  • Universities have recently introduced problem-based learning (PBL) to various subjects to enhance problem-solving skills (including self-directed learning and small-group learning) required in industry. The PBL module was applied to the personal production process in a draping class. A study was based on a questionnaire after conducting two PBL modules with a group of students. Each PBL module included 'design analysis', 'presentation of flat sketch and draping plan', 'discussion of the plan', 'evaluation of the draping result and correcting the problem', and 'final evaluation of the completed project'. Results showed that satisfaction with the PBL method and its activities was higher than satisfaction with existing teaching methods. In particular, among the various components, the 'design analysis' and 'the presentation step of flat sketch and draping plan' stages were more helpful to students compared to small-group discussion. Moreover, the effects of PBL were observed through student reflection essays, in which students suggested that PBL was very effective in enhancing problem-solving through self-directed and small-group learning. Despite the overall satisfaction with PBL, students expressed some minor difficulties associated with awkwardness with a novel learning method, lack of diverse perspectives among each group, and poor communication skills. Therefore, the study shows that PBL is highly likely to be useful to students when they are solving pattern drafting problems and making samples through self-directed learning and small-group learning.

  • Background Human bite wounds in emergency department need evaluation in regard of reconstruction. These are due to occlusive bite injuries over face. Most commonly, human bites over face involve ear and nose, and may lead to avulsion injury. Defects over nose can be reconstructed immediately after debridement or delayed till the wound heals and scar becomes supple. Thorough wash and lavage with broadspectrum antibiotic cover has utmost importance in preventing cartilage infection. Methods We report 20 cases of human bite injuries over nose who presented to us in emergency department between 2018 and 2020. At the time of presentation the wound was assessed for closure. If not possible, patient was planned for delayed reconstruction after 3 months. In case delayed reconstruction was planned, the skin and nasal mucosa were approximated at first presentation. The patients underwent paramedian forehead flap after recreation of defect with conchal cartilage graft. Second stage of flap detachment and insetting was done after 3 weeks. After three weeks of second stage, third stage of flap thinning was done. Patients were followed for 3-6 months and subjective satisfaction was noted. Results Nineteen patients underwent delayed staged reconstruction with paramedian forehead flap and one underwent primary wound closure. The flap survival was 100%. The patient satisfaction was excellent in most cases. Conclusion We recommend delayed reconstruction for human bite nasal injuries. For reconstruction, paramedian forehead flap with conchal cartilage graft, if required, provides excellent reconstructive option with good contour and color match and minimal donor site scar.

  • This study investigated the effective pedagogical strategies for sewing by examining the efficacy of sewing videos as supplemental learning materials and demonstration tools. Sewing videos were created for face-to-face apparel construction courses, and students' opinions on sewing videos as an educational tool were collected. Videos with subtitles were offered to Apparel Construction Course 1, whereas videos with narration and subtitles were offered to Apparel Construction Course 2. As "supplemental learning materials," students rated videos as more effective for learning and satisfying than "documents with text and images." The effectiveness and satisfaction scores for Apparel Construction Course 2 were significantly higher than those for Apparel Construction Course 1. Furthermore, videos were utilized significantly more than documents, and most students preferred videos over documents. The main benefits of videos as supplemental learning materials were repetitive learning at the learner's convenience and the detailed presentation of the sewing process. Students regarded narration as more effective and satisfying than subtitles. Narrations were expected to be offered along with subtitles. As "demonstration tools," students rated videos as more effective for learning and satisfying than traditional "sewing samples." Students preferred "demonstration with videos" to "demonstration with sewing samples." The main benefits of video demonstration were a close-up view, presentation of the entire sewing process, and shorter wait time without the need for group teaching. Students wanted more sewing videos and narrations to be offered, and various sewing machine feet to be used in the videos. Educational methods for sewing were suggested based on student opinions.

  • This study is to examine grammar understanding with beginner English speakers according to presentational methods of grammatical content. 18 English-speaking Korean beginners were randomly assigned and divided into two groups. We first examined if there was a statistically significant difference between the two groups in grammar comprehension with and without illustrations. It was found that the group given the presentation illustrations showed greater understanding than the group without them. Second, no statistically significant difference in grammar understanding was found between the groups with and without materials marked for their awareness. Third, no statistically significant difference was found between the groups with the order of presenting content elements related to grammatical items. This study is to affirm the importance of illustrations as a component of Korean textbooks.

  • 설계VE 활동작업 중 대상의 기능을 철저하게 분석할 수 있는 기능분석 활동은 그 중요성에도 불구하고 수행자의 인식부족, 분석방법에 대한 어려움 및 설계VE 활동 시간적 제약 등의 이유로 활동 자체가 약화, 변형되거나, 생략되는 경우가 발생하고 있다. 이와 같이 기능분석이 변형된 VE활동은 아이디어 창출과정에 있어서 기능부분이 약화된채 아이디어의 결과를 창출함으로 신뢰성이 매우 떨어진다고 할 수 있다. 따라서 본 연구는 현재 시행되어진 설계VE작업중 기능분석활동 부분을 분석하여 이를 활동유형별로 분류, 그 특징을 파악한다. 이를 통해 기능분석 활동에 대한 올바른 이해를 확립하고, 기능분석 활동의 개선부분을 도출하여 올바른 설계VE 활동을 유도하고자 한다.

  • 목적: 윌슨병으로 진단 받은 환자들의 진단 당시의 임상 양상의 분포, 발병 연령과 검사 소견들을 파악하고, 또한 초기 발견의 중요성을 고찰하고자 본 연구를 시행하였다. 방법: 1990년 1월부터 10년간 부산 백병원에 입원하여 윌슨병으로 진단 받은 환자 20례를 대상으로 진단 당시의 증상과 증상 발현시기, 진단까지의 기간, 검사 소견 등을 후향적으로 조사하였다. 결과: 20명의 환자들 중에 간 증상 단독 발현은 12명(60%), 그 중 2명은 우연히 AST/ALT가 증가된 것을 발견한 경우였으며, 신경 증상 단독 발현은 2명(10%), 신경 정신증상과 간 증상이 같이 나타난 경우는 4명(20%), 혈액 증상이 주된 경우 1명(5%), 그리고 증상이 없으며 AST/ALT도 정상이나 가족 검진에서 혈중 ceruloplasmin이 감소된 것을 발견한 경우가 1명(5%) 있었다. 모든 환자들에게서 혈중 ceruloplasmin의 농도는 유의하게 낮았다. 가족력은 5례에서 있었다. 간 증상은 진단시 이미 간경화로 진행한 것을 초음파로 진단한 경우가 12명(60%)이었으며, 이 중 2명이 진단 후 1년 내에 사망하였다. 결론: 윌슨병은 빠른 진단과 치료가 중요하다. 그러나 다른 유전성 대사질환들과는 달리 전체 신생아의 선별검사는 의미가 없으며, 환자가 있는 가족에서 혈중 ceruloplasmin과 소변 내 구리, 간 효소 수치와 각막을 검사하는 것이 좋다. 소아기에 간염의 증상이나 지속적으로 증가된 간 효소 수치를 보일 때 또는 가족 중에 원인이 밝혀지지 않은 간질환의 가족력이 있을 때에는 윌슨병을 의심해 보아야 하겠다. 또한 청소년기 이후에 추체외로 증상이나 소뇌 증상 등 운동 신경계의 증상을 호소하든지 혈액 이상, 소변 검사상 이상이 복합적으로 나타나는 경우 등에서도 혈중 ceruloplasmin을 꼭 확인해 보아야 한다. 그 외에 신경 증상 및 정신 증상을 주소로 내원한 경우에도 간기능 검사를 꼭 시행해 보아야 하겠다.

  • Background: Breast cancer is known to be one of the most prevalent cancers among women in both developing and developed countries. The incidence of breast cancer in Pakistan has increased dramatically within the last few years and is the second country after Israel in Asia to have highest proportional cases of breast cancer. However, there are limited data for breast cancer available in the literature from Pakistan. Objectives: The study was conducted to bring to light the common clinical presentation of breast cancer and to evaluate the frequency of established risk factors in breast carcinoma patients and furthermore to compare the findings between premenopausal and postmenopausal women in Pakistan. Materials and Methods: A 6 months (from July 2012 to Dec 2012) cross sectional survey was conducted in Surgical and Oncology Units of Civil Hospital, Karachi. Data were collected though a well developed questionnaire from 105 female patients diagnosed with carcinoma of breast and analyzed using SPSS version 17. Institutional ethical approval was obtained prior to data collection. Results: Out of 105 patients, 43 were premenopausal and 62 were postmenopausal, 99 being married. Mean age at diagnosis was $47.8{\pm}12.4years$. A painless lump was the most frequent symptom, notived by 77.1%(n=81). Some 55.2% (n=58) patients had a lump in the right breast and 44.8%(n=47) in the left breast. In the majority of cases, the lump was present in upper outer quadrant 41.9% (n=44). Mean period of delay from appearance of symptoms to consulting a doctor was $5.13{\pm}4.8months$, from the shortest 1 month to the longest 36 months. Long delay (> 3 months) was the most frequent figure 41.9%. Considering overall risk factors most frequent were first pregnancy after 20 years of age (41%), physical breast trauma (28.6%), lack of breast feeding(21.9%), and early menarche <11 years (19%), followed by null parity (16.2%), consumption of high fat diet (15.2%), family history of breast cancer or any other cancer in first degree relatives (9.5% and 13.3%, respectively). Some of the less common factors were late menopause >54 years (8.6%), use of oral contraceptive pills (10.5%), use of hormone replacement therapy (4.7%),smoking (4.7%) and radiation (0.96%). Significant differences (p<0.005) were observed between pre and post menopausal women regarding history of physical breast trauma, practice of breast feeding and parity. Conclusions: A painless lump was the most frequent clinical presentation noted. Overall age at first child > 20 years, physical breast trauma, lack of breast feeding, early menarche <11 were the most frequent risk factors. Physical breast trauma, lower parity, a trend for less breast feeding had more significant associations with pre-menopausal than post-menopausal onset. Increase opportunity of disease prevention can be obtained through better understanding of clinical presentation and risk factors important in the etiology of breast cancer.

  • Background: Retinoblastoma is a rare type of cancer that usually develops in early childhood. If left untreated it can cause blindness and even death. The aim of this study is to determine sociodemographic and clinical features of retinoblastoma patients and also to determine the treatment pattern and outcome in Malaysia. Materials and Methods: Data for this study were retrieved from the Retinoblastoma Registry of the National Eye Database (NED) in Malaysia. Hospital Kuala Lumpur, Hospital Umum Kuching, Sarawak and Hospital Queen Elizabeth, Kota Kinabalu were the major source data providers for this study. Data collected in the registry cover demography, clinical presentation, modes of treatment, outcomes and complications. Results: The study group consisted of 119 patients (162 eyes) diagnosed with retinoblastoma between 2004 and 2012. There were 68 male (57.1%) and 51 (42.9%) female. The median age at presentation was 22 months. A majority of patients were Malays (54.6%), followed by Chinese (18, 5%), Indians (8.4%), and indigenous races (15.9%). Seventy six (63.8%) patients had unilateral involvement whereas 43 patients had bilateral disease (36.1%). It was found that most children presented with leukocoria (110 patients), followed by strabismus (19), and protopsis (12). Among the 76 with unilateral involvement (76 eyes), enucleation was performed for a majority (79%). More than half of these patients had extraocular extension. Of the 40 who received chemotherapy, 95% were given drugs systemically. Furthermore, in 43 patients with bilateral involvement (86 eyes), 35 (41%) eyes were enucleated and 17 (49%) showed extraocular extension. Seventy-two percent of these patients received systemic chemotherapy. The patients were followed up 1 year after diagnosis, whereby 66 were found to be alive and 4 dead. Sixteen patients defaulted treatment and were lost to follow-up, whereas follow-up data were not available in 33 patients. Conclusions: Patients with retinoblastoma in this middle-income Asian setting are presenting at late stages. As a result, a high proportion of patients warrant aggressive management such as enucleation. We also showed that a high number of patients default follow-up. Therefore, reduction in refusal or delay to initial treatment, and follow-up should be emphasized in order to improve the survival rates of retinoblastoma in this part of the world.
