목적: 편측 안면화염혈관종과 동측 녹내장이 있는 환아에서 무증상 반대 눈의 안압과 유두함몰비에 대해 고찰하고자 한다. 대상과 방법: 1996년 9월부터 2020년 5월까지 본원 소아안과에서 한쪽 눈 안면화염혈관종 녹내장을 진단받은 35명의 의무기록을 후향적으로 분석하였다. 무증상 반대 눈의 임상특성(즉, 안압과 유두함몰비)을 안면화염혈관종과 녹내장이 모두 없는 대조군(35명 35안)과 비교하였다. 결과: 한쪽 눈 안면화염혈관종 녹내장군의 녹내장 진단 시 평균 연령은 0.56 ± 0.99세(범위, 0.08-4세)였다. 녹내장 진단 시 반대 눈의 평균 안압은 16.68 ± 5.73 mmHg (범위, 9-22.9)였고, 유두함몰비는 0.37 ± 0.14 (범위, 0.15-0.80)였다. 마지막 진료 시(평균 연령, 11.2 ± 7.5세) 평균 안압은 14.14 ± 6.29 mmHg (범위, 8.1-26.7)였고, 유두함몰비는 0.37 ± 0.12 (범위, 0.26-0.82)였다. 대조군(평균 연령, 11.2 ± 7.4세)과 비교했을 때 평균 안압에는 유의한 차이가 없었으나(14.14 ± 6.29 mmHg vs. 14.57 ± 2.49 mmHg, p=0.712) 유두함몰비는 대조군에 비해 유의하게 컸다(0.37 ± 0.12 vs. 0.30 ± 0.08, p=0.014). 결론: 한쪽 눈 안면화염혈관종 녹내장을 진단받은 환아에서 무증상 반대 눈의 유두함몰비가 대조군에 비해 증가되어 있었다. 안면화염혈관종 녹내장이 한쪽 눈에서 진단된 경우 반대 눈에 녹내장 발생 위험이 증가하는지에 대한 후속 연구가 필요하다. Purpose: To investigate the clinical features of non-affected fellow eyes in patients with unilateral facial port-wine stain (PWS) and ipsilateral secondary glaucoma. Methods: We performed a retrospective analysis of the medical records of 35 patients with unilateral facial PWS glaucoma and those of controls (35 subjects without both facial PWS and glaucoma) between September 1996 and May 2020. We noted patients’ age at the glaucoma diagnosis (for unilateral facial PWS glaucoma patients) or at the initial examination (for controls), cup-to-disc ratio (CDR), and intraocular pressure (IOP). We compared the clinical features between the glaucoma-free eyes in patients with unilateral facial PWS glaucoma and the controls. Results: The mean age at the glaucoma diagnosis for unilateral facial PWS glaucoma patients was 0.56 ± 0.99 years (range, 0.08-4). The mean IOP of the glaucoma-free eyes was 16.68 ± 5.73 mmHg (range, 9-22.9), and the mean CDR was 0.37 ± 0.14 (range, 0.15-0.80) at glaucoma diagnosis. The mean IOP of the glaucoma-free eyes was 14.14 ± 6.29 mmHg (range, 8.1-26.7), and the mean CDR was 0.37 ± 0.12 (range, 0.26-0.82) at final examination. When comparing glaucoma-free eyes of the unilateral facial PWS glaucoma patients with the control group (mean age, 11.2 ± 7.4 years), the mean CDR was significantly greater (0.37 ± 0.12 vs. 0.30 ± 0.08; p = 0.014) but there was no significant difference in the mean IOP (14.14 ± 6.29 mmHg vs. 14.57 ± 2.49 mmHg; p = 0.712). Conclusions: The glaucoma-free eyes of unilateral facial PWS glaucoma patients showed greater CDR compared to the non-facial PWS and non-glaucoma controls. Additional longitudinal studies are needed to investigate the clinical course of those eyes, whether the risk of developing glaucoma is increased.

As the beauty service industry becomes segmented and specialized into the hair, makeup, skin care, and nail art fields, it is poised to become a main area in the service industry; however, despite its consistent increase in size, there is a need for reasonable marketing strategies with the ensuring of talented persons and a reduction of service fees. Consequently, this study aimed to conduct comparative research into the current use of beauty services aimed at the spouses and children of customers who use beauty services. First, as a result of carrying out a cross analysis of a comparison in the current use of research subjects, their spouses, and children regarding the most used treatment and the most desired to use treatment among the three groups, it was discovered that they were in the order of a perm and coloring. For spouses, the order was coloring and cut, while for children it was cut. Concerning the average treatment cost per treatment of the three groups, the research subjects were found to spend 40,000 won or over, their spouse over 10,000 won to less than 20,000 won, and their children less than 10,000 won. In case of the average cost per treatment of a general perm, the research subjects were discovered to spend over 60,000 won to less than 80,000 won, their spouses over 20,000 won to less than 40,000 won, and their children less than 20,000 won. Regarding the payer for the treatment cost of the three groups, the payer for the research subjects was discovered to be their parents and the research subjects, for the spouses it was themselves, and for their children it was themselves. From this, it was shown that the use pattern of beauty services among the research subjects, their spouses, and their children was different. In reviewing the above results, in the beauty service industry, it is necessary to identify the characteristics of family customers accurately; thus, a suitable service may be offered to their satisfaction. In addition, if beauty service managers utilize technical service and management marketing suited to family customers, this will be a foundation for an increase in sales from long-term customers.

본 연구에서는 저온기에 참외재배 단동 플라스틱 온실에서 지붕 환기팬을 이용하여 환기할 때 작물에 스트레스를 적게 주면서 바깥 공기를 하우스 내부로 균일하게 유입할 수 있는 방법으로 하우스 전체길이에 대해 측창 안쪽부분에 비닐을 부착하는 방법을 개발하였다. 지면으로부터 측창이 최대한 열렸을 때 높이의 10cm 아래까지 비닐을 설치하였다. 측창 개선에 의한 온실 환경 개선 및 참외 수량증대 효과를 검증하기 위하여 개선 측창형태와 관행의 측창형태를 비교하였다. 2017년 2월 25일 까지는 두 시험구 모두 환기를 하지 않았는데, 2월 중순 하우스 내 기온이 40℃를 넘어섰다. 따라서 2월 중순부터는 하우스 환기를 시작해야 할 것으로 판단된다. 대조구에서의 기온이 4월 하순부터 30℃를 넘어섰다. 그러므로 측창 안쪽에 부착한 비닐을 4월 하순, 늦어도 5월 상순에는 제거해야 할 것으로 판단된다. 4월 중순에 처리구에서의 지온은 생육 적온 범위인 20℃를 넘어선데 비해 대조구에서는 여전히 20℃보다 낮게 나타났다. 4월 하순이 되어서야 대조구의 지온도 20℃를 넘어서는 것으로 나타났다. 전기사용량은 처리구 47.2kWh, 대조구 48.3kWh로 처리 간에 큰 차이를 보이지 않았다. 처리구에서의 참외 상품수량은 5,094kg으로 대조구 4,113kg에 비해 23.9% 많았다. 상품과율은 처리구 73.5%, 대조구 73.9%로 차이가 없었다. In this study, the method to attach plastic film on the side vent from inside of greenhouse for the entire length was developed as the way to make crops less stressful while uniformly getting outside air into the greenhouse when ventilating using roof ventilation fans at single-span plastic greenhouse for oriental melon in a low-temperature period. The plastic film was installed from ground to 10cm below from the height where side vent is fully opened. In order to verify that the improved side vent can improve greenhouse environment and fruit yield, it was compared with the control plot of conventional side vent. Both greenhouses were not ventilated until February 25th, 2017. Air temperature in both greenhouses exceeded 40℃ in mid February. Therefore, it is judged that the greenhouse should be ventilated from mid February. Air temperature in the control plot exceeded 30℃ from late April. Therefore, it is judged that the plastic film attached to the inside of side vent should be removed in late April, or in early May at the latest. Soil temperature in the treatment plot in the mid Aril exceeded 20℃, which is suitable for growth, while that in the control plot was still below 20℃. Soil temperature in the control plot finally exceeded 20℃ in late April. The consumption of electricity was 47.2 kWh in the treatment plot, and 48.3 kWh in the control plot, which was no significant difference. The marketable yield of oriental melon in the treatment plot was 5,094kg, which was 23.9% more than that in the control plot, 4,113kg. The marketable fruit ratio was 73.5% in the treatment plot, and that in the control plot was 73.9%, which was no significant difference.

Molecular Beam Epitaxy(MBE)법으로 성장된 In_xGa_(1-x)As/GaAs 에피층에 대해 photoreflectance (PR)실험을 통해 특성을 조사하였다. PR 측정결과 성장된 In_xGa_(1-x)As 에피층의 띠간격 에너지(E。) 신호가 시료의 변형(strain)에 의해 heavy-hole(E。(HH))과 light-hole(E。(LH))로 분리되어 관측되었다. 에피층의 조성과 변형은 각각 시료에서의 E。(HH) 및 Eo(HH)와 Eo(LH)신호의 에너지 차이를 이용하여 구하였다. 또 160 K이하의 온도에서는 Eo(LH)의 신호가 사라짐을 볼 수 있었다. Franz-Keldysh oscillation(FKO) 피크로부터 계산되어진 InGaAs/GaAs 계면전장 (E)은 In 조성의 증가에 따라 0.75×10^5 V/㎝에서 2.66×10^5 V/㎝로 증가하였다. In 조성이 x=0.09인 시료에 대한 PR신호의 온도의존성 실험에서 Varshni 계수와 Bose-Einstein 계수들을 각각 구하였다. Photoreflectance (PR) measurents have been performed on In_xGa_(1-x)As/GaAs grown by molecular beam epitaxy (MBE). Bandgap (E。) of In_xGa_(1-x)As epilayer measured from PR was separated as heavy-hole (E。(HH)) and light-hole (E。(LH)) by strain effect. The compositions and the strains of epilayer were obtained from the energy value of E。(HH) and from enegy difference of E。(HH) and E。(LH), respectively. In addition, the PR signal of E。(LH) was diminished below 160 K. The interface electric field (E) of InGaAs/GaAs was increased from 0.75×10^5 V/㎝ to 2.66×10^5 V/㎝ as In composition increased, which was calculated from Franz-Keldysh oscillation (FKO) peaks. As the temperature dependence of the PR signal at x=0.09 sample, we obtained Varshni and Bose-Einstein coefficients.

전 세계적인 지구온난화의 위협에 대응하고자 세계 각국은 신재생 에너지의 확산, 탄소 배출 감소 등을 추진하고 있다. 또한, UN의 SDGs에도 포함된 기후변화에 맞서기 위한 노력으로 글로벌 자동차 제조사들은 향후 10년내에 전기자동차로의 전면 전환을 추진하고 있다. 전기자동차는 탄소 배출 감소를 위한 유용한 수단이 될 수 있으나, 충전용 전기를 생산하는 단계에서 발생하는 탄소의 저감을 위해서는 친환경 신재생 에너지를 이용한 발전시스템이 요구된다. 본 연구에서는 아프리카 탄자니아에 설립된 태양광 발전소와 통합된 스마트 전기 모빌리티 운영 시스템에 대한 비전을 제안한다. 아두이노 컴퓨팅 장치를 기반으로 하는 스마트 모니터링 및 통신 기능을 적용하여 전기자동차 또는 전기 오토바이의 배터리 잔존용량, 배터리 상태, 위치, 속도, 고도, 도로 상태 등의 정보를 모니터링한다. 또한, 주변의 독립형 태양광 발전소 인프라와 통신하여 주행가능거리를 예측하고 충전 스케쥴 및 목적지까지의 경로 최적화를 수행하는 시나리오를 제시한다. 제안된 시스템의 구현 가능성은 전기 오토바이의 시험운행을 통해 검증되었다. 탄자니아에서 운영될 전기 모빌리티 시스템은 현지의 환경과 특성을 고려하여 친환경성, 경제성, 운용 용이성, 호환성 등의 요소가 고려되어야 한다. 본 연구에서 제안하는 스마트 전기 모빌리티 운영 시스템은 SDGs의 이행을 위한 중요한 기반이 될 수 있을 것이다. To respond to the threat of global warming, countries around the world are promoting the spread of renewable energy and reduction of carbon emissions. In accordance with the United Nation’s Sustainable Development Goal to combat climate change and its impacts, global automakers are pushing for a full transition to electric vehicles within the next 10 years. Electric vehicles can be a useful means for reducing carbon emissions, but in order to reduce carbon generated in the stage of producing electricity for charging, a power generation system using eco-friendly renewable energy is required. In this study, we propose a smart electric mobility operating system integrated with off-grid solar power plants established in Tanzania, Africa. By applying smart monitoring and communication functions based on Arduino-based computing devices, information such as remaining battery capacity, battery status, location, speed, altitude, and road conditions of an electric vehicle or electric motorcycle is monitored. In addition, we present a scenario that communicates with the surrounding independent solar power plant infrastructure to predict the drivable distance and optimize the charging schedule and route to the destination. The feasibility of the proposed system was verified through test runs of electric motorcycles. In considering local environmental characteristics in Tanzania for the operation of the electric mobility system, factors such as eco-friendliness, economic feasibility, ease of operation, and compatibility should be weighed. The smart electric mobility operating system proposed in this study can be an important basis for implementing the SDGs climate change response.

N/A Objectives: A prospective study was performed to find out the correlation between neutrophil, eosinophil and eosinophilic cationic protein (ECP) the granular protein in eosinophil - and smoking history and pulmonary function change, Methods: In this study there were seventy smokers and seventy lifetime nonsmokers. None of them had the history of atopy, or the evidence of parasitic infestation. Smoking history, spirometric pulmonary function test and blood samples for CBC, serum ECP were analyzed. Results: 1) Eosinophil and neutophil count was elevated in the smokers compared with the nonsmokers. 2) Serum ECP was elevated in smokers and the magnitude of this increase was greater than that of eosinophil count. 3) In the smokers, there was a direct proportional correlation between serum ECP and FEV1, but inverse proportional correlation between neutophil count and FEV. 4) In the smokers, neutrophil count was elevated regardless of FEV value. 5) The level of serum ECP well correlated with the daily tobacco consumption but not with the duration of smoking or pack-year consumption. Conclusion: Incresed neutrophil count, decreased eosinophil count and decreased serum ECP level could be useful in the understanding of pathophysiology of lung parenchymal destruction in smokers.

목적: 저자들은 양안 상사근마비 환자에서 회선편위의 교정을 위해 변형된 하라다-이토수술 및 Mendez 링을 이용한 술 중 조정술을 시행하여 만족스러운 수술 결과를 얻은 사례를 소개하고자 한다. 증례요약: 47세의 남자 환자가 뇌출혈 이후 발생한 양안 복시를 주소로 내원하였다. 양안 상사근마비로 진단하였고, 이중마독스막대검사상 양안에 각각 20° 외회선이 확인되어 양안 회선복시에 대하여 6개월 경과 관찰 후 수술적 교정을 시도하였다. 외회선 교정량을 확인하기 위해 각막윤부 6시와 12시에 마커를 이용하여 표시를 한 후 상사근에 변형된 하라다-이토수술을 시행하였고, 이후 Mendez 링을 각막윤부에 위치하도록 하여 내회선 정도로 확인하였다. 각각 30° 내회선을 목표로 하여 우안에 상사근절제술을 5 mm 추가하였다. 술 후 6개월째 복시를 호소하지 않았으며 회선편위는 관찰되지 않았다. 결론: 변형된 하라다-이토수술 및 Mendez 링을 이용한 술 중 조정술을 통하여 내회선 목표치에 정량적으로 도달할 수 있었으며, 원하는 교정 효과를 얻을 수 있었다. Purpose: We report a case of using a modified Harada-Ito procedure with intraoperative adjustment via a Mendez ring in a patient with bilateral superior oblique palsy, resulting in satisfactory postoperative outcomes. Case summary: A 47-year-old male patient presented with bilateral diplopia after cerebral hemorrhage. Bilateral superior oblique palsy was diagnosed, and double Maddox rod tests confirmed 20° of excyclotorsion in both eyes. After 6 months of observation, surgical correction was attempted. To check the amount of cyclodeviation, a modified Harada–Ito procedure was performed on the superior oblique muscle after marking at the 6 and 12 o clock positions of the corneal limbus. Following the procedure, a Mendez ring was placed on the limbus to check for the amount of incyclotorsion. Thirty degrees of incyclotorsion was aimed at both eyes, and a 5-mm resection of the right superior oblique tendon was performed for additional correction. There was no complaint of diplopia at 6 months postoperatively, and no deviation was observed. Conclusions: A modified Harada-Ito procedure with intraoperative adjustment using a Mendez ring effectively corrected excyclotorsion with torsional diplopia.
