This study aimed to evaluate the effectiveness of Korean rehabilitation treatement for patients with post-TKR. The medical records of inpatients undergoing Korean rehabilitation treatment after TKR from 2016.01.01. to 2021.12.31. during the admission, were analyzed retrospectively. The effect of treatment was evaluated by using a numeric rating scale(NRS) and range of motion(ROM) of knee. Statistical analysis was done using the IBM SPSS statistics 26 program. If the period of hospitalization was within 7 days or change of NRS and ROM was not recorded properly, the case was excluded. All inpatients received acupuncture treatment, Electro-acupuncture. Soyeom pharmaco-acupuncture were used at a high rate. Blood letting cupping therapy, dry cupping therapy, Interferential Current Therapy(ICT) continuous passive motion(CPM), cryotherapy were used at a high rate. A significant improvement was noted when comparing the NRS and knee ROM results at the time of admission and discharge. Korean medical rehabilitation can be effectively used for patients who have undergone TKR, to relieve pain and enable returning to daily activities. It is expected to be helpful in future studies of post-TKR in Korean Medicine. Also It can be used for medical treatment of post-TKR in Korean Medicine Hospital and clinic. However, further research with a high level of evidence is necessary to support this finding.

In this study, Real-Time Operating System(RTOS) and 3-D collision avoidance algorithm are implemented to three different Miciro Controller Unit(MCU)s and their performances compared. We selected Microchip Technology's ATmega2560, STM's ARM Cortex-M3 and ARM Cortex-M4, because they are widely used. FreeRTOS, an open-source operating system, was also used. The 3D collision avoidance algorithm consists of the vertical and the horizontal avoidance algorithm, which is implemented using C++. The performances of the MCUs were compared with respect to used memory and calculation time. As a result, Cortex-M4’s calculation time was the fastest and ATmega2560 used least memory. 본 논문에서는 RTOS과 항공기의 3차원 충돌회피 알고리즘을 세 개의 MCU에 적용하여 각 MCU의 성능을 비교하였다. MCU는 많이 사용되는 Microchip Technology사의 ATmega2560과 STM사의 ARM Cortex-M3, ARM Cortex-M4를 선정하였으며, RTOS는 공개되어 있는 FreeRTOS를 사용하였다. 성능을 확인하기 위해 적용된 3차원 충돌회피 알고리즘은 수직회피와 수평회피를 통합한 알고리즘이며 C++로 구현하였다. MCU의 성능은 각 MCU의 사용 메모리와 계산 시간을 측정하여 비교하였다. 비교 결과 세 MCU 중, 계산 시간은 ARM Cortex-M4가 빨랐으며, ATmega2560이 적은 메모리를 사용하였다.

As a growing number of people have pet animals and veterinarians undergo consequent medical treatment for pet animals, so legal disputes are on the rise. In judging the duty of explanation as well as the duty of care by a veterinarian’s medical practice in legal action, the court analogically applies legal principles of doctor’s duty of explanation to pet owners on the grounds that veterinary practice is similar to medical practice one with its high profession and that such practice is aimed to enhance an animal’s health. The recent amendment to the Veterinarians Act has stipulated that when a veterinarian performs a treatment which he/she deems likely to cause serious harm to an animal’s life or its body and he/she fails to fulfill the duty of explanation, it can constitute a breach of law. However, there is controversy as to whether infringement of a pet owner’s self-determination right might be recognized as the same legal principles as a patient’s autonomy right like the judgment. First of all, this paper explored relevant theoretical grounds and legal interests of the doctor’s and veterinarian’s duty of explanation and then looked into the similarities and differences between the patent’s autonomy and the pet owner’s self-determination right. The fulfillment of the veterinarian’s duty of explanation is premised on the fact that pet owners are entitled to have a self-determination right as to whether an animal gets veterinary treatment or not. Unlikely, the fulfillment of the doctor’s duty of explanation is a precondition that can enable patients to have the right of self-determination as a patient, closely associated with human dignity regarding intrusion upon one’s own body, except the patient’s autonomy right of medical contracts. Although there are discrepancies in legal nature and protection scope between a patient’s autonomy and a pet owner’s self-determination right, pet owners are entitled to have the same self-determination right as a patient regarding intrusion upon a body, citing that a veterinarian’s medical treatment is similar to a doctor’s medical practice, according to such judgment. However, veterinary treatment has something to do with one’s possession; in other words, intrusion upon an animal’s body rather than a pet owner. Therefore, if a veterinarian violates the duty of explanation for its treatment, it is then appropriate that infringement is properly considered to be on the self-determination right as a consumer, not on the self-determination right as a patient. In judging the veterinarian’s duty of explanation, this paper suggests that a pet owner will be entitled to have a self-determination right as a consumer who is related to a contract made for an animal’s treatment with a veterinarian within the legal interests of protection, rather than a self-determination right as a patient regarding intrusion upon a body, by the court considering the causes and backgrounds for new regulations of duty of explanation for serious treatment, including operation, under the Veterinarians Act and discrepancies in legal nature and protection scope between a constitutional patient’s autonomy and a pet owner’s self-determination right.

1998년부터 2008년까지 낙동강 물금지점의 수질, 수리 및 기상 인자를 통해 조류발생의 주요 영향인자를 평가하고 chlorophyll-a (chl-a) 예측 모델을 도출하였다. 분석 전 데이터의 신뢰도 향상을 위해 이상치를 제거하는 전처리 과정을 수행하였다. 국내 태풍영향기간을 산정하여 태풍영향기간에 포함된 데이터는 제외를 하였고 관리도 기법을 적용하여 이상치를 제거하였다. 이후 분석과정은 Method 1과 2 두 가지 방법으로 나뉘었다. Method 1은 전처리 과정을 거친 17개 항목의 데이터를 직접 이용하여 chl-a 예측모형을 도출 하였고, Method 2는 전처리 후 주요 영향인자를 도출하여 이를 통해 모형을 개발하였다. Method 2의 상관관계 분석결과 물금지역의 chl-a에 대한 주요영향인자는 수온, pH, DO, BOD, COD, T-N, NO₃-N, PO₄-P, 유량, 유속 및 수심으로 나타났다. Method 1, 2에 의한 chl-a 회귀모형은 각각 R2 값이 0.799 및 0.790의 높은 유의성을 나타내었고 2009~2010년의 데이터로 검증하였다. Method 1에 의한 chl-a 예측모형의 training period와 validation period의 RMSE 값은 각각 20.912와 24.423으로 나타났으며 Method 2를 통한 모델은 각각 21.422 및 26.277을 나타냈다. 예측 모형 도출 결과 Method 1 및 2 모두 BOD, DO 및 PO₄-P 세 가지 인자가 주요한 역할을 한 것을 볼 때 향후 물금 지점의 조류 발생은 BOD, DO 및 PO₄-P를 중점적으로 관리할 필요가 있다고 판단된다. In this study, Chlorophyll-a (chl-a) prediction model and multiple parameters affecting algae occurrence in Mulgeum site were evaluated by statistical analysis using water quality, hydraulic and climate data at Mulgeum site (1998~2008). Before the analysis, control chart method and effect period of typhoon were adopted for improving reliability of the data. After data preprocessing step two methods were used in this study. In method 1, chl-a prediction model was developed using preprocessed data. Another model was developed by Method 2 using significant parameters affecting chl-a after data preprocessing step. As a result of correlation analysis, water temperature, pH, DO, BOD, COD, T-N, NO₃-N, PO₄-P, flow rate, flow velocity and water depth were revealed as significant multiple parameters affecting chl-a concentration. Chl-a prediction model from Method 1 and 2 showed high R2 value with 0.799 and 0.790 respectively. Validation for each prediction model was conducted with the data from 2009 to 2010. Training period and validation period of Method 1 showed 20.912 and 24.423 respectively. And Method 2 showed 21.422 and 26.277 in each period. Especially BOD, DO and PO₄-P played important role in both model. So it is considered that analysis of algae occurrence at Mulgeum site need to focus on BOD, DO and PO₄-P.

의료사고에서의 손해배상책임 ― 대법원 판례를 중심으로 ―

임지성 ( Lim Ji-sung ) 연세대학교 법학연구원 의료·과학기술과 법센터 2022 연세 의료·과학기술과 법 Vol.13 No.1

Medical demand is increasing significantly due to the rapid development of medical technology and medical level in modern society, the expansion of medical insurance, the improvement of interest in and quality of life of the people, and the extension of human life. This increase in demand for medical services eventually leads to an increase in the number of medical practices for patients by health care workers, including doctors, increasing medical accidents and resulting disputes. Although it is important for patients to recover to their daily lives and return to a stable medical environment through rapid and fair resolution of medical accidents, it is difficult for patients, who are ordinary people, to prove their negligence and causal relationship. The court is easing the burden of proof so that the liability for damages can be erased by estimating the causal relationship between medical negligence and poor results under certain standards to remedy the damage on the patient side. Even if the patient's burden of proof has been eased, the outcome of the ruling will not necessarily be guaranteed to favor the patient. If a medical dispute is resolved by a judicial method by litigation, it takes a considerable period of time to make a final decision, and in addition to financial losses such as litigation costs, mental pain during the litigation period is also great. Accordingly, outside of litigation or alternative dispute resolution (or alternative dispute resolution) in which a fair and neutral third party outside the court coordinates, arbitrates, or arbitrates the positions of both parties in a way other than a lawsuit. Representative public institutions of non-litigation dispute resolution methods to relieve victims of medical accidents in Korea include the Korea Consumer Agency under the Consumer Protection Law, and the Korea Medical Dispute Mediation and Arbitration Agency under the Medical Accident Relief and Medical Dispute Mediation Act. Through this dispute resolution organization, it is possible to resolve disputes early between the parties with fast and fair handling from the start to the end of the case and low fees. Even if both parties agree to the mediation decision, it is wise for the patient or doctor to choose an external dispute resolution method for both parties' interests before proceeding with the judicial method of litigation.

Nakdong River is one of the major river in South Korea. Downstream of this river is the intake station of big cities such as Busan. Algae occurrence in the river was one of problem for a long time. Thus, in this study, long term variation of chl-a and water quality, hydraulic and climate parameters were evaluated in winter and summer season at Mulgeum site in downstream the Nakdong River. Water quality, hydraulic and climate parameters are also used for determination of the parameters significantly affecting chl-a concentration by correlation analysis. As a result high concentration of chl-a has been appeared in winter season by bloom of diatom. Thus, control of algae occurrence at Mulgeum site in winter season is needed more than summer season. Inorganic nutrients and BOD5, pH, DO showed similar variation patterns to chl-a. The value of Hydraulic parameters were increased in summer by Monsoon season in South Korea. In this period, low concentration of chl-a was also caused by Monsoon season. With the result of correlation analysis between chl-a and the other parameters, ten parameters (BOD5, COD, DO, NO3-N, NH4-N, PO4-P, pH, discharge, water velocity and precipitation) showed significant correlation(p<0.05) in winter season. On the other hand, seven parameters (BOD5, DO, water temperature, pH, PO4-P, water velocity and water depth) showed significant correlation with chl-a in summer season. Therefore, we need to make a plan for control of algae occurrence through different significant parameters by seasonal change.
