Purpose: The purpose of this study was to analyze the quality of reports on observational studies published in the Korean Journal of Women Health Nursing (KJWHN). Methods: Forty-six studies using cross-sectional designs published in KJWHN from January 2011 to June 2013 were selected for analysis. Selected articles were reviewed and evaluated by three reviewers using the 22 items of the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement. As some of 22 items had more than one check point, further broken down, 34 checklist items were used for analysis. Results: Overall, the reviewed studies provided sufficient descriptions for many STROBE items. Seven of the 34 items were found to be not applicable, and 15 of the remaining 27 items (55.5%) were evaluated as 'sufficient' in reporting. Only one study included a flow diagram illustrating participation and this lack of flow diagram was the weakest area of reporting in this review. Conclusion: Clearer reporting of cross-sectional studies can be attained by attention to vulnerable areas of reporting, such as including a flow diagram of participants, descriptions of sources of bias and reason for non-participation, and describing limitations of the study. Issues regarding the application of STROBE statement items should be actively discussed in order to aid future revision and clarification of items included in STROBE statement.
A comparison was made between workers exposed to organic solvents and those not exposed to them regarding stress perception and psychopathology, using GARS scale and SCL-90-R. The exposed group scored significantly higher than the non-exposed group in stress perception relevant to job-wort changes in relationship, sickness or injury, financial, and overall global area. The exposed group was significantly higher in somatization scale than the non-exposed group. However, there was no significant correlation between duration of exposure and psychopathology. In each of the groups. female workers showed more psychopathology than male ones. Age showed significantly nagative correlation with psychopathology. These results suggest that the exposed group shows higher stress perception and more psychopathology than the non-exposed group. Thus. it is emphasized that health policy makers as well as employers should pay more attention to health. espcially mental health for the workers exposed to organic solvents.

Objective : The cervicothoracic junction (CTJ) is a biomechanically and anatomically complex region that has traditionally posed problems for surgical access. In this retrospective study, we describe our clinical experiences of the treatment of metastatic spinal tumors at the CTJ and the results. Methods : From June 2006 to December 2011, 23 patients who underwent surgery for spinal tumors involving the CTJ were enrolled in our study. All of the patients were operated on through the posterior approach, and extent of resection was classified as radical, debulking, and simple neural decompression. Adjuvant radiation therapy (RT) was also considered. Visual analog scale score for pain assessment and Medical Research Council (MRC) grade for motor weakness were used, while pre- and post-operative performance status was evaluated using the Eastern Cooperative Oncology Group (ECOG). Results : Almost all of the patients were operated using palliative surgical methods (91.3%, 21/23). Ten complications following surgery occurred and revision was performed in four patients. Of the 23 patients of this study, 22 showed significant pain relief according to their visual analogue scale scores. Concerning the aspect of neurological and functional recovery, mean MRC grade and ECOG score was significantly improved after surgery (p<0.05). In terms of survival, radiation therapy had a significant role. Median overall survival was 124 days after surgery, and the adjuvant-RT group (median 214 days) had longer survival times than prior-RT (63 days) group. Conclusion : Although surgical procedure in CTJ may be difficult, we expect good clinical results by adopting a palliative posterior surgical method with appropriate preoperative preparation and postoperative treatment.

This paper aims at exploring how a high school student is engaged with C computer programming language and explore deep aspects of programming experiences based on video recalled interview as part of portraiture. The single case was selected and several in-depth interviews and video recording were arranged after Oct 2011. The portrait of K reveals interesting strands of his computer programming experiences with his own thinking patterns and exploring ideas for more concrete ways of coding his thinking similar to scientific experiments; ie, design-development-implementation-debugging-revision. Overall, this case illustrates how the inner aspects of subjective programming experiences on the tower of Hanoi were integrated and unified within himself for inner growth. We discussed the student's inner faculties as part of the student's unity and suggested future research direction.
This study aimed to evaluate the necessity of updating current nutritional standards for school lunch programs in Korea. The study was performed both theoretically and practically considering the present physiques and nutrient intakes of school students. Theoretically, adequacy of types of nutrients and nutrient reference values were analyzed. Specifically, the adequacy of the types of nutrients were reviewed by applying the same selection procedures used in the 2007 revision of current standards in order to evaluate the necessity of updates. The nutrient reference values were compared with those in the U.S., Japan, and Taiwan in terms of setting year, basic data, and setting method. Practically, a focus group interview with six school nutrition teachers was conducted to investigate any operational difficulties in applying the current standards to school foodservices in Bucheon on October 1, 2015. As a result, nine types of nutrients were decided, which excluded protein and thiamin from the current ones. The nutrient reference values needed updating toward more adequate levels by reflecting more various and recent basic data considering daily nutrient intakes and the actual percentages of intakes from lunches of school students. The results showed that school nutrition teachers found it difficult to apply the current standards to school foodservices, especially as school level increased from elementary through middle to high schools mainly due to protein and calcium. Overall, the study results imply that the current nutritional standards for school lunch programs in Korea need updating to reflect the current physiques and actual nutrient intakes of school students.

Background: $Abb{\acute{e}}$ flap technique is one of the most challenging operations to correct horizontal deficiencies in secondary cleft lip deformity. Since its first introduction, the operative method was dynamically modified from simple variation to complete conceptual change, but conventional $Abb{\acute{e}}$ flap has many drawbacks in esthetic and functional aspect. Our purpose was reconstructing the symmetry of Cupid's bow and central vermilion tubercle with minimal sequalae. Methods: From 2008 to 2016, this technique was applied to 16 secondary cleft lip patients who had total or more than 60% of unilateral deficiency of Cupid's bow and central lip or tubercle pouting deficiency. A quadrangular-shaped flap was transferred from vermilion including skin and white line of central or contralateral lower lip. Pedicle division and insetting were made at 9 (unilateral) or 10 (bilateral) days after transfer. Secondary lip revision was done with open rhinoplasty after wound maturation. Results: Overall satisfaction was high with modified technique. Scar was minimally noticeable on both upper and lower lip especially. Balanced Cupid's bow and symmetric vermilion tubercle were made with relatively small size of flap compared to conventional $Abb{\acute{e}}$ flap. An accompanying benefit was reduced ectropion of lower lip, which made balanced upper and lower lip protrusion with more favorable profile. Conclusion: A new modified $Abb{\acute{e}}$ flap technique showed great satisfaction. It is worth considering in secondary cleft lip patient who has central lip shortage and asymmetry of upper lip vermilion border line. Our technique is one of the substitutes for correction of horizontal and central lip deficiency with asymmetric Cupid's bow.
The effect of permanganate concentration and refluxing time on the test COD results were investigated, as a validation test of the revised procedure. The amended protocol involves the use of a more dilute(1/2.5) permanganate solution(0.010N) and a shorter(1/3) refluxing period(20 min). This revision resulted only 70% of the COD value determined by the old procedure with 8 somewhat improved precision(CV 4.6%${\rightarrow}$3.3%). The dominant factor that influences the decrease in the COD result is the oxidant concentration, being two thirds of the overall effect. The same results were obtained in the comparison test using seawater samples.
Purpose: The rectus abdominis musculocutaneous (RAM) flap has contributed to the efficient reconstruction of soft tissue defects. The flap has the advantage of easy dissection, minimal donor site morbidity, and the constant vascular anatomy with long pedicle. Authors used the free RAM flap to reconstruct multi-located soft tissue defects while still considering functionality and aesthetics. We present the long-term outcomes and versatility of free RAM flaps. Materials and Methods: From 1994 to 2004, all patients who underwent soft tissue reconstruction with free RAM flap were reviewed retrospectively. The site of the reconstruction, vessels of anastomosis, type of RAM flap, and outcomes, including flap success rate, hospital stay after flap transfer, conduction of secondary procedure, flap complications, and donor-site complications were analyzed. Results: Twenty-one patients underwent 24 free RAM flaps in site of breast, face, upper extremity and lower extremity. Mean follow-up period was 36.1 months (range, 3~156 months). The overall success rate was 92% with only a loss of 2 flaps. Minor complications related to transferred flaps were necrosis of 2 partial flaps, hematoma formation in 3 cases, and a wound infection in 1 case. Donor site morbidity was not observed. Debulking surgery was performed in 4 patients, and scar revision was performed in 3 patients. Conclusion: Free RAM flap is a workhorse flap for general soft-tissue reconstruction with minimal donor site morbidity with aesthetically good results. Thus, the free RAM flaps are versatile, and sturdy for any sites of soft-tissue where reconstruction could be performed.

This study aims to prepare basic resources for the development of child-care by figuring out the main characteristics of child-care history, laws, and current status in Korea. First of all, in the section of child-care history, the overall trend of child-care affaires were examined by classifying it into stage 1-Child Welfare Act, stage 2-Early Childhood Education Promotion Act, stage 3-Initial Period of Child-Care Act and stage 4-Complete Revision of Child-Care Act. Second, as for child-care related laws, basic laws such as Infant and Child-Care Act, and related laws such as Early Childhood Education Act and Child Welfare Act and other related laws such as Equal Employment Opportunity and Work Family Balance Assistance Act, act on Support for Disabled Children's Welfare and Social Welfare Services Act, the information related to child-care was specified. Third, as for current status of child-care, general status, status of child-care centers and children, and types of child-care centers were examined respectively.
Purpose: The purpose of this study was to develop a self-directed e-learning program for ICU nurses and to evaluate how the proposed e-learning program affects the level of knowledge, nursing performance and job satisfaction of ICU nurses. Methods: The e-learning program was developed with the Computer Assisted Instruction Design Model using sources of self-efficacy which included the inactive attainment, vicarious experience, and verbal persuasion of ICU nurses. The program was evaluated by experts. Following the revision of the program, it was applied to a total of 59 ICU nurses (experimental group n=29, control group n=30) from three hospitals. Four weeks later, we measured the level of knowledge, nursing performance and job satisfaction. Results: The level of knowledge significantly improved in the experimental group (t=5.691, p<.001). Moreover, the level of nursing performance significantly increased in the areas of circulatory diagnostic test (t=2.143, p=.039), EKG (t=2.911, p=.006), aortic balloon pump (t=2.491, p=.017), and nebulizer therapy (t=2.085, p=.044). Overall, job satisfaction did not significantly increase (t=1.664, p=.105); however, job satisfaction in terms of relationships with coworkers (t=2.371, p=.023) and the needs of nursing performance (t=2.940, p=.006) were significantly increased. Conclusion: The results showed that the proposed e-learning program using sources of self-efficacy from ICU nurses was an effective learning method to increase the level of knowledge and nursing performance. The propose de-learning program would be a useful teaching tool for ICU nurses improving the quality of ICU patient care.
