역사적 제도주의 관점에서 본 청년정책 형성과정 : 청년기본법 도입을 중심으로

김하은,이명현 사회복지정책실천회 2023 사회복지정책과 실천 Vol.9 No.1

This study aims to derive policy implications by analyzing the making process of youth policy from the perspective of historical institutionalism. In particular, the integrative approach of structure-institution-action can explain institutional change through external and internal factors. The results of this study are as follows. First, in the structural context, various socio-economic crises surrounding youth have been accumulated as potential problems. In addition, there was a change of power in some local governments and central government at an initiative trigger for institutional change. Secondly, in the institutional context, there were institutional constraints such as policy ideology emphasizing individual responsibility and self-help, employment policy and law. On the other hand, cooperative governance with youth groups was formed in some local governments, which led to the introduction of policies to guarantee the fundamental rights of youth. Third, in the action factor, there were youth organizations that emphasized guaranteeing the fundamental rights of all youth, the national assembly that insisted introduction of effective policies through coordination and management, the government that asserted comprehensive policy formation, and experts. Even though institutional constraints, they tried to change the policy by communicating in various ways. 본 연구의 목적은 청년정책 형성과정을 역사적 제도주의 관점에서 분석함으로써 정책적 함의를 도출하는 것이다. 특히 역사적 제도주의 접근 중에서도 Mahoney & Snyder(1999)의 통합적 접근을 통해 구조-제도-행위자 수준을통합적으로 고려하고자 하였다. 분석 결과, 구조적 맥락에서는 청년을 둘러싼 다양한 사회경제적 위기 속에서 일부 지방정부 단체장의 변화와 정권교체가 촉발기제 및 결정적 분기점으로 작용하였다. 제도적 맥락에서는 개인의 책임과 자조를 강조하는 복지이념, 일자리 중심의 정책이 제도적 제약이되는 한편, 일부 지방정부 중심으로 청년단체와의 협력적 거버넌스 형성 및청년기본권 보장을 위한 정책의 도입 등이 변화의 기회가 되었다. 행위자에는 불평등을 극복하고 모든 청년의 기본권 보장을 강조했던 청년단체, 조정및 관리를 통해 실효성 있는 정책 도입을 강조했던 국회, 종합적인 정책적대응에 공감한 정부, 전문가가 있었다. 이들은 제도적 제약에도 불구하고 다양한 방식으로 소통함으로써 정책을 변화시키고자 하였다. 끝으로, 이러한분석결과를 바탕으로 정책적 함의를 제시하였다.

Red Pepper (Capsicum annuum L.) Seed Extract Decreased Hepatic Gluconeogenesis and Increased Muscle Glucose Uptake In Vitro

김하은,조계원,정정호,박기범,류융선,Knowledge Mudhibadhi Moyo,김현경,고광웅 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.7

Red pepper seed, a by-product of red pepper, has been reported to have antioxidant and antiobesity activities. However, its role in diabetes has not yet been highly investigated. Glucose homeostasis is mainly maintained by insulin, which suppresses glucose production in the liver and enhances glucose uptake in peripheral tissues. In this study, we investigated the underlying mechanisms through which red pepper seed extract (RPSE) affects glucose production in AML12 hepatocytes and glucose uptake in C2C12 myotubes. RPSE reduced glucose production in a dose-dependent manner in AML12 cells. The levels of glucose 6 phosphatase, phosphoenolpyruvate carboxykinase, and critical enzymes for hepatic gluconeogenesis were decreased by RPSE. Gluconeogenesis regulating proteins, Akt and forkhead box protein O1, were also activated by RPSE. In addition, RPSE increased glucose uptake in C2C12 via inducing translocation of glucose transporter type 4 from cytosol to plasma membrane. Analysis of the insulin-dependent pathway showed that the activities of insulin receptor substrate 1, phosphatidylinositol 3-kinase, and Akt were significantly stimulated by RPSE. In conclusion, RPSE might improve glucose homeostasis by reducing hepatic gluconeogenesis and increasing peripheral glucose uptake. Results obtained also suggest that RPSE can be a compelling antidiabetic nutraceutical.

The purpose of this study is to find out the effects of function-centered comprehensive intervention on immediate echolalia and appropriate communication responses of a young child with autism. A participant in this study was a 5 years-old boy with autism. The comprehensive intervention based on functional assessment was planned: antecedent intervention, alternative response teaching, and consequence intervention. Three appropriate communication responses included labeling, yes/no answering, and describing objects’ function/action. The study applied AB design to examine the effect on immediate echolalia, and a multiple baseline design across behaviors which proceeded baseline, intervention and maintenance to find out the change of appropriate communication responses. Data was collected using event recording and then rates of immediate echolalia and appropriate communication responses was calculated. The results of the study are as follows. Firstly, as the result of function-centered comprehensive intervention, rates of immediate echolalia decreased from 98% to 41.8% on average. Secondly, improvement rates of three appropriate communication responses increased: Labeling 75.7%, yes/no answering 66%, and describing objects’ function/action 69.8%. Analysis on level, trend, immediacy, and PND showed that function-centered comprehensive intervention has a high effect on improving the three appropriate communication responses. 본 연구의 목적은 기능중심의 종합적 중재가 자폐성장애 유아의 즉각반향어와 적절한 의사소통 반응에 미치는 효과를 살펴보는데 있었다. 연구 참여 유아는 자폐성장애를 가진 만 5세 남아 1명이었다. 즉각반향어 기능평가에 근거한 선행사건 중재, 대체행동 교수, 후속사건 중재로 구성된 기능중심의 종합적 중재가 고안되었다. 대체행동으로서 적절한 의사소통 반응은 명명하기, 네/아니요 대답하기, 사물의 기능/행위 표현하기로 각각 조작적 정의하였다. 즉각반향어의 변화를 살펴보기 위해 AB설계를 사용하고, 중재 전후 반향어 기능평가를 실시하였다. 적절한 의사소통 반응에 대한 중재 효과는 행동간 중다기초선 설계를 사용하여 알아보았으며, 기초선, 중재, 유지 단계에서의 변화를 분석하였다. 자료는 사건기록법을 이용하여 수집한 후 즉각반향어 비율과 적절한 의사소통 반응 비율을 각각 산출하였다. 연구 결과는 다음과 같다. 첫째, 기능중심의 종합적 중재 결과 즉각반향어는 평균 98%에서 41.8%로 감소하였고 그 변화는 지속적으로 감소하는 경향을 보였다. 또한 즉각반향어의 기능 변화에 있어 중재 전에는 7가지 기능이 모두 나타난 반면 중재 후에는 주고받기, 긍정대답, 비초점 기능만이 15% 비율로 나타났다. 둘째, 적절한 의사소통 반응의 경우 명명하기 75.7%, 네/아니요 대답하기 66%, 사물의 기능/행위 표현하기 69.8%의 높은 향상률을 보였다. 구간 간 자료의 경향, 자료 변화의 즉시성, 자료의 비중첩률에 대한 시각적 분석 역시 기능중심의 종합적 중재가 반향어를 감소시키고 3가지 적절한 의사소통 반응을 향상시키는데 높은 효과가 있음을 보여주었다. 이러한 연구 결과는 기능중심의 종합적 중재가 자폐성장애 유아의 즉각반향어를 감소시키는 동시에 적절한 의사소통 반응을 증가시키기 위한 효과적인 중재로 활용될 수 있음을 시사한다.

The purpose of this study was to investigate the current status of work-related upper extremity musculoskeletal pain in baristas and to identify the elements that are related to pain. The questionnaires were distributed to 100 workers in 63 cafes on Jeonju city in Korea. As a result of investigating work related pain, 65.3% (n=64) answered "yes" to the question that had pain at least once a week, month, or year, or 34.7% (n=34) answered "no". Most of the workers were right-handed, and when they felt pain, they felt 25 to 50% of time per day. Especially, baristas reported that the use of porter filters during work and the tamping operation were the most painful. In conclusion, our study indicated that necessary to introduce and develop a program to prevent cafe worker disease, as well as need to future research to improve work environment and posture according to the characteristics of the cafe works.

The purpose of this study was to examine the effect of a Interhemispheric Transfer exercise program on performance-related physical fitness factors of 18 elite high school fencers aged 17 to 19 years old. Participants were randomly assigned into 2 groups (EG, n=9), Cerebral Interhemispheric Transfer exercise program, and Control Group(CG, n=9) after considering gender ratio. Exercise intervention was performed 3 times a week for 4 weeks, and before and after the intervention, grip strength, back muscle strength, agility, reaction time, and flexibility were measured. The results and conclusions of this study are as follows. The interaction was found in the dominant grip strength (p<.05), but there was no significant interaction in the non-dominant grip strength. Agility was interactive (p<.01) and sig- nificantly increased in the control group (p<.01). Reaction time was significantly increased in both groups in the upper body reaction per- formance (p<.01). and there was also interaction between groups (p<.05). The number of dominant side foot step was significantly in- creased in both groups(p<.05, p<.01). but, In the number of non-dominant side increased significantly after intervention only in the control group (p<.01). Flexibility was increased significantly in both groups(p<.05, p<.01). The Interhemispheric Transfer exercise program had a positive effect on the strength, reaction time, and flexibility of the fencers, but there was no significant difference in agility. In the fu- ture, it is judged that additional research is needed to improve the performance of elite fencers through research on long-term non-dom- inant hand training programs.

Positive, negative, and nil effects of connectives in written stories: Analysis by proficiency groups

김하은,구성진,배정옥 경희대학교 언어정보연구소 2015 언어연구 Vol.32 No.S

Inconsistent findings about the significance of connectives in prior studies may be due to the fact that connectives were not analyzed according to their different semantic types as well as language users’ proficiency levels. The present study therefore divided connectives into four semantic types (additive, adversative, causal, and temporal) and examined how much their occurrences were related to the quality of free writing and whether the results varied because of proficiency levels. The participants were groups of different English writing proficiency (N = 242): Korean EFL elementary school immersion students and native English speakers who were middle or high school students attending an army-based American school. They were given a writing task which required them to create a story based on a picture. The stories were analyzed for connective occurrences and writing qualities such as content, text length, and vocabulary. The results show the following. As students become more proficient, the overall occurrences of connectives decreased. Additive and temporal connectives were most prevalent. However, their effects on writing qualities were different. In the stories by EFL students, the frequent occurrences of additive connectives negatively influenced the quality of content, while temporal connectives enhanced it. Such effects did not exist in the stories by native speakers; none of the connective types made any significant influence on the quality of content, indicating that with or without connectives content is comprehensible in the writings of proficient writers.
