Background: Job training influences the overall working environment and worker's well-being. The purpose of this study is to find the relationship between job training and subjective well-being in accordance with occupations and understand the influence of task characteristics—work creativity and task variety (WCTV)—on the effect of training. Methods: A cross-sectional study based on the Fifth Korean Working Conditions Survey was conducted on 50,205 workers in the Republic of Korea. The World Health Oorganization–5 well-being index was used to measure their subjective well-being. The relationship between job training and subjective well-being was divided in accordance with the level of WCTV. Results: Training paid for by employer showed a negative effect on subjective well-being when received for more than 3 days (OR 0.88, p<0.01) in the last 12 months. Training paid for by oneself showed a positive linkage with well-being when the level of training was 1–3 days (Odds ratio = 1.55, p<0.001). This result showed different aspects in accordance with the level of WCTV. For the high WCTV group, the aforementioned results were reaffirmed, but for the group with low WCTV, job training did not show a statistically significant result on well-being. On-the-job training was not related to subjective well-being regardless of the level of WCTV. Conclusion Job training had different effects on subjective well-being depending on the type and frequency of training, as well as the WCTV. It is imperative to comprehensively apply different types of job training in accordance with the characteristics of occupations to uplift workers' well-being.

OBJECTIVE: To find factors associated with dysmenorrhea, we surveyed the obstetric and gynecologic histories as well as socioeconomic factors of Vietnamese female residents in Can Tho (southern part of Vietnam) and Bavi (northern part of Vietnam) and Vietnamese female marriage immigrants living in South Korea. METHODS: From March 2010 to March 2011, 3,017 Vietnamese women aged 17 to 42 years (mean, 25.5 years) were recruited. Socioeconomic factors as well as baseline characteristics, including gynecologic history and menstrual patterns, were collected using questionnaires. The relationships between these factors and dysmenorrhea were analyzed using chi-square test, independent t-test and logistic regression analysis. RESULTS: Dysmenorrhea was found in 58.8% of all women. The mean age and the age at menarche were younger in the women with dysmenorrhea. A longer duration of menstrual flow and severe menstrual volume increased the risk of dysmenorrhea. The prevalence of dysmenorrhea was lower in women who had experienced pregnancy, term delivery and breastfeeding. The prevalence of dysmenorrhea in Vietnamese women was also different according to their educational status. When participants were divided according to their religious preferences, atheist women showed a lower prevalence with 55%, and women who were religious had a higher prevalence of dysmenorrhea. The body mass index, menstrual cycle length, monthly income, and duration of residency in Korea were not related with the prevalence of dysmenorrhea. CONCLUSION: Socioeconomic factors as well as age, menstrual pattern and obstetric history were related with dysmenorrhea in Vietnamese women.

To find out the predictors of nocturnal arterial oxygen desaturation in patients with respiratory diseases, transcutaneous oxygen saturation(StcO2) monitoring studies using a pulse oximeter were performed during sleep in 20 patients. StcO2 was decreased more than 4% from the baseline value in 18 patients(90%) and more than 10%('Desaturator') in 8(40%). Five of the seven patients(71.4%) with awake PaO2<60mmHg and three of the thirteen patients(23.1%) with awake PaO2≥60mmHg were 'desaturators'. The awake PaO2/FIO2 and PaO2/PAO2 could distinguish 'desaturator' from 'nondesaturator, and PaO2, SaO2 or StcO2 could not. These results suggest that the nocturnal oxygen desaturation depends on the severity of the underlying disease rather than the baseline PaO2. Anthropomorphic and lung function factors could not separate between 'desaturator' and 'non-desaturator', and about a quarter of patients with a wake PaO2≥60mmHg developed significant desaturation. Therefore, it is necessary to monitor the nocturnal arterial oxygen saturation in patients with respiratory diseases regardless of their severity of airflow obstruction or awake PaO2.

As advances in the treatment of leukemia lead to further prolongation of the life span, secondary involvement of the nervous system becomes increasingly important. Especially spinal cord or cauda equina compression by leukemic cell is a medical emergency because delay in treatment often results in irreversible paralysi,s and loss of sphinctercontrol. The hospital records of 10 patients, who were admitted to the St. Mary's hospital of CUMC from January 1, 1988 to September 30, 1989 with the diagnosis of spinal leukemia were analyzed retrospectively and the results were obtained as follows; 1. The sex ratio(M: F) of the patients was 9 :1 and the age distribution rarnged from eighteen to fifty-six years with a mean age of 34.5 years. 2. The most common symptoms were pain, urinary difficulty, sensory change, and weakness etc. 3. The segment of spine involved was, approximately. 31% thoraic. 54% lumbar, and 15 % sacral. 4. Response to radiation treatment was excellent in 8 patients(80% ) especially in early treated group within 3days.

PURPOSE: The method of locally administered ketorolac and bupivacaine with epinephrine in LAG patients was examined for the control of postoperative pain. METHODS: Fifty-one patients who had undergone LAG for gastric cancer from Jan. 2005 and Aug. 2005 were enrolled in this study. All the patients were administered a fentanyl patch (25 microgram/hr) on the upper back 2 hours before the entry into the OR. Upon the completion of LAG, the patients were randomly selected for a local injection of Ketolorac and bupivacaine. Ketolorac (30 mg, 1 cc) plus 0.5% bupivacaine with 1 : 100,000 epinephrine (9 cc) was injected in the peritoneum and subcutaneous tissue of the mini-laparotomy wound in the study group, and normal saline (10 cc) was injected into the control group. The postoperative pain scores were assessed at 6 hr, day 1, day 2 and day 5 using a Verbal Numerical Rating Scale by a Wound Ostomy Continence Nurse. Meperidine (25 mg iv.) was used for additional analgesia. RESULTS: The frequency of additional analgesic requirement was significantly lower in the study group and the pain score was significantly lower at 6 hr postoperatively than in the control group. CONCLUSION: Locally administered ketorolac and bupivacaine with epinephrine is a simple and cost-effective technique for alleviating postoperative pain in LAG patients with gastric cancer.

PURPOSE: This study was undertaken to evaluate the clinical usefulness of Tensilon test, repetitive nerve stimulation test(RNST), single fiber EMG(SFEMG) test and acetylcholine receptor antibody(AchR Ab) assay for making diagnosis of myasthenia gravis(MG). METHOD: These tests were performed in 21 MG patients which were classified into 11 ocular, 5 mild generalized, 4 moderate generalized, and 1 chronic severe MG. RESULT: The overall positivity of Tensilon test, SFEMG and AchR Ab was 95%, 87%, and 76% respectively. The overall positivity of RNST was 67%; 38% on flexor carpi ulnaris, 43% on adductor digiti quinti and 62% on orbicularis oculi muscles. The positivity of each test was higher in generalized MG group than in ocular MG group. But we could observe the statistically significant difference only in the RNST(p<0.05). CONCLUSION: Tensilon test showed the highest positivity in all MG groups. So we would like to recommend the Tensilon test for the diagnosis of MG at first, followed by RNST and AchR Ab assay, and SFEMG would be indicated to MG group which showed relatively low postivity in other tests.

MIN GLASSES is specially manufactured in order to enhance satisfaction of wearer and therefore increase the effectiveness of treatment of an amblyopia and a diplopia. One of the lens is specially grounded and coated to blur vision. Cosmetically, the eye appears to wear regular glasses through the blur lens. We prospectively studied 58 amblyopic children and 10 diplopic adults. Each patient was treated with MIN GLASSES for cosmetic problems. We checked linear visual acuity of pre- and post-treatment. Questionnaires were given to the patients and parents regarding cosmetic satisfaction with treatment. In amblyopic children. 44 patients(75.9%) showed visual acuity improvement of 1.61 +/- 1.50 lines by Han's visual acuity chart. Patient compliance was 87.9%(51 patients) with patient satisfaction based on a questionnaire response. Parents were 87.9%(51 parents) positive response. In diplopic adults, 10 patients(100%) were positive response with satisfaction and demonstrated to be free of symptom of diplopia. MIN GLASSES is effective in high compliance satisfaction of amblyopia and diplopia, and improvement of visual acuity of amblyopia.

Pituitary carcinomas are rare primary adenohypophyseal tumors with cerebrospinal or extracranial metastasis. The present case, the first report of the disease in Korea, involved a 36-yr-old woman who presented with a 3-week history of headache. Brain magnetic resonance imaging revealed a 2.5-cm sellar and suprasellar mass showing heterogeneous enhancement with suspicious invasion of both cavernous sinuses. The patient underwent gross-total resection. The tumor cells were composed of polygonal cells singly or in variable-sized nests. The nuclei were large and round with prominent nucleoli. The cytoplasms was acidophilic and granular. Marked pleomorphism and frequent mitoses (3 per 10 HPFs) were found. By immunohistochemistry, tumor cells were strongly positive for prolactin, but negative for ACTH and GH. Additional immunostainings for cytokeratin, vimentin, and glial fibrillary acidic protein (GFAP) were negative. After the surgery, the patient received radiotherapy because of the atypical histologic features. The prolactin level fell from 123.17 ng/mL to 5.17 ng/mL after surgery. Nine months after the initial diagnosis, the patient died from mandibular metastasis associated with the pituitary carcinoma.
