The meats of tuna Thunnus albacares and swordfish Xiphias gladius are ideal for fish patty production, offering high nutrition and other health benefits. Although red fish meat, including tuna, is added for cost-effectiveness, swordfish white meat is also used, as its aroma resembles that of market-sold beef patties. Here, we assessed the different blending ratios of tuna red meat and swordfish white meat (60:40, 40:60, 20:80, and 0:100) to find the optimal combination for fish patty production. Regarding color, the heated fish patties exhibited increased redness (a*) and yellowness (b*) compared with those of non-heated ones, with similar brightness (L*). The heated patties also scored higher concerning hardness, springiness, gumminess, and chewiness. A higher proportion of swordfish white meat resulted in a softer texture, particularly in patties with a ratio of 40% red meat to 60% white meat. Considering the results of the texture comparison analysis, it is recommended that the texture be improved by increasing the physical property "softness." Sensory evaluations revealed that the addition of white meat led to increased scores in terms of smell, beef taste, texture, and elasticity. These results suggest that swordfish white meat, with improved overall quality, is a suitable raw material for fish patties. Accordingly, the recommended ratio of 20% tuna red meat to 80% swordfish white meat is optimal for fish patty production.

이하영,안창일,조병수,이명연 대한신장학회 1987 Kidney Research and Clinical Practice Vol.6 No.2

In 4 children with steroid-dependent frequently relaps- ing (2) and steroid-resistant (2) minimal change nephrotic syndrome a trial of cyclosporin A treatment was justified. Cyclosporin A was administered for 8 weeks in combination with alternate prednisone. Cyclosporin A was started at an daily oral dose of 6 mg/day. Doses were adjusted to maintain plasma levels between 50 and 150 ng/ml. The results are as follow: Remission was achieved in 2/2 steroid-dependent frequently relapsing and 1/2 steroid-resistant minimal change nephrotic syndrome patients and reduction of proteinuria was achieved in 1/ 2 steroid-resistant patient. Side effects were observed: hypertrichosis (4 pts), skin black-discoloration (4 pts), gastrointestinal intolerance (2 pts), hypertension (2 pts). Renal toxicity of cyclosporin A was not observed. Our experience shows that 1) cyclosporin A can be used to induce a remission in frequently relapsing steroid-dependent and steroid resistant minimal change nephrotic syndrome and 2) low dose short term cyclosporin therapy does not produce nephrotoxicity.

숫자와 글자 순서 판단 수행의 역 거리 효과 및 학업 성취도와의 관계 분석

이하영,조수현 한국인지및생물심리학회 2018 한국심리학회지 인지 및 생물 Vol.30 No.3

The present study examined whether a reverse distance effect (RDE) is consistently observed for ordinality judgment using numbers, Korean letters and the alphabet. RDE refers to a phenomenon in which better performance is observed for judgment on stimuli that are closer to each other. We examined whether performance on these tasks are correlated with academic achievement in math, Korean and English domains. Indeed, RDEs were observed from all three tasks. This result reveals that the order of numbers and letters are similarly processed and is consistent with the results of previous studies reporting RDE. Performance was better for order judgment of numbers compared to Korean letters, and for Korean letters compared to the alphabet. This reveals that ordinality judgment of letters are less efficient compared to numbers and that ordinality judgment in the native language is more efficient compared to a foreign language. Linear regression analysis revealed that ordinality judgment performance using numbers and Korean letters significantly predicted math achievement. All three ordinality judgment performance predicted achievement in Korean and English domains. These results suggest that ordinality judgment of numbers and letters is related to achievement in not only math but also language. The present study is the first to examine the relationship between ordinality judgment performance and language achievement. We hereby propose that ordinal representations may be more domain-general than previously conceived, going beyond their presupposed numerical nature. 역 거리 효과란, 비교 과제에서 자극 간의 거리가 가까울수록 더 좋은 수행을 보이는 현상을 말한다. 본 연구에서는 숫자, 한글 자음/모음, 영어 알파벳을 사용한 순서 판단 시 역 거리 효과가 나타나는지를 확인하고, 각 과제의 수행과 수학, 국어, 영어 성취도 간의 관계를 분석하였다. 연구 결과, 모든 순서 판단 과제에서 역 거리 효과가 나타나 숫자와 글자의 순서 정보가 유사하게 처리됨을 확인하였다. 참가자들은 숫자 과제를 한글 과제보다, 한글 과제를 영어 과제보다 더 우수하게 수행하였다. 이는 숫자와 비교할 때 글자 순서 판단은 상대적으로 익숙하지 않은 과제이기 때문인 것으로 해석할 수 있다. 또한, 이 결과를 통해 외국어와 비교할 때 모국어 글자 판단이 더 수월하였음을 알 수 있다. 회귀분석 결과, 숫자, 한글, 알파벳 순서 판단 과제의 수행이 수학, 국어, 영어 성취도를 유의하게 예측하였다. 이러한 결과는 숫자와 글자 순서 판단 과제의 수행이 수학만이 아닌 언어 영역의 학업 성취도와도 밀접한 관계가 있음을 시사한다. 본 연구는 순서 판단 과제의 수행과 언어 영역 성취도 간의 관계를 살펴본 최초의 연구로서, 순서 판단 능력이 수학 및 수학 외 언어 영역의 성취와도 밀접한 관계가 있음을 시사한다.

대안학교를 선택한 장애학생 부모의 경험과 그 의미

이하영,임경원 한국정서행동장애학회 2017 정서ㆍ행동장애연구 Vol.33 No.2

The purpose of this study was to explore the experiences and meaning of parents who chose alternative schools for their children with special needs and find implications for special education based on public education. For the purpose, 6 parents participated in the interviews and data were analysed in a comprehensive analysis procedure based on pragmatic eclecticism. The results were identified in three upper categories and 12 lower categories based on 35 meaning units. The parents thought the inclusive education is only possible during the lower grades in elementary schools. They said that the inclusive class teacher has a significant role for the inclusive education and children with disabilities have difficulties in relationship with their friends. These made the parents have chosen alternative schools. They met teachers who were passionate in education. There were various educational experiments in the alternative schools. Although their children had peer relationships and found stability, the schools seem to require supports related to special education. 이 연구의 목적은 대안학교를 선택한 학부모들의 경험과 그 의미를 알아보고 제도권교육 중심의 특수교육에 주는 시사점을 알아보는데 있었다. 이를 위해 자녀를 대안학교에 보낸 6명의 학부모 참여자를 상대로 면담을 실시하였으며, 면담 자료는 포괄적 분석절차를 통해 분석하였다. 연구 결과, ‘제도권교육(통합교육)이라는 견고한 성’, ‘역동적인 대안학교: 모든 것이 가능한 곳인가?’, ‘부모: 자녀의 행복을 찾아 미지의 세계로’의 3개 상위범주와 12개의 하위범주, 35개의 의미단위가 도출되었다. 부모들은 저학년에서는 통합교육이 가능하지만 입시교육 위주의 우리나라 교육현장의 특성상 지속적인 통합교육은 어렵다고 하였으며, 통합교육에 있어서 담임교사의 역할이 결정적이라고 하였다. 물리적 통합에 그치고 있는 우리나라 통합교육의 현실적 한계로 인해 장애학생은 또래관계에도 어려움을 겪고 있는 것으로 나타났다. 이로 인해 제도권 교육에서 특수학교밖에 대안이 없던 부모들이 대안학교를 찾게 된 것으로 보인다. 부모들은 대안학교에서 다양한 교육실험과 열정적인 교사들을 경험했다. 자녀들은 또래관계를 형성하며 안정을 찾기도 했지만 대안학교에도 특수교육과 관련된 여러 제도적 지원이 필요한 것으로 나타났다.

Purpose: Glucose transporter protein isoform 1 (GLUT1) has been introduced to diagnose the hemangiomas of infancy. We investigated the usefulness of several immunohistochemical markers, including GLUT1, as related with the clinical and radiologic findings for making the diagnosis of adult subcutaneous vascular lesions in the head and neck. Materials and Methods: The 24 patients who underwent operations for soft tissue vascular lesion during the previous 7 years were included in this study. We analyzed the angiographic data, the clinical data and the immunohistochemical study results, including the GLUT1, S-100 protein and Movat pentichrome staining. Results: Twenty-two patients were confirmed to have arteriovenous malformation (AVM) and two hemangiomas, respectively. The number of lesions with positive Movat pentichrome, S-100 and GLUT1 staining in the patients with AVM and those patients with hemangioma were 22/22, 20/22 and 0/22, and 0/2, 0/2 and 0/2, respectively. For the 22 patients with AVMs, eight had a soft tissue vascular lesion at birth, 13 had cutaneous change and 15 had a change of the size of the lesion. For the 2 patients with one hemangioma each, neither patient had a soft tissue vascular lesion at birth, and both patients had cutaneous change and a change of the size of the lesion. The angiograms revealed a focal hypervascular mass (19/24) or diffuse staining (5/24) without showing significant features for making the definitive differential diagnosis. Conclusion: Our study revealed that none of the patients with AVM or hemangioma had GLUT1 positivity, and an arteriovenous malformation was more common than the adult-type hemangioma.

Enhancement of Self-Healing Property by Introducing Ethylene Glycol Group into Thermally Reversible Diels-Alder Reaction Based Self-Healable Materials

이하영,차상호 한국고분자학회 2017 Macromolecular Research Vol.25 No.6

Herein, the effect of chain mobility on the efficiency of self-healing was investigated based on thermally reversible Diels-Alder reaction. Ethylene glycol group was chosen as the functional group for increasing chain mobility of the furan functionalized polymethacrylate and bismaleimide, respectively. From the thermal analysis of the films prepared with various combinations between furan functionalized polymethacrylates and bismaleimide, it was found that glass transition temperature of films decreased with increasing the content of ethylene glycol group. Comparing the state of film before and after the self-healing process by optical microscope images, it was also confirmed that the film prepared with polymer and bismaleimide having high ratio of ethylene glycol group (FEEMA55 and bismaleimide- 1) has high self-healing efficiency. Therefore, the improving mobility by the introduction of ethylene glycol group plays an important role for the enhancement of self-healing property.

전문대학 교양교육의 현황과 과제

이하영,이승철 한국인격교육학회 2022 인격교육 Vol.16 No.1

This study aims to examine the following introductions to derive improvement tasks for the operation of the current vocational college liberal arts curriculum. First, I would like to examine the recent policy trends that have led to the direction of a dualized liberal arts education currently aimed at junior colleges, focusing on "core competencies" and National Competency Standards (NCS). Second, I would like to examine cases of improving liberal arts education at individual universities that attempt to converge the government's policy orientation and the original orientation of liberal arts education in any way under the current conditions. Finally, through the preceding discussion, I would like to present some meaningful implications for the task of improving the operation of the liberal arts curriculum of junior colleges in the future. 본 연구는 현재 전문대학 교양교육과정 운영에 대한 개선 과제를 도출하기 위하여 다음의 소개 사항을 살펴보고자 한다. 첫째, 현재 전문대학이 지향하는 이원화된 교양교육의 방향성을 초래한 최근의 정책적 흐름을 ‘핵심역량’과 ‘국가직무능력표준(NCS)을 중심으로 살펴보고자 한다. 둘째, 현재적 여건 속에서 정부의 정책적 지향과 교양교육의 본래적 지향을 어떤 방식으로건 융합하려는 개별 대학의 교양교육 개선 사례를 살펴보고자 한다. 마지막으로 앞선 논의를 통해 향후 전문대학 교양교육과정 운영의 개선과제에 대한 몇 가지 의미 있는 시사를 제시하고자 한다.
