현상학 연구는 질적 연구방법 중에서도 현상의 이면을 밝혀 그 본질을 도출하는 방법론이다. 이런 본래 의 현상학적 연구의 취지를 살려 연구의 성격에 맞춰 현상의 본질을 드러낼 수 있는 다양한 현상학적 방법 론이 적용될 필요가 있다. 하지만 현상학적 방법론은 현실적으로 지오르지(Giorgi)와 반마넨(Van Manen) 의 방법론에 치우쳐 있는 실정이다. 이런 문제의식을 바탕으로 본 연구자는 청소년의 학교폭력 경험에 적용 한 현상학적 자기평가방법의 분석방법을 고찰했다. 이 방법론은 환원과정이 4단계로 구체적이어서 현상학 의 본래 취지인 본질에 도달하는데 적합하다고 생각한다. 구체적으로 학교폭력 피해학생의 심층인터뷰를 활용해 현상학적 자기평가방법의 환원과정을 이 연구에서 보여주었다. 이 현상학적 자기평가방법은 사회복 지학이나 사회학에서 다루는 현상의 본질을 파악하기에 적합한 연구방법이라 할 수 있다.

In this study, the biogeochemistry management (BGC-MAN) model was applied to North and South Korea pine and oak forest stands to evaluate the Net Primary Productivity (NPP), an indicator of forest ecosystem productivity. For meteorological information, historical records and East Asian climate scenario data of Shared Socioeconomic Pathways (SSPs) were used. For vegetation information, pine (Pinus densiflora) and oak (Quercus spp.) forest stands were selected at the Gwangneung and Seolmacheon in South Korea and Sariwon, Sohung, Haeju, Jongju, and Wonsan, which are known to have tree nurseries in North Korea. Among the biophysical information, we used the elevation model for topographic data such as longitude, altitude, and slope direction, and the global soil database for soil data. For management factors, we considered the destruction of forests in North and South Korea due to the Korean War in 1950 and the subsequent reforestation process. The overall mean value of simulated NPP from 1991 to 2100 was 5.17 Mg C ha-1, with a range of 3.30-8.19 Mg C ha-1. In addition, increased variability in climate scenarios resulted in variations in forest productivity, with a notable decline in the growth of pine forests. The applicability of the BGC-MAN model to the Korean Peninsula was examined at a time when the ecosystem process-based models were becoming increasingly important due to climate change. In this study, the data on the effects of climate change disturbances on forest ecosystems that was analyzed was limited; therefore, future modeling methods should be improved to simulate more precise ecosystem changes across the Korean Peninsula through processbased models.

PURPOSES : In this study, the resources and energy consumed to produce hot mix asphalt mixtures and hot mix reclaimed asphalt mixtures in asphalt concrete plants were estimated and the emissions from the detailed processes of the production process were evaluated based on TRACI(the tool for the reduction and assessment of chemical and other environmental impacts). METHODS : To estimate the energy consumption of the aggregate drying process, which consumes a significant amount of energy in the production process, an energy consumption calculation model based on the thermal equilibrium equation was used, and the energy consumed for material transportation, storage, and operation of other facilities was cited from the literature. RESULTS : For the system boundary conditions established and the inventory considered, the emissions to produce one ton of hot mix reclaimed asphalt mix are greater than the emissions to produce one ton of hot mix asphalt mix for a number of key impact categories. The process of producing hot mix reclaimed asphalt mixtures was evaluated to consume more resources and energy in the production of recycled aggregates and heating for drying than in the production of hot mix asphalt mixtures, but less resources and energy in the production of binders and natural virgin aggregates and the heating to heat these materials. CONCLUSIONS : The results of the emissions assessment using the life cycle inventory for the production of hot mix asphalt mixtures were generally similar to the results understood in the field and in much of the literatures, confirming the reliability of the methodology. However, in order to evaluate the dominance of specific processes or mixtures, it is believed that the construction of a wide range of inventory databases after inventory redesign is necessary for a specific and rigorous assessment.

In this study, we applied a model of process-oriented English assessments to primary school students during the COVID-19 pandemic and explored how they perceived it. A series of flexible process-oriented assessments were conducted in the first semester of 2022. A survey was administered to 190 fifth-grade students at the end of the semester. The data were analyzed both quantitatively and qualitatively. The respondents were classified into three categories according to their self-rated English levels. The results show that the students appreciated the assessments, and they highly valued the teacher’s feedback. Various opinions were presented on providing opportunities for re-testing, reporting results to parents, writing peer reviews in school records, and mental pressures. The process-oriented assessments were found to be conducive for the majority of the young English learners, although some students from the lower group seemed to have experienced a psychological burden. Based on the findings, suggestions are made for educators in the post-pandemic era.

Recently, the construction of tall buildings utilized by high strength-concrete in the whole world is tending to be on the rise. The application of high-rise structural system in buildings results in the excellent cut-down effect in construction materials due to section reduction. Therefore, in order to investigate the CO2 and resource reduction effect for the high-rise structural system, comparisons of GWP and ADP in embodied energy of structural materlais between 4 type of high-rise structural system have been performed. As a result, GWP emission increased in the order of steel structure outrigger system, RC shear wall system, and RC outrigger system. On the other hand, ADP emissions increased in the order of RC shear wall system, RC outrigger system, and steel structure outrigger system.

In this study, the PBL class was applied to a Vietnamese video class. 13 learners were divided into 3 groups, and it was examined whether all learners grew toward their learning goals, and if so, through what process they grew. When group 1 announces a task, groups 2 and 3 perform peer evaluation and submit a peer evaluation sheet. For this, group 1 categorized the contents of peer evaluation into reflecting, partially reflecting, revised, and not reflecting to prepare the presentation evaluation sheet. Further, they were required to write a reason why “not reflecting.” A reflection log was also submitted. As a result of the above, the assignments were immediately revised, supplemented, and developed every week through peer and instructor evaluation. Through this process, the instructor learned in detail what kind of reflection the presenter and team members were doing each week. In particular, learners achieved ‘up-leveling’ with the activeness of immediately accepting each other’s strengths while conducting peer evaluations on each other’s presentations. This shows that the weekly assignments are improved, while the competencies of both the presentation team and peers are developed at the same time.

소변검사 전 냉/해동 반복과 해동 과정에 따라 대표적인 임상 화학검사 측정값의 변화를 확인 함으로써 소변검사의 안정성과 품질 개선방안을 모색하고자 하였다. 조사 대상자는 모두 건강한 남성 10명이었으며 이들의 소변 검체를 이용하여 냉/해동 안정성(freeze and thaw stability) 실험을 진행하였다. Micro-albumin과 Amylase의 경우 시간이 경과 됨에 따라 37℃에서 는 통계적 유의성은 없었으나, 42℃와 60℃에서는 시간의 경과에 따른 결과가 통계적으로 유의한 변동 이 있었고, BUN, Creatinine, Uric acid와 Glucose에서는 통계적으로 유의한 변동이 있었다. Long term의 안정성 결과, 7일이 지난 후에는 Glucose의 변이는 증가하였고, 60℃에서는 Amylase가 감 소하는 양상을 보였다. Glucose와 Amylase의 경우 시간의 경과에 따른 결과가 통계적으로 유의한 변동 이 있었다. 신뢰성 있는 검사결과를 얻기 위해서는 소변 시료의 채취, 보관 및 저장 등을 비롯한 요검사 의 정확한 표준화가 필요하며 생체 물질별 안정성 확보를 위한 조건들의 체계적 연구가 필요하다.

The purpose of this study is to develop guidelines for a Hindi A0 level evaluation test with its standardized Hindi curriculum. The development of a Hindi A0 level evaluation test is a basic requirement for ensuring internal stability of school education, because languages that uses special or unique characters that are not based on Roman alphabets, such as Hindi, Thai, and Persian, require a separate learning process or curriculum as well as their evaluation tests. This is not only in line with the purpose of the ‘Act on the Promotion of Education of Critical Foreign Languages’ enacted on August 2, 2016, but also because it can promote the substantiality of education in other critical foreign languages including Hindi, which had been conducted without a standardized curriculum. In other words, this study explores the concept of the A0 level that is not included in the CEFR, as a first step toward the realization of the ‘Common Asian Framework of Reference for languages’, the letters and pronunciations of which require a lot of time to learn. To this end, a guideline of an evaluation test for Asian languages is also proposed.

본 연구의 목적은 지역아동센터 정의와 발전배경을 살펴보고, 지역아동센터의 변천사에서 태동기, 발전기, 성장기, 정착기를 알아봄으로 지역아동센터 역사를 알아보았다. 태동기 1990년 이전에는 종교단체, 시민단체의 민간차원에서 공부방으로 시작되었으며, 발전기 1990년~2003년에는 아동복지법의 개정으로 법적인 제도권으로 진입하는 시기이다. 성장기 2004~2008년 전국 지역아동센터 공부방협의회를 발족하였고, 2004년 1월 법제화가 실시되었으며 2008년 지역아동센터 시범평가 실시를 통해 지역아동센터 관리의 질 향상을 꾀하였다. 지역아동센터정착기 2009년~현재 제도권 진입 후 2009년~2011년 지역아동센터 평가도입을 실시하였으며 종사자 역량 강화 교육을 실시하였고, 시설정보시스템 의무 사용으로 아동복지 종합복지 시스템으로 전환했다. 2012~2014년도 지역아동센터 평가센터를 설치 후 3년 주기의 평가지표를 구축하였다. 평가2기는 2015~2017년으로 진입평가와 심화평가로 분리하여 평가위원의 교차평가를 실시하였다. 평가 3기는 2018~2020년으로 중앙평가 운영위원회를 도입하고, 평가지표에 시설운영자의 철학을 추가하고 등급을 부여 하여 pass, non-pass시설에 컨설팅을 의무화 하므로 운영비 차별화를 주었다. 따라서 시설에서 바라보는 평가 체계 개선점을 제시함으로 지역아동센터 평가의 요소를 제고하는데 의의가 있다.

디스플레이 기술이 다양한 상품으로 점차 발전함에 따라 소비자가 선호하는 디스플레이 유형을 선택할 수 있는 효과적이고 객관적인 비교 평가 방법이 필요하다. 그러나 객관적이고 주관적인 디스플레이 품질 평가 방법은 디스플레이가 상이한 특성을 가지므로 다양한 디스플레이에서 일반적으로 유사하지 않다. 이에, 본 논문은 상대적으로 특성이 서로 다른 디스플레이의 인지 화질 평가를 위해 분석 네트워크 프로세스 (ANP)를 사용하여 이들 디스플레이의 상대적 화질 을 평가할 수 있는 체계적인 시스템을 제안한다. 제안된 평가 방법의 검증은 4 개의 모바일 디스플레이를 사용하여 평가 되었고, 주관적 평가와 제안한 방법의 선호도가 일치함을 보였다.

PURPOSES : This study is aimed at development of a stochastic pavement deterioration forecasting model using National Highway Pavement Condition Index (NHPCI) to support infrastructure asset management. Using this model, the deterioration process regarding life expectancy, deterioration speed change, and reliability were estimated. METHODS: Eight years of Long-Term Pavement Performance (LTPP) data fused with traffic loads (Equivalent Single Axle Loads; ESAL) and structural capacity (Structural Number of Pavement; SNP) were used for the deterioration modeling. As an ideal stochastic model for asset management, Bayesian Markov multi-state exponential hazard model was introduced. RESULTS: The interval of NHPCI was empirically distributed from 8 to 2, and the estimation functions of individual condition indices (crack, rutting, and IRI) in conjunction with the NHPCI index were suggested. The derived deterioration curve shows that life expectancies for the preventive maintenance level was 8.34 years. The general life expectancy was 12.77 years and located in the statistical interval of 11.10-15.58 years at a 95.5% reliability level. CONCLUSIONS : This study originates and contributes to suggesting a simple way to develop a pavement deterioration model using the total condition index that considers road user satisfaction. A definition for level of service system and the corresponding life expectancies are useful for building long-term maintenance plan, especially in Life Cycle Cost Analysis (LCCA) work.

The concern on the greenhouse gas emissions is increasing globally. Especially, the greenhouse gas emission from fisheries is an important issue due to Cancun Agreements Mexico in 1992 and the Kyoto protocol in 2005. Furthermore, the Korean government has a plan to reduce the GHG emissions as 5.2% compared to the BAU in fisheries until 2020. However, the investigation on the GHG emissions from Korean fisheries has not been executed much. Therefore, the quantitative analysis of GHG emissions from Korean fishery industry is needed as the first step to find a relevant way to reduce GHG emissions from fisheries. The purpose of this research is to investigate which degree of GHG emitted from the major coastal fisheries such as coastal gillnet fishery, coastal dual purpose fishery, coastal pots fishery and coastal small scale stow net fishery. Here, we calculated the GHG emission from the fisheries using the LCA (Life Cycle Assessment) method. The system boundary and input parameters for each process level are defined for LCA analysis. The fuel use coefficients of the fisheries are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for the unit weight of fishes are also calculated with consideration to the different consuming areas. The results will be helpful to understand the circumstances of GHG emissions from Korean fisheries.

The purposes of this study were to investigate the influences of channel assessments on the usage of multi-channels by product types, and the differences in the usage of multi-channels among product types in buying decision making process for fashion products. Data were collected from 510 consumers in their 20s to 50s with purchasing experiences through multi-channel distribution system and living in Seoul and Kyunggi province; 491 were analyzed after deleting incomplete questionnaires. Factor analysis, multiple regression analysis and one-way ANOVA were used for statistical analysis by using SPSS 18.0. The results were as follows: 5 factors were extracted for channel assessment: utility, accuracy, risk, price benefit and sharing information. Price benefits, utility and sharing information for online channel tended to influence positively on the usage of online channel and online+offline channels. Accuracy and low perceived risk of offline influenced positively on offline and on+offline channel usages. The usage levels of on-line and off-line channels for cosmetics were significantly lower than the usage levels for clothes and accessories on information search, evaluation of alternatives, and purchase stages. Significant differences were also found in the usage levels of multi-channels (on+off-line) on information search and evaluation of alternatives stages. The usage levels of the multi-channels for clothes were the highest followed by those of accessories and cosmetics in order.
