Hemoptysis is a major reason for emergency department (ED) visits. Catamenial hemoptysis (CH), a rare condition of thoracic endometriosis, can cause recurrent hemoptysis but is difficult to diagnose in the ED due to the scarcity of cases and nonspecific clinical findings. We report a case of a 26-year-old woman who presented to the ED with recurrent hemoptysis since 2 years without a definite cause. Her vital signs and blood test findings were unremarkable. Chest computed tomography (CT) did not show any specific lesions other than a non-specific ground-glass opacity pattern in her right lung. She was on day 4 of her menstrual cycle and her hemoptysis frequently occurred during menstruation. Although there was no histological confirmation, based on her history of hemoptysis during menstruation and no other cause of the hemoptysis, the patient was tentatively diagnosed with CH and was administered gonadotropin-releasing hormone. She had no recurrence of hemoptysis for 3 months. While CH is difficult to diagnose in the ED, the patient's recurrent hemoptysis related to menstruation was a clue to the presence of CH. Therefore, physicians should determine the relationship between hemoptysis and menstruation for women of childbearing age presenting with repeated hemoptysis without a definite cause.

The objective of this study was to find a linkage of ideological background between agricultural extension education and lifelong education. This study was conducted by analyzing the studies related to agricultural extension and lifelong education. Review of literature and documents was main methods of this study. The study reviewed and analyzed the concepts, characteristics and ideology of lifelong education, and presented some general characteristics of lifelong education in the context of educational ideology. As a result of the study, the following five characteristics of lifelong education in the context of educational ideology were presented; 1) lifelong education is the supreme concept of education and includes all kinds of education, 2) lifelong education is the future direction of educational ideology and philosophy rather than a kind of educational practice, 3) lifelong education means the security for a right of learning through the entire life-span of an individual, 4) lifelong education has the innovative function of the existing situation of education; viewpoint, contents, and methodology of learning, 5) Lifelong education runs ultimately towards a 'learning society'. Agricultural extension and lifelong education shared the similar ideological background in general, and have the similar basic philosophy. The ideology and philosophy of lifelong education should be reflected into the ideology of agricultural extension to broaden the perspectives of agricultural extension in the future.

Background: The role of totally implantable central venous port (TICVP) system is increasing. Implantation performed by radiologist with ultrasound-guided access of vein and fluoroscope-guided positioning of catheter is widely accepted nowadays. In this article, we summarized our experience of TICVP system by surgeon and present the success and complication rate of this surgical method. Materials and Methods: Between March 2009 and December 2010, 245 ports were implanted in 242 patients by surgeon. These procedures were performed with one small skin incision and subcutaneous puncture of subclavian vein. Patient's profiles, indications of port system, early and delayed complications, and implanted period were evaluated. Results: There were 82 men and 160 women with mean age of 55.74. Port system was implanted on right chest in 203, and left chest in 42 patients. There was no intraoperative complication. Early complications occurred in 11 patients (4.49%) including malposition of catheter tip in 6, malfunction of catheter in 3, and port site infection in 2. Late complication occurred in 12 patients (4.90%). Conclusion: Surgical insertion of TICVP system with percutaneous subclavian venous access is safe procedures with lower complications. Careful insertion of system and skilled management would decrease complication incidence.

Purpose : The purpose of this study was to investigate the effects of core exercise on the static balance for females in their twenties. Methods : The core exercise program was conducted 3 times per week for 4 weeks. The result is based on the analysis of measuring static balance before and after the core exercise program. By using the GOOD BALANCE system, the assessment of the static balance ability was made before and after the exercise of 6 postures: normal standing, one left leg?and one right leg standing with eyes open and closed respectively. For each case, the experimental data were obtained in 3 items: mean X speed, mean Y speed, and velocity moment. Statistical analysis was performed using SPSS/Win(10.0) version and Willcoxon signed rank test. Results : From the result of this study, we found that mean X speed, mean Y speed and velocity moment of total postures significantly increased after the 4 week program of core exercises. Conclusion : These finding indicate that core exercises could be beneficial to females in their twenties due to the effect of increasing static balance.

The objective of the current study was to assess the comparative risk associated with exposure to particulate matter (PM) while commuting via different public transport modes in Fukuoka, Japan. For the given routes and measuring days, a trip-maker carried a lightweight portable bag loaded the real-time measurement devices which take simultaneous measurement for size-fractioned particle number concentration, $PM_{2.5}$ mass concentration, and total suspended particle (TSP) collection. The results of the present study have shown significant differences between public transports as commuting modes in Fukuoka. The PM exposure levels on subway platform and inside subway train were overwhelmingly higher than those of other points on commuting route. The relative ratio between modes (i.e., the ratio of $PM_{2.5}$ inside subway to that inside bus) provides an idea for choosing a right commuting mode for our health. This study clearly provided evidence of the extremely high levels of iron exposure by subway uses compared to bus uses. The result of theoretically reconstructed mass concentration of $PM_{2.0-0.3}$ collected on subway platform suggests that the PM of underground subway will be associated with PM both generated in subway system and inleakaged from outdoor environment.

The purpose of this study was to examine the use of skincare & obesity clinics, customer satisfaction with franchise and non-franchise skincare & obesity clinics and customer selection criteria in the region of Busan in a bid to suggest some of the right directions for marketing strategies for the inauguration of skincare & obesity clinics. The subjects in this study were 240 users of 16 different skincare & obesity clinics selected from Busan. Out of the clinics, four franchise clinics and four non-franchise clinics were selected from the major commercial districts, and four franchise clinics and four non-franchise clinics were selected from the residential areas. Concerning the influence of three leading factors on customer satisfaction, all the service price, material service and human service had a significant impact on customer satisfaction in the franchise model for the commercial districts. In the case of the franchise clinics in the residential areas, only service price exerted a significant influence on customer satisfaction. In terms of the non-franchise model for the commercial districts, customer satisfaction was under the significant influence of human service and material service, and that was significantly affected by human service and service price in the non-franchise model for the residential areas.

In many companies field failure data is used to predict the future number of failures, especially when an unexpected failure mode happens to be a problem. It is because they want to predict the number of spare parts needed and the future quality warranty cost associated with the part based on the predictions of the future number of failures. In this paper field summary data is used to predict the future number of failures based on an appropriate distribution. Other types of data are also investigated to identify the appropriate distribution.

Purpose: The purpose of this study was to investigate the relationship among use of earphones, stress level, and hearing threshold in university students. Methods: Study subjects included 210 university students (76 men, 134 women). Data were collected by questionnaire and audiometer from December 17 to 20, 2011. The SPSS win 19.0 program was used for data analysis by descriptive statistics, t-test, one-way ANOVA, and Pearson's correlation coefficient. Results: 1) 4KHz, 6KHz hearing threshold of subjects who used earphones was higher than average hearing threshold of same age group. 2) Not significant differences in hearing threshold were observed according to frequency of use, and stress level. 3) Significant differences in 4KHz hearing threshold were observed according to earphone volume. 4) A significant positive correlation was observed between frequency of use and stress level (r=0.15, p<.05), earphone volume, and 4KHz hearing threshold (left) (r=0.15, p<.05); however, a negative correlation was observed between stress level and 4KHz hearing threshold (right) (r=-0.14, p<.05). Conclusion: A significant positive correlation was observed between frequency of use and stress level and earphone volume and 4KHz hearing threshold (left). Development of a program for hearing conservation is needed.

The synthetic oligomers called nos right palindrome (RP) element and left palindrome (LP) element were inserted into nos.minimal promoter nos 5'-101 deletion mutant The activity of nos promoter was measured by studying the expression pattern of gene fusion between nos promoter and reporter genes such as chloramphenicol acetyltransferase and $\beta$-glucuconidase. Analysis of transgenic tobacco plane carrying transgene showed that the activity of nos minimal promoter activity was recovered by insertion of synthetic nos RP element. Nos RP element insertion of nos minimal promoter was induced by auxin, dithiothreitol, salicylic acid and methyl jasmonate.
