The objectives of this study were: 1) to determine smartphone addiction, visual display terminal syndrome (VDTS) related symptoms, and state anxiety among adolescents, and 2) to identify the relationship among these variables. Data were collected via selfadministrated questionnaire survey from May to June, 2013. The survey was carried out with 540 voluntary participants at 13 to 24 years old from middle schools, high schools, and universities in Korea. The presence and severity of smartphone addiction, VDTS symptoms, and state anxiety were measured using Korean Smartphone Addiction Proneness Scale, VDTS Questionnaire, and State Anxiety Inventory, respectively. Data were analyzed by Cohen’s Kappa coefficient, Kruskal-Wallis test, and Mann-Whitney U test. The mean score of smartphone addiction for all students was 2.17 ± 0.51. The mean scores of smartphone addiction depending on school grade were 2.12 ± 0.53, 2.03 ± 0.48, and 2.42 ± 0.43 for middle school, high school, and college students, respectively. Subjects who experienced minor level of VDTS symptoms had a score of 0.49 ± 0.49 for VDTS symptoms. The score was increased when the level of addiction was higher. There were significant differences in VDTS subjective symptoms among smartphone addiction groups (p<.001). High-risk group of smartphone addiction had the highest scores in every subdomain of VDTS symptoms. Differences were also found in state anxiety among the three groups with smartphone addiction. The findings of this study showed that approximately one out of three adolescents might be classified into problematic smartphone users. Therefore, it is important to educate problematic smartphone users about smartphone addiction and VDTS symptoms to prevent further addiction and aggravation of anxiety.

The aim of this study was to evaluate the musculo-skeletal symptomatic features of municipal sanitation workers and to compare differences of the musculo-skeletal symptoms by work types. We conducted descriptive cross-sectional survey concerning the musculo-skeletal symptomatic features of 315 street cleaners in Seoul and GyeongGi Province, Korea, during 2 weeks of September 2006. Questionnaires were consisted of general characteristics, occupational characteristics and musculo-skeletal symptoms. And we observed their works and evaluated their movement and posture by REBA. For work types, tools and subjective physical work loading, there were statistical difference whether or not NIOSH symptom positive on upper limb. Musculo-skeletal symptoms on upper limb were claimed from 43.2% of street cleaners, more than in 32.4% of cleaners. Musculo-skeletal symptoms on upper limb were reported higher in the group who felt their subjective physical work loading severe than in the otherwise group. The REBA results were over 'high risk stage' in street cleaners. Street cleaners had more repetitive motions than solid waste collectors on upper limbs. Works according to the criteria of musculoskeletal burdened work by the Ministry of Labor results were over 'high risk stage' of No. 2 and No. 4 in street cleaners. We found that street cleaners complained musculo-skeletal symptoms on upper limb more than solid waste collectors. This study suggests that it is necessary for street cleaners to carry out the prevention program of musculo-skeletal diseases. For street cleaner, the measure plans such as job rotation, automatic street sweepers, reducing work hours are helpful in preventing musculoskeletal symptoms on the upper limb.

Objectives The quality of life in cancer patients is important. The aim of this study is to report a case which showed symptoms improvement after treatment with modified Galgeunhaegi-tang. Methods We retrospectively reviewed the medical records. The patient's body weight and the circumference of lower extremity were measured and the subjective symptoms such as chest pain were evaluated by the NRS(Numeric Rating Scale). And the frequency of defecation was checked daily. Results The patient had received chemotherapy from March to November 2014 for 8th times. During the chemotherapy, the patient developed symptoms such as weight gain, edema of lower extremity, chest pain, headache, low back pain, and constipation. But additional evaluation and management with western medicine couldn't solve the problem. So he started to take Korean medicine. And he was transferred to our cancer center to keep continuing the treatment. After the treatment, the body weight, the lower extremity circumference and the subjective severity of chest pain, headache, low back pain were all decreased. During hospitalization at our center, the patient didn't suffer from constipation. Conclusions An elderly non-small cell lung cancer patient showed the improvement of symptoms that were continued during chemotherapy. As we can see in this case, Korean medicine can be a solution of the symptoms induced by chemotherapy, if there is no symptom improvement with western medicine.

The purpose of this study was to provide data on the development of educational programs to maintain oral health in adolescence by identifying the relevance of health behavior and symptom to adolescents. The subjects of this study were 27,919 high school students' using the 15th (2019) Youth Health Behavior Online Survey. The logistic regression analysis was used to identify the factors influencing oral symptoms. The results showed that the recognition of gingiva pain was significantly lower in the subjects with male sex, lower education level, higher income level, and higher subjective perception of oral health. Higher the stress, higher the pain recognition, revealing a statistical significance. The awareness on bad breath-related symptoms was significantly higher in the adolescents with male sex, higher degree of stress, and lower frequency of daily toothbrushing. The lower awareness on halitosis was associated with higher income and higher subjective perception of oral health, showing a statistical significance. This study found that the health behavior of adolescents had an effect on their oral symptoms and the finding is expected to help develop programs for preventing those oral symptoms.
