studies to determine root causes of medical accidents should be conducted to reduce medical lawsuits and to plan against the repeating of medical accidents.

An analysis in heating effects of an electric radiator located in a 1-2W type chrysanthemum (3 cultivars) cultivation greenhouse installed in Gyeongsang National University drew the following conclusions. During the experiment period, the highest, average, and the lowest outside temperatures were in the ranges of -3.8~21.3℃, -5.2~16.1℃ and -12.5~14.4℃, respectively, and the average relative humidity inside and outside the greenhouses were in the ranges of 43.5~98.6% and 35.2~100%, respectively. From mid-December to early February, the lowest outside temperature was recorded as approximately -5.0~-10.0℃, which showed that it tended to be relatively lower than the temperatures recorded at the Jinju Meteorological Observatory. During the night, the leaf temperature measured directly under the radiator tended to be higher by 2~3℃ than that those at the middle point of the radiator, or higher by anegligible amount. In the case of root zone temperature, it was found that there was almost no difference between temperatures of the part directly under and the middle point, and the time when the highest temperature of root zone and other highest temperatures took place showed that there was about a 2-hour delay phenomenon. The total electricity consumption, energy supply and total heating cost during the experiment period were 2,800 kWh, 2,408,000 kcal and 112,000 won, respectively. When diesel, a kind of fossil fuel, was used as heating oil, the total heating cost was around 224,500 won. It was estimated that the total heating cost could be reduced by around 50% if a radiator was used.

The purpose of this study is to develop an air-passing soundproofing panel with more improved structure to reduce the CO2 emission and installation cost. To reduce the emission of CO2 ; it is suggested to choose low CO2 emission material relative to the aluminum and to reduce the materials by developing a specially designed air-passing soundproofing panel structure. First of all, we performed the flow analysis to predict the wind pressure according to the open angle of the air-passing soundproofing panel and the noise level analysis at the receiver point. To verify the simulation, a prototype of the soundproofing panel was made. The flow test in the wind tunnel and load test were performed. The economic evaluation for the installation of the air-passing soundproofing panel was performed and specifications of the installation was prepared. As the results of this research, it was verified that the wind load was reduced about 40% to that of the conventional one at 25m/s wind speed in the wind tunnel test. By applying the 4m span soundproofing wall with air-passing soundproofing panel and under the cost of 250 thousand won/m2 instead of the conventional 2m span panel, the installation cost will always be lowered than the conventional one in the combination of (60:40~50:50) conventional to air-passing soundproofing panel from the economic evaluation. The 20% reduction of CO2 was found by changing the 50% of aluminum soundproof panel to air-passing soundproofing panel.

Jin Tae Hong, Dohee Won1, Mi Hee Park, Sun Mi Kown, Miran Jo, Sang-Yoon Nam, Beom Jun Lee, Young Won Yun, Ki-Wan Oh, Sang Bae Han 충북대학교 동물의학연구소 2011 Journal of Biomedical and Translational Research Vol.12 No.4

The objective of this study was to determine the effect of macrophages on growth of human colon cancer cells. The results showed that co-culture of colon cancer cells with macrophages inhibited the growth of colon cancer cells (HCT116 and SW620) depending on the number of macrophages, RAW 264.7 cells, and activated THP-1 cells accompanied by down regulation of pSTAT3 in cancer cells. We also found that expression and release of cancer cell growth inhibitory cytokines, IL-1 receptor antagonist (IL-1ra) and IL-10, was increased in macrophages. Blocking of the STAT3 pathway with specific inhibitor and siRNA of STAT3 abolished the growth of colon cancer cells and expression of IL-1ra and IL-10. In addition, neutralization of IL-1ra and IL-10 with antibodies resulted in reversal of macrophage-induced inhibition of cancer cell growth. These data showed that IL-1ra and IL-10 released from macrophages inhibit growth of colon cancer cells through inhibition of the STAT3 pathway

In the second quarter of 2017, the size of the household debts has been reaching 1,388 trillion won. And, because the size of the housing mortgage loans has been closing in upon 560 trillion won, around 40.3% has been crowded in the housing demand funds. Regarding this, there is no choice but for the influence on the entire economy to be high according to the increase of the delinquency rate in case the economy worsens or the recession continues. This study intends to suggest the implications regarding the housing mortgage loans in the long-term viewpoint through the influence evaluations of the macroeconomic variables related to such housing mortgage loan delinquencies. The macroeconomic variables that were used were the housing mortgage loan delinquency rate (TOD), the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), the monetary amount of the housing mortgage loans (HML), the amount of the apartment transactions (TRADE), and these were unfolded in the viewpoint of the relationship with the real estate market and the currency policy. As a result of the unit root test, it appeared that, regarding the amount of the apartment transactions, the time series raw data had been maintaining the stability. And it was able to find out that the data of the remaining variables, including the housing mortgage loan delinquency rate (TOD), had been getting stabilized through the primary difference. Because, as a result of a co-integration test, at least 6 variables possess the linear, the selection of the model used the VEC model, and, regarding the optimal differential, the 1st model was selected based on the SC (Schwarz Criterion) value. As a result of taking a look at the granger causality relationship, it appeared that the variables that had the influences on the housing mortgage loan delinquency rate were the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), and the amount of the apartment transactions (TRADE). As a result of analyzing the VECM (Vector error correction Model) short-run equilibrium relationship, it appeared that the housing mortgage loan delinquency rate were influenced by the index of the average price of the buying and selling of the real transactions of the apartments and by the index of industrial products. As a result of a reaction to a shock, the positive (+) correlation appeared between the housing mortgage loan delinquency rate and the amount of the transactions of the apartments (TRADE) and, also, the interest rate of the new housing mortgage loan (HINTEREST). Eventually, regarding the housing mortgage loan delinquency rate, if the interest rate goes up, right away, an increase of the delinquency rate takes place. And, it appeared that, if the monetary amount of the housing mortgage loan becomes big, the delinquency rate decreases. This is because the delinquency rate has the influences on the incomes and others of the like, it can be under the control of the interest rate policies. The meaning of this research is that it investigated about the relationship with the housing mortgage loan delinquency rates by considering the indices in the real estate market and the currency policies at the same time. And, it is that, in the condition in which the scale of the housing mortgage loan having become big at present, raising the interest rate can aggravate the confusion more in the market. As a result, with regard to the proceeding with the real estate policies, the prudent and macroscopic approach is needed. And the researches on the relationships of the indices will be needed more in the macroscopic viewpoint.
