월경전증후군은 여성만이 경험할 수 있는 생리 전 불편감을 치료가 필요할 정도로 심각하게 느끼는 병을 말한다. 여성의 65%가 가벼운 우울감과 같은 생리 전 불편 증상을 호소하고, 20~40%는 월경 때마다 반복되는 치료가 필요한 정도의 다양한 증상으로 월경전증후군을 앓고 있다. 또한, 이들 중 2~9%는 사회적, 직업적으로 더욱 심각한 증상 때문에 치료를 받게 되는데 이를 월경 전 불쾌장애라고 부른다.

성대의 마비는 그 원인과 정도에 따라 애성, 연하장애, 호흡장애 등 다양한 기능 결손을 초래하게 되므로, 마비된 성대에 의한 불편을 외과적으로 처치하기 이전에 반드시 마비의 원인에 대한 이해와, 환자의 불편에 대한 정확한 이해가 선행되어야만 적합한 술식을 선택할 수 있다. 예를 들어 두개저수술의 합병증으로 갑자기 발생된 성대마비와 갑상선암에 의하여 서서히 진행된 성대마비의 경우 그 예후나 경과가 전혀 다른 질환이라 할 수 있기 때문이다. (중략)

This study analyzed the effects of the nutrient intake on oral health and chewing difficulty according to the age group. The subjects were 5,855 participants of the third Korea National Health and Nutrition Examination Survey(KNHANES VI), 2015, Korea Centers for Disease Control and prevention and aged 20 years and over. The data were analyzed using SPSS Ver 21.0, classified as the difficulty in chewing group (DC) and no difficulty in chewing group (NDC). As a result, the DC rates were 5 times higher in the 60+ year age group (39.5%) than in the 20-39 year age group (8.1%). The DC group were experience periodontal disease (33.4%), dental caries (30.1%), diabetes (41.8%), myocardial infarction (57.3%), arthritis (44.0%), asthma (48.0%), and depression (41.9%). In addition, 86% of the DC group were experiencing speech problems. The DC group had significantly lower intakes (1446.59g), than the NDC group (1666.62g), and the protein, carbohydrate, dietary fiber and other dietary intake were significantly lower. These findings suggest that the chewing difficulty is related to the nutrient intake, and psychological status in the elderly DC group. Therefore, the care of chewing difficulties is essential for the elderly to maintain a healthy lifestyle. Accordingly, oral care and myofunctional therapy are needed to maintain oral health.

A trial has been made to find out a new method of calculating the survival rate of a fish Population utilizing the length composition data and the characteristics of the frequency curve of the length which usually is normal distribution curve. In this paper, a stochastic method is introduced and applied to calculate the survival rate of yellow croaker caught by Korean trawlers in the Yellow Sea and the East China Sea in 1971. The results are as follows : Mean of survival rate 0.46089 Variance 0.03073 Standard deviation 0.17529 95 percent confidence interval 0.36040-0.56138.

Objective: The aim of this study was to illustrate the circumferential comfortable retainer (CCR) as a removable maxillary retainer with good potential patient compliance and to evaluate the discomfort of the retainers including distorted speech, gagging sensation and appliance discomfort. Methods: Sixty-six orthodontic patients (male, 23; female, 43; mean age, $23.42{\pm}10.19$ years) who received orthodontic treatment with fixed orthodontic appliances were randomly assigned to two groups after debonding, a conventional wraparound retainer (CWR) group that fully covers the palate with an acrylic plate and a highly polished surface, and a circumferential comfortable retainer (CCR) group which has a horseshoe shaped base plate with three folds on the anterior region. A questionnaire that had a visual analog scale (VAS) which consists of a 100-mm horizontal line with 2 end-points labeled "no discomfort" on the left and "worst discomfort" on the right, with regard to distorted speech, gagging sensation and discomfort, was administered to patients after 4 weeks of retainer wear. The Mann-Whitney test was used to test the hypothesis that there was no difference between the two retainers. Results: Comparing distorted speech and discomfort, the CCR group significantly had lower values than the CWR group ($p$ < 0.05). Comparing gagging sensation, the CCR group had lower values than the CWR group but there were no statistically significant differences between groups ($p$ = 0.146). Conclusions: In conclusion, the results suggest that the circumferential comfortable retainer (CCR) might facilitate patient compliance and thereby improve the maintenance of the fixed orthodontic treatment outcome.

The purpose of this study was to measure the effects of Oketani breast massage on breast discomfort, The amount of the breast milk, and the total protein of the breast milk in early postpartum mothers. The design was a non-equivalent control group Quasi-experiment. In the nursing intervention, The Oketani breast massage was given to the experimental group twice after giving birth, and Self Mamma Care (SMC) training was given to the control group. The collected data were analyzed by $x^2-test$ and t-test. The results of the study showed that the Oketani breast massage was more effective than the SMC-treated control group because of decreasing breast discomfort and increasing the amount of breast milk and total milk protein. Therefore, the Oketani breast massage will help early postpartum mothers more easily breastfeed. For the implication for practice, this study suggests that Oketani breast massage can be used as the effective nursing intervention that facilitates breastfeeding of early postpartum mothers in clinical practice.

This study is to suggest necessary improvements of inconvenient elements as well as the ergonomic design standard to develop disabled cars by evaluating the types of needs and observing the behavior characteristics on their car use and the survey on the complaints of the disabled drivers and their guardians in the use of disabled car. The results of this study are as follows. First, both the disabled drivers and their guardians are found to feel high inconvenience and low satisfaction with the cars they use now. Second, the disabled owner-drivers also answered in a same way as guardians. They find the most difficulty in moving the supporting equipment to get into and out of a car. Both the owner-drivers with disabilities and guardians complained of lack of handiness they face when they wear the seat belts and sitting on the seats. In view of this, a disabled car to be developed should have ergonomic design for its seats and the safety of the seatbelt as well as trouble-free supporting equipment helping them move. Third, rather than owner-drivers with handicaps, guardians expressed more difficulties and less contentment with the cars for the disabled, which is reckoned to lead to the changes of perspectives on development of cars for the disabled breaking away from existing viewpoints focusing on the accessibility to the vehicles. Fourth, both owner-drivers and guardians showed higher interests in driving and other safety and convenience measures than in using supporting equipment to get into and out of vehicles, implying that rather than the accessibility to get into and out of a car, convenience should primarily be taken into account for the design of the disabled car. Fifth, the auto-manufacturer is to give prior thought to user convenience when developing a car in practice. For this, the developer may have the disabled car users join the process of development as well as asking experts for help and participation.
