조승환,정재현,박범주,신완선 한국경영과학회 2023 經營 科學 Vol.40 No.1

Existing SW competency models and development platforms are fragmented, and researched and implemented mainly by suppliers such as elementary, middle and high schools and universities. This results in competency mismatches including weak connection with companies, which generate the biggest demand for SW workforce. From the perspective of companies which are desperate about proactive response to rapid technological changes in the era of the fourth industrial revolution, existing models and platforms failed to present appropriate alternatives for fostering SW talent and genuine competency. Backed by the cases of domestic IT companies (home appliances / information and communication / semiconductor fields), this paper presented the directions of cultivating SW workforce envisioned by companies. The proposed directions have been integrated into a corporate SW competency model to ensure the organic relationship in the process of talent development taken place in universities and companies. By applying the leadership pipeline, which was mainly used for succession planning, to a technology field of SW, this study also derived a differentiated SW competency model that blurs the boundary between technology and business management. In particular, it was possible to secure the practicality of the step-wise SW competency model by mapping out the necessary competencies based on the roles of SW workforce by growth stage and the ideal characteristics of talent required by the private sector. In addition, it was possible to verify its effectiveness by creating and applying a SW programming test based on the derived SW competency model.

조승환,김수진 대한안과학회 2015 대한안과학회지 Vol.56 No.6

목적: 머리 수상 후 두통, 안구운동장애 및 복시를 주소로 내원한 소아가 내직근의 감돈을 동반한 안와내벽골절을 진단 받고 수술적 치료를 받은 1예를 경험하였기에 이를 보고하고자 한다. 증례요약: 기저질환이 없는 만 16세 남자 환자가 내원 1일 전 음주 상태로 아파트 계단에서 넘어진 후 두통 및 우측 안구의 심한 운동장애와 복시, 오심이 지속되어 수상 다음 날 내원하였다. 수상 당시 음주 상태로 기억이 없으나 후두부 부종이 만져진다고 하였다.안와 주위에 혈종이나 부종은 없었고, 세극등현미경 검사에서도 우안 비측 결막에 경도의 충혈 외에 특이소견은 관찰되지 않았다.제일안위에서 18프리즘디옵터의 외사시를 보였고, 안구운동검사에서 우안의 심한 내전 및 경도의 외전 장애가 관찰되었으며, 안구운동 시 통증을 호소하였다. 뇌자기공명영상검사에서 두개강내 이상소견은 보이지 않았고, 뇌자기공명영상검사와 부비동 전산화단층촬영에서 우안 안와내벽의 골절편에 연부 조직 및 근육이 감돈되어 있는 들창문형의 안와내벽골절 소견을 확인할 수 있었다. 내원 48시간 이내에 안와골절 정복술을 시행하였고, 수술 50일 이후에 안구운동장애와 복시는 거의 회복되었다. 결론: 안와 주변에 대한 외상의 병력이 불분명하고 안와 주위에 혈종이나 부종 등의 소견을 보이지 않는 소아 안와골절의 경우 뇌병변으로 오인할 수 있으므로, 소아에서 외상 후 안구운동제한과 복시, 오심, 구토 등의 증상이 동반된다면, 신경학적 평가 외에도 안와골절에 대한 감별 진단을 반드시 시행해야 할 것이다. Purpose: To report a case of pediatric medial wall blowout fracture with entrapment of medial rectus muscle which can be easily misdiagnosed as a cerebral lesion. Case summary: A 16-year-old male visited our clinic with headache, severe restriction of his right eye movement, and diplopia after a head injury due to falling occurring 1 day before evaluation. The patient was inebriated at the time of the accident and could not recall the event but occipital hematoma was palpable. Periorbital ecchymosis or edema was not observed with minimal soft tissue injury except mild conjunctival injection on slit-lamp examination. The patient had an 18 prism diopter exodeviation at primary position and severe medial and mild lateral gaze limitation in his right eye. Brain magnetic resonance imaging (MRI) showed no specific cerebral findings although trapdoor orbital medial wall fracture with incarceration of soft tissue and medial rectus muscle at the medial wall fracture site of his right eye was observed. Within 48 hours from the first evaluation, the blowout fracture was repaired and 50 days postoperatively, right eye gaze limitation and diplopia were nearly recovered. Conclusions: A case of pediatric blowout fracture with uncertain injury location, periocular ecchymosis, or edema absent could be misdiagnosed as a cerebral lesion. If a pediatric patient is experiencing gaze limitation, diplopia, nausea, or vomiting after trauma, neurological examination as well as evaluation for blowout fracture should be performed.

Gadolinium-doped Ceria/Magnesia (CGO/MgO) 복합체 전해질의 전기적 특성 분석

조승환,김도경,Jo, Seung-Hwan,Muralidharan, P.,Kim, Do-Kyung 한국재료학회 2008 한국재료학회지 Vol.18 No.9

Composites of gadolinium-doped ceria/magnesia(CGO/MgO) were synthesized and characterized for the electrolytes of intermediate temperature solid oxide fuel cells. XRD and SEM results revealed that composite electrolytes consisted of their own phases after sintering at $1400^{\circ}C$ without noticeable solid solution of Mg into CGO. As the MgO content increased, the total electrical conductivity decreased, which might be attributed to the decrease of grain boundary conductivity, possibly due to the lowering of the continuity of the CGO grains and blocking effects of the insulating MgO phase. The space charge effect may not be a significant factor to affect the electrical conductivity of the CGO/MgO composites.

조승환,이상홍,이현준 대한고관절학회 2016 Hip and Pelvis Vol.28 No.1

Purpose: This study aims to determine the correlation between the fracture patterns and the complications in patients with femoral neck fracture treated with internal fixation. Materials and Methods: The study comprises 45 patients with femoral neck fracture treated with multiple screws or compression hip screw between May 2008 and April 2012. The mean age was 48 years at the time of the surgery and the mean duration from initial injury to surgery was 20 hours. The fracture patterns were identified according to the anatomical location, the Garden classification and the Pauwels classification. The occurrence of nonunion and avascular necrosis were reviewed with clinical results including Harris hip score and Lunceford hip function test. The correlation between the fracture pattern and occurrence of complications were analyzed. Results: Fracture site union was achieved in 40 hips with the average union time of 17 weeks. Five nonunions occurred which showed high likelihood to occur in subcapital type, displaced (Garden stage III or IV) and Pauwels type III fractures (P<0.05). Avascular necrosis was developed in 10 hips which was mostly in subcapital type and Pauwels type III fracture but no statistical significance was found (P>0.05). The mean Harris hip score was 91 points, and Lunceford functional results were excellent in 15 hips, good in 24, fair in 4 and poor in 2. Conclusion: There was high risk of nonunion in subcapital type fracture, displaced fracture (Garden stage III and IV) and vertically oriented fracture (Pauwels type III). Careful attention is needed in these fracture types.
