  • Objectives: The purpose of this study was to analyze the factors affecting weight loss effect of Gamitaeumjowee-tang and to see if weight loss could be predicted using influence factors and weight loss progress. Methods: From September 2016 to March 2017, we retrospectively reviewed the medical records of 139 patients who were visited to the Korean Oriental Clinic for 3 months. We conducted a regression analysis to determine whether age, gender, initial weight, patient health questionnaire-9, heart rate variability (HRV), sleep quality, drinking habit and the medication history of weight loss affect weight loss. We found weight loss prediction equations using multiple regression analysis applying significant factors and weight loss progress. Results: Gender and initial weight had a significant effect on weight loss in all periods (P<0.001). HRV had a significant effect on primary weight loss (P<0.01). Other factors did not have any significant effect on weight loss. Using the significant factors, weight loss of each period could be predicted from 23.9% to 44.6%, and tertiary weight loss could be predicted with 76.6% using factors, primary weight loss and secondary weight loss (P<0.001). Conclusions: This study suggests that weight loss effect of Gamitaeumjowee-tang maybe be affected by influence factors and that weight loss prediction equations using them can be used for obesity treatment.

  • The sound insulation capacity of a barrier is indicated by its transmission loss. In this study, the sound transmission loss of a sound barrier filled with rice-straw particles was measured by the transfer function method and a laboratory measurement method. The results of the two measurements were compared. The transmission losses measured by the two methods were similar above a frequency of 500 Hz. The loss increased greatly upon the introduction of a plywood to the sound barrier. The results of this study are expected to be used to design sound barriers for roads.

  • This paper investigates the effect of absorption loss by a human body to the received signal strength with respect to on-body transmitting antenna positions in on-to-off wireless body area networks. This investigation is based on measurement results obtained from experiments performed on human bodies (male and female) using planar inverted-F antennas in an anechoic chamber. The total absorption loss by the human body is also presented through the SEMCAD-X simulations. Our investigation showed that the received signal strength becomes lower when the transmitting antenna is mounted at a specific position where more absorption loss is experienced. The statistical analyses of on-to-off body channel characteristics based on the measurement results are presented.

  • Large scale flood disasters bring human losses and properties, which lead to the decrease of our productive value and change social environment. Human loss and economic damage are considered to be the same system but they are viewed as separated systems. The total amount of human loss can be represented as the total amount of economic damage estimated in the frame of social system while it will be possible to make mutual changing by clearing the relations between social and economic systems. In this regard, an attempt to estimate economic loss considering per capita Gross Domestic Production (GDP) caused by flood-related mortality was carried out to the typhoon Rusa of 2002 in Kangwon-do. The proposed method tried to capture quantitative factors which are affecting the loss of per capita GDP. The approach has great importance not only to set up governmental policy but also methodological progress in the research due to impact of disaster-related mortality on GDP loss.

  • Alopecia is usually presented as patchy, no scarring hair loss. It seems to be a hormonal imbalance or an immune mediated disease, whereas genetic predisposition, environmental and psychological factors may be involved in its etiology. Many treatments of alopecia disease have been widely applied, but their side effects are also well known. The purpose of this study is to demonstrate efficacy and safety of a food supplement containing medicinal plant extracts, amino acid and vitamin complex on the prevention of hair loss in human. A total of 20 subjects aged between 29-50 years with subjective hair loss complaint were recruited for this study. Each subject took 1 g/day supplement for 3 months. 5-Scale self-assessment test, hair loss count and measurement of hair thickness were conducted to evaluate the effect of supplement on the improvement of hair loss. Subjective hair loss was decreased and hair damage and thickness were improved in self-assessment test. After 3 months of supplementation, hair loss counts were decreased (P<0.05) while hair thickness was increased(P<0.001) significantly. There was no side effect observed during the study. These results suggest that the supplement consist of medicinal plant extracts, amino acid and vitamin complex might be useful for the improvement of hair loss with no significant side effects.

  • The ergonomic human model can be considered as a tool for the evaluation of ergonomic factors in vehicle design process. The proper anthropometric data on driver's postures are needed in order to apply a human model to vehicle design. Although studies on driver's posture have been carried out for the last few decades, there are still some problems for the posture data to be applied directly to the human model due to the lack of fitness because such studies were not carried out under the conditions for the human model application. In the traditional researches, the joint angles were evaluated by the categorized data, which are not appropriate for the human model application because it is so extensive that it can not explain the posture evaluation data in detail. And the human models require whole-body posture evaluation data rather than joint evaluation data. In this study a postural evaluation function was developed not by category data but by the concept of the loss function in quality engineering. The loss was defined as the discomfort in driver's posture and measured by the magnitude estimation technique in the experiment using a seating buck. Four loss functions for the each joint - knee, hip, shoulder, and elbow were developed and a whole-body postural evaluation function was constructed by the regression analysis using these loss functions as independent factors. The developed postural evaluation function shows a good prediction power for the driver's posture discomfort in validation test. It is expected that the driver's postural evaluation function based on the loss function can be used in the human model application to the vehicle design process.

  • Recently, many nations said "yes" to human embryonic stem cell research, signing an executive order to permit funding for the research in the mame of achieving health and life of humankind. Human Embryo Research is permitted by our Bioethics & Biosafety Act. But, illegal research cannot be divorced from civil liability since it requires the destruction of eggs of fertilized eggs and personal rights of embryo-creator. After all, though we allow to do research embryo, we should control the capacity of abuse of embryo research for embryo-creator. If research violate the law(Bioethics & Biosafety Act or Civil Law, etc), it comes to a delict by pecuniary loss and non-pecuniary loss. When it comes to pecuniary loss, Human Embryo is not body but special property. Supreme Court maintained a stance that mental suffering is generally deemed as compensable for damages for the loss of property where a person's property right is invaded by a tort or non-performance of obligation. Thus, where mental suffering occurs, which cannot be compensated by recovery of property losses, the situation must be a special circumstance and the injured could claim consolation money for such losses only if the offender knew or would have known of such special circumstances(Supreme Court Decision 96Da31574 delivered on Nov, 26, 1996, etc.). That is to say, Supreme Court regards mental suffering through person's property right invaded by a tort as damages that have arisen through special circumstances. According to Civil law article 393 (2), the injured could claim consolation money for such losses only if only if the offender had foreseen or could have foreseen such circumstances. Also our court will solve through damages for non-pecuniary loss by complementary function of consolation money in that pecuniary loss could be difficult to valuate.

  • 본 논문에서는 캡슐 내시경의 무선통신이 이루어지기 위한 환경 연구와 더불어 그에 적합한 수신 안테나를 설계하였다. 제안된 안테나는 인체와 같은 multi-loss layer환경에서 전파 손실을 최소화 하고 magnetic field를 이용하기 위해 루프 안테나로 설계했다. 주파수 대역은 인체 내 전파 손실을 고려하여 $400\~500$ MHz이고 FCC 규정에 따라 인체 각각의 조직에 대한 유전율과 도전율을 추출했다. 이를 하나의 등가 모델로 설정하고 그에 따른 유전율과 도전율을 계산해서 인체를 대신할 수 있는 수용액을 제조하였다. 전파 손실이 심한 인체 내에서 캡슐이 이동함에 따라 수신 레벨이 급격히 감소하기 때문에 배열 안테나가 요구된다. 1 mW의 신호를 송신하는 송신 안테나 위치에 상관없이 배열 안테나의 신호 레벨은 평균 -60 dBm 정도로 충분한 신호 검출이 가능한 것을 확인했다.

  • Collective intelligence can be an influential factor of decision-making based on collaboration and information exchange between individuals. Our study explores whether collective intelligence can mitigate the loss aversion effect, bias and error in human judgment, and collective intelligence in online communities can reduce the loss aversion effect. Our community settings display both individual-level and group-level loss aversion effect, investigate effective collective intelligence characteristics like investment commitment, participant experience. Using a multi-method approach our research comprises a web-based experiment with 100 participants investing 3 situations from a real-world community, data from a survey measuring loss aversion behavior of participants. The results suggest the loss aversion effect mitigates under the online-circumstance. Overall, our results suggest that, while collective intelligence mitigates the loss aversion effect, participants do not transfer these results to other settings.
