The objective of this study were 1) to determine the stages of concern of HE teachers about the practical problem-based curriculum approach, as illustrated by the Ohio's Work and Family Life Curriculum (W&FLC); 2) to determine the relationships between home economics (HE) teacher's stages of concern about W&FLC and personal and professional characteristics of HE teachers; and 3) to determine aspects of interest about the practical problem-based curriculum approach, such as the Ohio W&FLC. Respondents in this study were 225 HE teachers. The data were collected during the in-service teacher training sessions after presentation about W&FLC. Concerns Based Adoption Model (CBAM) was modified to provide a conceptual framework for this study. Frequencies, SD, mean, mode, range were used to determine the stages of concern of HE teachers. To determine the relationships between stages of concerns and personal and professional characteristics of HE teachers, coefficient of Chi-Square contingency tables was used. Content analysis was used to determine aspects of interest about the practical problem-bsed curriculum approach, such as W&FLC. The median of the stages of HE teachers' concerns about W&FLC was Stage 1, Information Stage. About 60% of HE teachers were interested in learning more details about W&FLC. Chi-square revealed no statistically significant relationships between stages of concerns about W&FLC and characteristics of HE teachers. Content analysis was used to determine aspects of interest about W&FLC of HE teachers. Nine categories were found: content, teaching strategies, implementation of the curriculum, philosophical framework, how to adopt W&FLC, resource materials, students' outcomes, in-service teacher training, and HE teacher organization. The majority of HE teachers were interested in relationships with family and others, resource management, family relationships, personal development, communication skill, family life, creating a self-identity, life planning, roles of family members, homemaking management, child care, and parenting.

본 연구에서는 뽕잎(Morus alba)을 노루궁뎅이 버섯균사체(Hericium erinaceum)로 발효시킨 열수 추출물(MA-HE)의 항산화 활성을 확인하고자 하였다. MA-HE의 항산화 활성을 DPPH radical, ABTS radical 소거활성 측정을 통해 알아보았다. 그 결과 DPPH radical 소거활성은 $500{\mu}g/mL$ 농도에서 61.73%, ABTS radical 소거활성은 $250{\mu}g/mL$ 농도에서 97.39%로 나타났다. MA-HE은 DNA의 산화적 손상을 효과적으로 억제하였다. 또한 생체고분자물질인 사람의 혈청단백질의 산화적 손상을 억제하였다. 세포에 $H_2O_2$를 처리하였을 때 세포생존율에 비하여 발효물을 $100{\mu}g/mL$ 농도로 전 처리한 세포생존율은 8% 증가했으며, 발효물을 $50{\mu}g/mL$ 농도로 처리했을 경우 세포 내 활성산소의 축적이 유의적으로 감소되었다. 본 연구 결과는 MA-HE이 항산화 활성을 가지고 있으며 산화적 스트레스에 의해 야기되는 세포 독성에 대한 보호 작용도 뛰어난 것으로 사료되었다.

This paper suggests a different reading of James Joyce's "Araby" by offering the video game as a lens through which we can reimagine the story. Understanding the unnamed boy's journey to the Araby bazaar as a fetch quest, this paper focuses on the boy's failure to complete this quest. As soon as the boy promises Mangan's sister something from Araby, his fetch quest begins. In order to complete the quest, the boy must successfully perform three sub-quests: get money from his uncle as early as he can, get on the train for the Araby bazaar on time, and pass through the sixpenny entrance at the bazaar. However, because his uncle comes home late, the boy fails to get the money early, and that sets off the subsequent failures. The boy then takes the train late and arrives at the bazaar so late that he feels he must go through any entrance. So he walks through the adult entrance by mistake. As a result, he does not have enough money to buy a gift, failing the larger quest. But, regardless of this failure, the boy can try these quests as many as he wants until he finally succeeds in completing them. But no matter how the boy tries to accomplish these subquests, he is doomed to fail them because he cannot make his uncle come home early. The more he tries his quest, the more bitterly he realizes that he will ultimately fail. In this respect, the boy's "anguish and anger" should be understood as his epiphany: the re-playability of the game is possible, but all the replays lead to the same failure: losing the game. In this regard, reading Joyce's "Araby" is much like playing a video game.

본고는 이규보(李奎報)(1168~1241)의 강남 유람 이전 시를 중심으로 그의 내면의식의 양상에 대하여 살펴보고자 하였다. 이규보는 그를 둘러싼 세상의 편견 속에서 삶의 방식을 고민했다. 또한 고립된 자신의 모습을 사물과 경물에 대한 주의 깊은 관찰을 통하여 서정적으로 보여 주었고, 청정(淸靜)한 공간에서 세상과 거리를 두며 순일(純一)한 자신의 내면을 기르고자 하였다. 이규보는 강남을 유람한 뒤 "강남집(江南集)"을 찬(撰)하였으며, 강남 유람 이후에는 구관(求官)을 반복하며 한림원에 보직될 때까지 순탄한지 못한 삶을 살아간다. 여기에서 특이한 점은 이러한 불우한 삶 속에서도 강남 유람 이전 시기와 같이 현실에 대하여 노골적으로 자신의 불우한 감정을 드러내는 경우가 드물다는 점이다. 이것은 광인(狂人)을 자처했던 자신의 삶을 세상에 순응해가는 완곡한 방식으로 전환하려는 조짐이 있었기에 가능한 것이라고 보인다. 즉 이러한 면모가 삶의 전체적인 궤적 안에서 강남 유람 이전 시기가 갖는 의의라고 할 수 있겠다.

Objectives : Present study investigated hepatoprotective effect of Haegan-jeon extract (HE) and tried to elucidate molecular mechanism involved. According to molecular mechanism, present study optimized herbal composition of HE (op-HE) and compared in vitro and in vivo hepatoprotective effects of op-HE to HE. Methods : For in vitro experiments, HepG2 cells were exposed to arachidonic acid (AA, $10{\mu}M$) and iron ($5{\mu}M$) for inducing oxidative stress. Cell viability, GSH contents, $H_2O_2$ production, mitochondrial membrane potential, immunoblot and reporter gene assay were performed to investigate cytoprotective effects and responsible molecular mechanisms. For in vivo experiments, hepatoprotective effect of HE and op-HE were assessed on $CCl_4-induced$ liver injury mice model. Results : HE pretreatment prevented AA+iron-mediated hepatocytes apoptosis. In addition, AA+iron-induced mitochondrial dysfunction, $H_2O_2$ production, glutathione depletion were reduced by HE pretreatment. In addition, nuclear factor erythroid 2-related factor 2 (Nrf2) phosphorylation, antioxidant response element (ARE)-driven reporter gene activity, and antioxidant genes expression were increased by HE. Based on reporter gene and MTT assays, we found that op-HE consisting three medicinal herbs also significantly increased transactivation of Nrf2 and reduced the AA+iron-mediated cytotoxicity. Moreover, in $CCl_4-induced$ liver injury mice model, HE-op had an ability to ameliorate $CCl_4-mediated$ increases in serum alanine transferase and aspartate aminotransferase activity, hepatic degeneration, inflammatory cell infiltration, and collagen deposition. Hepatoprotective effects of op-HE were comparable to those of HE. Conclusions : Present study suggests that op-HE as well as HE exhibit hepatoprotective effect against oxidative stress-mediated liver injury via Nrf2 activation.

This study was to examine home economics (HE) teachers' and the 1st-grade students' needs perception toward the purposes of HE education in middle school which has been practced since 1995 for both male and female students. This study, attempted (1) to analyze needs priority among the educational purposes of HE subject in relation to three systems of actions; (2) to compare differences between HE teachers' and students' perception concerning the degree of importance and achievement of the educational purposes of HE subject: and (3) to examine what they conceive as the problems In the current HE education. The survey was conducted with the samples of 600 1st-grade middle school students and 101 middle school HE teachers during the period of February-March 1996. The questionnaire used in this study was a modified version which had already been developed along with the 6th HE curriculum. For data analyses, SAS program was utilized to get Means and to perform both discrepancy test and t-test. The findings of this study were summarized as follows: first, with respect to each group's perception of the importance of the purposes related to three systems of action, HE teachers emphasized the importance of the purposes related to emancipatory action, while students placed more emphasis on the purposes related to technical action. Second, in terms of the degree of achievement, students had more positive perception on the degree of achievement of the purposes related to technical action than HE teachers did. Both groups marked low level of recognition on the degree of achievement of the purposes related to emancipatory action. Third, with respect to needs priority, HE teachers placed the first priority on emancipatory action, the second on technical action, and the last on communicative action: in the case of students, the first priority was on technical action, the second on communicative action, and the last on emancipatory action. In addition, the analysis of the opinions on the 6th curriculum revealed that most respondents found it necessary to secure adequate amount of classes for HE education. Also they shared the recongnition that HE curriculum should be renovated into the one which would fully appreciate the purposes of HE education from the perspective of the practical concerns of action which are distinct from the functional and technical concerns of passive learning. The findings of this study can serve as basic data for establishing the new purposes of HE education which put more emphasis on the purposes related to emancipatory action: as well as for developing an enhanced curriculum and reinforcing the identity of HE education.

A purpose of this study is to understand Platonic View of Health in $\boxDr$Politeia$\boxUl$. Though Plato was not so much a doctor as a philosopher. he had health care of children at heart. He mapped out an ideal type of nation in $\ulcorner$Politeia$\lrcorner$. and he founded a Akademeia in order to realize his dreams. In his course of education. he put emphasis on the problem of health. He extended poetry education for mental health and physical education for physical health. He placed high value on mental health above physical health. and poetry education corresponds to our reading education of today. He perceived that reading had a considerable influence on mental health promotion. According to his assertion, life style, too. had something to do with health condition. To lead a simple. temperate life makes one' health promote, on the other hand, to lead a complicated, intemperate life makes one' health injure. Morever, he approved of a eugenic marriage and the law of jungle. If one is unable to take care of one' health oneself. he would rather die than live. We cannot accept this proposal by general consent. but we cannot be too careful of our health. We can draw out a philosophy of health from Platonic View of Health. For example. the importance of health education. the preference of mental health. the influence of reading education. and responsibility for self-care, etc. We need to establish a philosophy of health scientifically by lasting study of records.

액체 헬륨은 열역학적 성질이나 운반성질에서 특이한 현상을 나타내기 때문에 그 성질의 연구는 흥미있는 관심사였다. 특히 액체 헬륨의 점성도는 $^4He가 ^3He$ 의 경우와 매우 틀리고 $\lambda$점 이하에서 초유체성을 나타내는 등 일반 액체 점성과는 판이하게 다르다. 저자에 의해 제시된 Brake이론이라 불리는 점성이론을 헬륨에 적용하여 타당성 여부를 조사하였다. 파라미터 고체부피($V_s$)를 조정하므로 액체 $^3He, ^4He$ 와 함께 기체 및 dense gas를 동시에 적용하여 계산하였고, 그 계산 결과는 실험값과 잘 일치했다.

Anti-melanogenesis and skin anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Ganoderma applanatum were investigated in this study. The total phenolic contents of the ME and HE of the mushroom were 11.68 and 3.15 ㎍ GAEs/mg, respectively, whereas the total flavonoid contents of the ME and HE were 21.82 and 2.69 ㎍ QEs/mg, respectively. The survival rate of B16-F10 murine melanoma cells treated with 750 ㎍ ME and HE were 83.46% and 85.54%, respectively, thereby suggesting that mushroom extracts were slightly cytotoxic at the tested concentration. The in vitro tyrosinase inhibition by ME (83.15%) and HE (83.44%) was significantly lower than that of kojic acid (99.61%), the positive control, at 2.0 mg/mL. Although the inhibition of cellular melanin synthesis in B16-F10 melanoma cells by 2.0 mg/mL of ME (50.24%) and HE (51.24%) was lower than that of arbutin (64.84%), the inhibition by both ME and HE was higher than 50%. Collagenase inhibition by HE was comparable to 2.0 mg/mL epigallocatechin (EGCG), the positive control; however, elastase inhibition by ME and HE was lower than that of EGCG at the concentration tested. The results showed that the fruiting bodies of G. applanatum had good anti-tyrosinase, good anti-collagenase, and moderate anti-elastase activities, which might be useful for developing novel skin-whitening and anti-wrinkle agents.

Human error (HE) is an important concern in safety-critical systems such as nuclear power plants (NPPs). HE has played a role in many accidents and outage incidents in NPPs. Despite the increased automation in NPPs, HE remains unavoidable. Hence, the need for HE detection is as important as HE prevention efforts. In NPPs, HE is rather rare. Hence, anomaly detection, a widely used machine learning technique for detecting rare anomalous instances, can be repurposed to detect potential HE. In this study, we develop an unsupervised anomaly detection technique based on generative adversarial networks (GANs) to detect anomalies in manually collected surveillance data in NPPs. More specifically, our GAN is trained to detect mismatches between automatically recorded sensor data and manually collected surveillance data, and hence, identify anomalous instances that can be attributed to HE. We test our GAN on both a real-world dataset and an external dataset obtained from a testbed, and we benchmark our results against state-of-the-art unsupervised anomaly detection algorithms, including one-class support vector machine and isolation forest. Our results show that the proposed GAN provides improved anomaly detection performance. Our study is promising for the future development of artificial intelligence based HE detection systems.
