Purpose: We investigated the clinicopathological features and management for superficial nonampullary duodenal tumors (SNADTs). The safety and feasibility of laparoscopic management, especially laparoscopic endoscopic cooperative surgery (LECS), were evaluated. Methods: A total of 59 patients with SNADTs who underwent operations from January 2009 to December 2018 at all 8 institutions of the Catholic Medical Center were identified in our comprehensive multi-institutional database. Clinicopathological and surgical data on the 4 anatomical regions of the duodenum were collected and compared. Characteristics of conventional laparoscopic procedure (laparoscopy-only) and LECS procedures were also compared. Results: There were significantly more asymptomatic patients with tumors in the first and second vs. third and fourth duodenal regions. Gastrointestinal stromal tumors (GISTs), carcinoids, and ectopic pancreatic tumors were identified in 32, 12, and 5 cases, respectively. Forty-two patients (71.2%) underwent laparoscopy. Of patients undergoing laparoscopy, the LECS group exhibited significantly more endophytic features and smaller tumor sizes (P < 0.001 and P < 0.001, respectively). Although no significant difference in the wedge resection or postoperative complication rate was seen between the 2 groups (P = 0.096 and P = 0.227, respectively), the wedge resection rate was higher, and the complication rate lower, in the LECS group than the conventional laparoscopic surgery group. Conclusion: Most of the SNADTs located in proximal duodenum were detected incidentally. GISTs were the most common diagnoses of SNADTs in all locations. In treating these tumors, laparoscopic resection is safe and feasible. Especially, LECS may be ideal for treating small endophytic tumors, minimizing over-resection and postoperative complications.

Purpose: The surgical outcomes of end-stage renal disease (ESRD) patients undergoing radical gastrectomy for gastric cancer were inferior compared with those of non-ESRD patients. This study aimed to evaluate the short- and long-term surgical outcomes of ESRD patients undergoing laparoscopic gastrectomy (LG) and open gastrectomy (OG) for gastric cancer. Materials and Methods: Between 2004 and 2014, 38 patients (OG: 21 patients, LG: 17 patients) with ESRD underwent gastrectomy for gastric cancer. Comparisons were made based on the clinicopathological characteristics, surgical outcomes, and long-term survival rates. Results: No significant differences were noted in the clinicopathological characteristics of either group. LG patients had lower estimated blood loss volumes than OG patients (LG vs. OG: 94 vs. 275 mL, P=0.005). The operation time and postoperative hospital stay were similar in both the groups. The postoperative morbidity for LG and OG patients was 41.1% and 33.3%, respectively (P=0.873). No significant difference was observed in the long-term overall survival rates between the 2 groups (5-year overall survival, LG vs. OG: 82.4% vs. 64.7%, P=0.947). Conclusions: In ESRD patients, LG yielded non-inferior short- and long-term surgical outcomes compared to OG. Laparoscopic procedures might be safely adopted for ESRD patients who can benefit from the advantages of minimally invasive surgery.

대학졸업생의 취업동향과 그 변동추세 및 이에 작용하는 여러가지 교육적, 사회적 요인을 규명함으로써 대학생 및 대학 졸업생의 직업지도의 방향을 설정하고 그 가능한 실현방안을 모색하기 위하여, 경북대학교의 농대·문리대·법대·사대·의대 및 영남대학교의 공대, 상경대·약대의 1961∼1965년도 졸업생 6,421명을 대상으로 그들의 취업현황, 선직 변동추세 및 이에 관련된 23개요인을 질문지를 통해 조사한후, 조사대상을 불변자와 전직자로 나누어 각기 그들의 전반적인 취업동향과 변동추세를 비교분석하였다. 그 결과 (1) 대학졸업생의 취업현황은 전체적으로 교사가 가장 많고 그 다음이 공무원·의사·사업등의 순으로 나타났으며 대학별로는 특히 의대·사대·약대 졸업생이 전공학과의 특수성을 반영하는 직업적 동질성의 정도가 높은데 비하여, 농대·법대·문리대졸업생은 이러한 경향이 없이 비교적 다양한 직업군을 형성하고 있다. (2) 대학졸업생의 선직변동추세는 (a) 졸업생의 73.26%가 처음 선택한 직업에 그대로 머물러 있으며 나머지 약 26.74%가 한번 혹은 그 이상 전직한 것으로 나타났으며, (b) 한편 전직자의 전직내용은 동일형태나 동일수준내의 전직이 가장 많고, (c) 이러한 전직 변화현상은 처음 선택한 직업과 인접직업군에로 선직변동이 일어나는 일정한 경향성을 보여주고 있다. (3) 선직변동의 규정요인으로서는 취업결정시기, 취업절차, 적합도(능력·흥미·적성·가치관), 전직희망도, 이상직업과 직업의 일치도에 있어 진직자와 불변자간에 의의있는 차이가 있으며, 이것이 선직변동의 한 요인으로서 작용하고 있다. 그리고 (4) 이러한 결과를 통해서 얻어진 직업지도상의 시사점도 또한 논의되었다. Being emphasized practically the necessities of vocational guidance activities and programs for college students and graduates, unfortunately there has been little inquiry into the vocational behavior in exploratory and trial work periods that occur during the first few years after college. To investigate the vocational behavior of male college graduates during their early work experiences, this study was undertaken to identify the career patterns of male college graduates. The job histories of 6,421 male alumni graduated from Kyungpook National University and Young Nam University in 1961 to 1965 were examined. Of them the post-college vocational behavior of 4,014 alumni were identified and descriptively analyzed. And a questionnaire was mailed to this gross study population and thus the actual population surveyed amounted to 905 male college graduates. Based on his job history each respondent was classified into a stable career pattern and a changed career pattern, and vocational behavior of these two career patterns was investigated and compared. The main findings of this study were revealed as follows; 1. 73.26 percent of male college graduates remain in their initial occupational fields and 26.74 per cent of male college graduates have one or more exploratory jobs. And in a case of the changed career pattern the occupational change goes to related job in the aspects of occupational type and level of initial job. 2. 36.44 percent of male college graduates engages in the occupational field of teaching and the other in business, organization, technology etc., in order. And occupational homogeneity of alumni graduated from college of education, medicine and pharmacology is rather higher than that of alumni graduated from college of law, arts & science, agriculture, technology, and commerce. 3. Of 23 variables investigated, only 9 variables were found to have significantly different influences between a stable career pattern and a changed career pattern. These variables are time to decision to obtain initial job, method used to obtain job, one's assumed suitability of his job to his ability, aptitude, interest and value system, desire to change job, and congruence between ideal job and present job. And implications for vocational guidance activities and programs of these findings are also suggested.

The effects of mercury on the photosynthetic machinery of Ulva pertusa Kjellman were examined by measuring oxygen evolution, pigment contents, and fluorescence induction process. By increasing the concentration of added HgCl₂upto 0.6 ppm, oxygen evolution rate and pigment contents were decreased gradually. Chlorophyll α/b ratio was also decreased, suggesting that chlorophyll α was decreased (probable degraded) more rapidly than chlorophyll b by the treatment of mercury. Overall pattern of the fluorescence induction curve was very similar to that measured from terrestrial plant leaves. However, several characteristic differences observed: (1) fluorescence intensity decreased very rapidly after P(peak), (2) D(dip)-P increase was significantly reduced when measured 30 sec after a saturation pulse, and (3) Fmax was decreased when measured again 30 sec after a first measurement by using a saturation pulse. Due to the second and third characteristics, at least 30 min dark interval was required before starting an additional measurement using a sample. When the mercury concentration was increased, Fp (fluorescence intensity at P) was decreased gradually, but Fi(the intensity at inflection) did not increased. The decrease in Fp could be explained by the inhibition of mercury at a site near oxygen evolving complex. By the addition of 0.2 ppm HgCl₂, Fp was increased slightly without significant changes in ID pattern. This result suggests that the inhibition site of mercury at the electron transport chain on the reducing side of PSⅡ is not the Q_B or DCMU binding site. When the mercury concentration was increased, Fo was decreased slightly, but Fmax, (Fv)m/Fmax, qQ and qN was decreased significantly. By the addition of mercury more than 0.6 ppm, photosynthetic activities was almost completely blocked but pigment contents was stayed the same.
