In Korea, unemployment is mainly due to the economic recession since the foreign exchange crisis in 1997, the structural problems of labor market, and the education system which can not cope with the changes of socioeconomic environments. The following countermeasures are required to solve the problems of unemployment. First, the government should establish the employment stabilization infrastructure and network system which help to improve labor market function by serving workers with information, training and consultation for jobs. Second, considering the practice of stressing job experience, the youth should be given the opportunity of on-the-job training in order to choose their jobs and decide their courses in life. Third, the education-industry-labor authorities should develope job education & training programs and workers should be educated and trained to he suitable for various types of jobs.

Purpose: As the first-line pharmacotherapy for erectile dysfunction (ED), phosphodiesterase type 5 (PDE5) inhibitors are widely used and their clinical efficacy is well established. But up to now, most of these comparative studies have been based on questionnaires, and Udenafil and Mirodenafil, which have recently been developed in South Korea, have not yet to be compared in clinical studies. We compared and analyzed the efficacy of five PDE5 inhibitors using the sexual stimulated (SS)-Penogram. Materials and Methods: A total of 347 patients taking PDE5 inhibitors for the treatment of ED and underwent SS-Penogram was enrolled in this study. AUC (area under the curve) of SS-Penogram was compared in each PDE5 inhibitors. Differences in AUC according to age, combined disorders, serum testostereone and prolactin, cholesterol and IIEF were also analysed using Chi-square and Kruskal-Wallis test. P-value less than 0.05 was considered as statistically insignificant. Results: Ratios of Type I curves in medication groups with normal erection were not statistically different before and after medication. Ratios of the excellent response (>50 % increase in area under the curve) and non-response groups (no increase or even decrease in area under the curve) in each medication group were not statistically different. Conclusions: In this clinical comparative study of the efficacy of PDE5 inhibitors using the SS-Penogram, there were no definite differences in efficacy among PDE5 inhibitors.

A 48-year-old man, with a history of advanced gastric cancer, underwent computed tomography(CT) for a postoperative 5 year follow-up. The CT scan showed a small bladder tumor. Pelvic magnetic resonance imaging and cystoscopy were performed consecutively, which revealed a small, ovoid and well-demarcated submucosal tumor at the anterior bladder, but without mucosal abnormality. The patient underwent a mass enucleation, which was 2x1.5x1cm in size, and light-pinkish, multi-lobulated and encapsulated. On the cut section, it was revealed to be a unilocular cyst, filled with brownish mucoid material. A histological examination showed focal stratified mucinous epithelium, without cellular atypia, which was admixed with mucinous pool formation. There was no evidence of a metastatic tumor or a tumor of urachal origin. Thus, it was diagnosed as a primary mucinous cystic neoplasm in the submucosa of the bladder, as initially thought, which has never been reported in the literature

Purpose: We assessed the impact of using a porcine model on the training of laparoscopic partial nephrectomy(LPN) and compared the training effectiveness between surgeons with and without previous laparoscopic experience. Materials and Methods: Surgeon A had previous laparoscopic experience, with the exception of LPN, while surgeon B had no prior laparoscopic experience. A tumor model was created by subcapsular injection of liquid plastic(Smooth-Cast 320) in the kidney. We recorded the total operation time, the bowel dissection time, the renal pedicle dissection time, the warm ischemic time, the mass resection time, the suture time, and the presence of major complications for each surgeon. Results: The mean operation time was significantly shorter for surgeon A compared to surgeon B(49.1±4.5 and 63.6±8.4 minutes, respectively, p< 0.001). Although the mass resection time was significantly shorter for surgeon A as well, there were no significant differences between the two surgeons in terms of warm ischemia time and suture time. As the training progressed, surgeon B improved in all surgical steps and surgeon A showed improvement in time for warm ischemia and suturing the defect. Five complications occurred(two cases by surgeon A and three cases by surgeon B). Conclusions: A porcine model improved the skills needed for LPN, including shortening the warm ischemia and suture times. LPN is a procedure requiring technically-demanding skills that can be improved by training using a animal model, regardless of the previous laparoscopic experiences.
