Purpose: The purpose of this study was to investigate factors influencing dysmenorrhea in middle school girls and to analyze the differences in dysmenorrhea according to personal factors of the subjects. Methods: This study was conducted from March 22 to April 2, 2010. The subjects of the study were 572 girls who attended three middle schools in Seoul and experienced dysmenorrheal. All were surveyed using the same questionnaire. Data were analyzed by the SPSS/WIN 12.0 program and included descriptive statistics, ANOVA and multiple regression analysis. Results: 1) The mean age of the subjects was 13.53 years, and the mean age of first menstruation (menarche) was 11.94 years. The number of days between the onset of menstrual cycles was 30.01 days. Most of the respondents had irregular menstrual cycles and menstrual periods lasting 3 to 7 days long. 2) Chief menstrual pains were lower abdominal and back pain. Subjects reported experiencing severe lower abdominal and/or back pain, most commonly on the second day of menstruation. The average score of menstrual discomfort was over 60 points (63%). The average score per 6 points of dysmenorrhea was as follows: fatigue (3.48), sensitivity (3.27), disability of movement (3.27), napping or lying down (2.98), mood swings (2.95), interference with studies (2.87). 3) Individual subject characteristics influencing the onset of dysmenorrhea were as follows: high stress levels, being in poor health, having an irregular diet, being younger and having longer menstrual periods than most other subjects. Conclusion: During puberty, girls with earlier menarche complained of physical and emotional discomfort, and irregular menstrual periods. Therefore, we need to explain overall menstrual characteristics and individual differences in the occurrence of dysmenorrhea, in health education programs.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had significant physical and psychological impacts on registered nurses (RNs). This study aimed to identify long COVID symptoms and their associated factors specifically among RNs. Methods: This descriptive correlational study's sample comprised 189 nurses (31.57±5.98 years, 93.7% female) in Korea. Self-reported long COVID symptoms were assessed using the COVID-19 Yorkshire Rehabilitation Scale. Data were collected from December 31, 2022, to January 13, 2023, using the online survey method and were analyzed using independent t-test, Wilcoxon signed-rank test, one-way ANOVA, Pearson's correlation, and a multiple linear regression analysis with the IBM SPSS Statistics 26.0 program. Results: A total of 179 participants (94.7%) experienced one or more long COVID symptoms. The most prevalent symptoms were weakness (77.8%), fatigue (68.3%), breathlessness (67.7%), cough/throat sensitivity/voice change (50.3%), and sleep problems (50.3%). The factors related to long COVID symptoms were marital status, type of institution, working time, acute COVID-19 symptoms, and vaccination status. The quarantine period (β=.26, p<.001) and the nursing workforce after COVID-19 (β=-.17, p=.018) were significantly associated with long COVID symptoms (Adjusted R² =.33). Conclusion: Providing comprehensive recognition is necessary for the understanding of long COVID symptoms and their associated factors among nurses and could promote a long COVID symptom management education program targeted at nurses. Moreover, it could facilitate effective nursing care and education plans for long COVID patients.

The study subjects in this study are 295 workers who work on one electronics industry, and they were composed of 93 VDT and 202 non-VDT workers. This study was carried out to obtain the prevalence of subjective symptoms and to compare psychological symptom scores from SCL-90-R between VDT and non-VDT work groups. And to verify the relationship between VDT work related symptoms and psychological symptoms, the author compared SCL-90-R T scores between symptom complaining and non-complaining groups. The results are summarized as follows : 1. Throughout the prevalence study of VDT work related symptoms according to VDT work state, the author could select the final 10 symptoms by sex;'eye fatigue', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'light headedness', 'dizziness', 'acne', 'itching sensation on face', 'difficulty in concentration', 'memory disturbance' in males, and 'blurred vision', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'abdominal distention', 'indigestion', 'acne', 'prickling sensation on face', 'difficulty in concentration', 'memory disturbance' in females. 2. Throughout comparison of psychological symptom scores from SCL-90-R between VDT and non-VDT workers, except 'Interpersonal sensitivity' in female, Mean T score were higher in VDT workers, but not significantly different between the two groups. These results indicate that the relation between VDT work status and psychological symptoms are not strongly correlated. 3. Because of the nonspecific characteristics of VDT work related symptoms, from the 40 subjective symptoms, the author selected the final 10 symptoms by sex, especially correlated to VDT, and divided the study subjects into symptom complaining and non-complaining groups. The mean SCL-90-R T scores between the two groups were compared. Except for the opthalmologic symptoms in females, the scores were significantly different between the two groups in all symptoms. And this indicates that the VDT work related symptoms strongly correlated with the present individual psychological conditions. 4. Due to understand that which of the 9 psychological symptom dimensions are strongly correlated with the subjective symptoms, the author excuted muliple logistic regression analysis, and the result were as follows; 'depression' and 'somatization', in male, and 'obsessive-compulsive' and 'somatization' in female.

The main purpose of this study is to develop a ratio scale measuring level of pain using Korean pain terms. The specific purposes of this study are to identify the degree of pain of each pain term in each subclass: to classify each subclass in terms of dimensions of pain; and to analyze factors of the Korean pain ratio scale clustering together. One hundred an4 fifty eight pain terms which were originally identified as representative terms and their synonyms were used for data collection. Fifty eight nursing professors ana sixty one medical doctors who have contacted with patients having pain were asked to rate the weight of each pain term on a visual analogue scale. Subclasses in which ranks of pain terms were same f s findings in two previous studies were 1) thermal 3 am 2) cavity pressure, 3) single stimulating pain, 4) radiation pain. and 5) chemical pain. Subclasses in which ranks of pain terms were confused were 1) incisive pressure, and 2) cold pain. Subclasses in which one new pain term was added were 1) inflammatory-repeated pain, 2) punctuate pressure, 3) constrictive pressure, 4) fatigue-related pressure, and 5) suffering-relate4 pain. Subclasses in which two new pain terms were added were 1) traction pressure, 2) peripheral nerve pain, 3) dull pain, 4) pulsation-related pain, 5) digestion-related pain, 6) tract pain, and 7) punishment-related pain. Subclass in which 3 new pain terms were included was fear-related pain. Rating scores of 5 words in 4 subclasses were significantly different between the normal group and the extreme group of subjects in terms of subjective rating. Only one word among 6 words was that newly added to the scale. Rating scores of 12 words in 9 subclasses were significantly different between doctor group and nursing professor group. Among these 12 words, only 3 were those newly added to the scale. In comparison of these 12 words, mean scores of the nursing professors were always 7 to 16 points higher than those of the medical doctors. In the analysis of judgement of subjects in terms of dimensions of pain terms, subclasses of dull pain, cavity pressure, tract pain and cold pain were suggested to be included in the miscellaneous dimension. As a result of factor analysis of the ratings given to 96 pain words using principal components analysis without iteration and with varimax rotation limiting the number of factors to 4, factors of severe pain (factor I) mild-moderate pain (factor II) , causative pain (factor III) and temperature-related pain(factor IV) were extracted with the factor loading above 0.388. When the pain words were re-arranged on the bases of factor loading above 0.368, number of factors decreased to only first two factors. Maximum score of pain word in factor II was 46.17 and the minimum score of the factor I was 45.36. Further studies are needed to identify the validity, reliability, sensitivity and practicability of this ratio scale using patients having various sources of pain.

The explosion of the aging population is changing the social environment of today's older people. Traditionally in Korea, a large percentage(over 90%) of elderly parents have lived with their married first son. But today, the number of elderly who live with their married sons has decreased(65.6%) The number of those who live in a different situation such as with their married daughter, unmarried offspring, with a spouse or alone has increased (34.4%) We can expect that the number of the elderly who have to live in institution will increase. The objective of this investigation was to determine differences in the number of health Complaints of older people according to their living situation with a view to planning more effective health care. The sample consisted of 231 persons over 65 years of age, 60 living in an Old Age Home ana 171 living in their own home in Kwangju. Data were gathered from July 9 to 26, 1983 by nursing students using a Questionnaire which was a modified form of the Cornell Medical Index. The data were categorized according to the subjects, living, sex, educational level, previous occupation, hobbies and sexual activity. The date were analyzed for statistical significant differences using F and X²tests. findings included the following: 1. There was a higher number of health complaints from persons who live in the institution than those living at home, but the difference was not significant. 2. The highest number of health Complaints were from persons who live alone, followed by those living with their daughters, and then by those living in the institution. Persons who live with their sons had the least Complaints. The difference in the number of Complaints accord-ing to with whom they were living was significant. 3. Women had signincantly more Complaints than men. Persons who were not living with their spouses had significantly more complaints than those living with their spouses.4. The higher eductional level the persons had, the less health Complaints they had. The number of Complaints accoraing to educational level was significantly different. 5. The highest number of health complaints were from persons who had involved in Commerce and industry, followed by those in Agriculture. Persons who were civil servant had the least 6. There were more complains from persons who had no hobby than those with hobbies. The complaints. The difference was significant. difference was significant. 7. Persons who said they were sexually inactive had significantly more complaints than those who said they were sexually active. As age increased, sexual activity significantly decreased. Those who lived with their spouse were significantly more sexually active. 8. The highest number of Somatic Complaints were eye fatigue, followed by nocturnal frequency, lumbago, cramps in extremities, vertigo, stiffness in Shoulder, tinnitus, common cold and constipation.

멀미는 구토 증상뿐만 아니라 현기증, 두통, 졸음, 피로감, 무기력증 등을 동반하여 선박운항자의 신체리듬과 판단능력을 저하시켜 해양사고로 이어질 수 있다. 이 연구는 승선경험이 없는 조타실 근무자(실습항해사)와 기관실 근무자(실습기관사)를 대상으로 뱃멀미 민감성에 대하여 조사하였다. 선박의 X, Y, Z축 방향에 대한 선체운동을 측정할 수 있는 선체운동계측장비(motion sensor)를 이용하여 선체의 운동을 계측하였고, 설문을 통해 조타실과 기관실 근무자의 멀미에 대한 증상 정도(VIR, VSR)를 산출하였다. 이 연구를 통해 동일한 상황에서 조타실 근무자와 기관실 근무자간에 느끼는 멀미 정도에 차이가 있다는 것을 알 수 있었으며, 멀미는 선체 움직임의 크기뿐만 아니라 움직임의 주기와도 높은 연관성이 있다는 것을 확인할 수 있었다. 또한 X축과 Y축 방향 선체운동보다 Z축 방향의 선체운동이 멀미와 상관관계가 높았다. Z축 이외 X축과 Y축에 대한 연구가 진행된다면 조타실과 기관실 근무자의 안전과 선박의 거주성 및 승선감 향상에 크게 기여할 수 있을 것으로 기대된다.

본 논문은 1990년대 이후 발표된 여화(余華)의 "재세우중호함(在細雨中呼喊)"(1993), 소동(蘇童)의 "성북지대(城北地帶)"(1994), 왕강(王剛)의 "영격역사(英格力士)"(2004)에 나타난 가족결핍과 그 서사적 대응방식을 살펴보는 것을 목적으로 삼는다. 소설에 공통적으로 등장하는 소재인 결핍된 가족은 존재의 부재를 뜻하기도 하지만 그 기능과 역할의 부재를 의미하기도 한다. 결핍을 야기하는 원인은 작품마다 서로 다르며 대응 양상 또한 차이를 보인다. 중국의 성장 서사는 오랜 시간 동안 전통의 유제와 여러 가지 정치적 압박 속에서 성장과정에서 일어나는 부모와의 갈등, 성장자 자신의 내면의 고통들을 집단의 경험 속에 매몰시켰다. 성장의 기억을 개인에게 돌려주기 시작했던 1980년대의 선취에 힘입어 1990년대 성장 서사는 지나간 연대의 강박과 피로에서 벗어난 작가들의 다양한 시도 속에서 더욱 풍부한 함의를 지니고 있다. "가랑비 속의 외침"은 친부모와 양부모에게 의도치 않은 '버려짐'을 당한 주인공의 심리적 고아의식을 보여주었고, "성북지대"는 부재된 가족에게 염증을 느끼고 또래 집단 속에서 위안을 받는 아이들의 서로 다른 성장의 이야기를 들려준다. "오, 나의 잉글리쉬 보이"는 동일시의 대상을 등장시킨다는 점에서 중국 성장소설의 주류적 서사와 구분된다. 개인의 성장은 그를 통해 진일보하고 결국 성장자 자신의 정체성을 확립하게 된다는 점에서 이 소설은 성장소설의 모범사례로 여겨진다.
