The aims of the present study were to test the task-induced vocabulary learning involvement load hypothesis in Korean university context and investigate whether the tasks actually induce the expected different levels of involvement load. A total of 75 English majors in a local university were randomly assigned to three task conditions that involved different levels of involvement: answering true-false questions after reading a glossed text, completing a gapped text using exact words from a glossary, and completing a gapped text affixing words from a glossary. On completing the tasks, the students were asked to take two post vocabulary tests and complete a survey designed to measure the difference in the amount of “evaluation” occurring cognitively during the performance of the task. Despite the trend that higher involvement led to more vocabulary learning, the results of a one-way analysis of variance showed no statistically significant differences in vocabulary retention among the three groups. On the other hand, the results of survey indicated that the group with the lowest involvement load achieved significantly lower scores, suggesting that the three tasks tapped different levels of vocabulary learning involvement. The theoretical and pedagogical implications of the study are discussed.

The adverse impact of personal protective equipment on firefighters’ cognitive functioning

Juyeon Park 복식문화학회 2019 服飾文化硏究 Vol.27 No.1

Firefighters wear Personal Protective Equipment (PPE) for protection from environmental hazards. However, due to the layers of protective functions, the PPE inevitably adds excessive weight, bulkiness, and thermal stress to firefighters. This study investigated the adverse impact of wearing PPE as an occupational stressor on the firefighter’s cognitive functioning. Twenty-three firefighters who had been involved in firefighting at least for 1 year were recruited. The overall changing trend in the firefighter’s cognitive functioning (short-term memory, long-term memory, and inductive reasoning) was measured by the scores of three standardized cognitive tests at the baseline and the follow-up, after participating in a moderate-intensity physical activity, wearing a full ensemble of the PPE. The study findings evinced the negative impact of the PPE on the firefighter’s cognitive functioning, especially in short-term memory and inductive reasoning. No significant influence was found on the firefighter’s long-term memory. The results were consistent when the participant’s age and BMI were controlled. The outcomes of the present study will not only fill the gap in the literature, but also provide critical justification to stakeholders, including governments, policymakers, academic communities, and industry, for such efforts to improve human factors of the firefighter’s PPE by realizing the negative consequences of the added layers and protective functions on their occupational safety. Study limitations and future directions were also discussed.

In the name of immigrant mothers : Gendered mobilization of Korean-Chinese women in South Korea

Juyeon PARK Asian Center for Women's Studies : Ewha Womans Uni 2019 Asian Journal of Women's Studies(AJWS) Vol.25 No.4

Drawing on ethnographic data from the anti-deportation protest of the Seoul Korean-Chinese Church (SKCC) in 2013, I examine the impact of gender on the mobilization of Korean-Chinese immigrant women in South Korea. Despite legal, economic, and religious differences, these protesters have bonded greatly among themselves, largely because of their immigrant mother identity. As the leaders of their family migration projects, both Christians and non-believers have grown to feel a strong sense of kinship and acknowledge the efficacy of collective action. Emotional protest rituals and the political impact of the activist-clergy have prompted the mobilization and consequent politicization of these largely women demonstrators. Early social movement literature has overlooked the impact of gender identity on women’s collective action, while my study shows how gender intersects with diasporic identities, to enable the mobilization of immigrant women for the collective goal of justice. 이 논문은 2013년 여름 서울조선족교회(SKCC)에서 열린 위명여권 사용자 강제추방 반대집회에서 서로 다른 경제적, 법적 지위를 가진 조선족 여성들이 어떠한 과정을 통하여 연대를 형성하였는지를 분석한다. 한국 이민자 정치에서 큰 역할을 담당해 온 개신교 이주자 교회(들)이 단체행동에 필요한 시민역량 (civic skills)을 전파하며 집회가 성공하는 데에 필요한 외부적/구조적인 조건을 제공했다면, 내부적으로 집회참가 여성들의 연대와 결속을 강화한 것은 젠더화된 “이주자 어머니” 정체성이었다. 교회에 등록되어 장기간 종교활동을 해 온 여성들은 상대적으로 안정된 법적, 경제적 지위를 누리고 있었던 반면에, 새 신자들 혹은 방문자들은 불안한 고용상태 속에서 자신, 혹은 가족의 강제추방을 막기 위한 목적으로 집회에 참여하고 있었다. 이 같은 차이에도 불구, 두 그룹의 여성들은 집회 중 여러 차례 반복된 증언(testimonies)과 사담 (small talk)을 통해 한국 사회에서 일상화된 이주자 차별의 경험과, 가족 전체의 이주를 계획하고 실행하는 과정에서 느끼는 책임감과 자기효능감을 많은 부분 공유한다는 것을 깨닫게 되었다. 이와 같은 집회의 감정적인 효능은 집회 참여자들이 이주자 여성/어머니로서 동질감과 유대감을 느끼게 하였고, 더 나아가 이주자 정의(immigrant justice)를 위한 공동행동의 필요성을 절감하게 하였다. 이 연구는 젠더화된 디아스포라 정체성이 이주자 여성들의 정치적 동원(mobilization)을 어떻게 강화할 수 있는가를 분석함으로써 기존 사회운동 연구들이 상대적으로 간과해 왔던 정치적 공동행동의 젠더화된 양상을 부각시키고자 한다.

Relationship between dietary sodium, potassium, and calcium, anthropometric indexes, and blood pressure in young and middle aged Korean adults

Juyeon Park,Jung-Sug Lee,Jeongseon Kim 한국영양학회 2010 Nutrition Research and Practice Vol.4 No.2

Epidemiological evidence of the effects of dietary sodium, calcium, and potassium, and anthropometric indexes on blood pressure is still inconsistent. To investigate the relationship between dietary factors or anthropometric indexes and hypertension risk, we examined the association of systolic and diastolic blood pressure (SBP and DBP) with sodium, calcium, and potassium intakes and anthropometric indexes in 19~49-year-olds using data from Korean National Health and Nutrition Examination Survey (KNHANES) Ⅲ. Total of 2,761 young and middle aged adults (574 aged 19~29 years and 2,187 aged 30~49 years) were selected from KNHANES Ⅲ. General information, nutritional status, and anthropometric data were compared between two age groups (19~29 years old and 30~49 years old). The relevance of blood pressure and risk factors such as age, sex, body mass index (BMI), weight, waist circumference, and the intakes of sodium, potassium, and calcium was determined by multiple regression analysis. Multiple regression models showed that waist circumference, weight, and BMI were positively associated with SBP and DBP in both age groups. Sodium and potassium intakes were not associated with either SBP or DBP. Among 30~49-year-olds, calcium was inversely associated with both SBP and DBP (P = 0.012 and 0.010, respectively). Our findings suggest that encouraging calcium consumption and weight control may play an important role in the primary prevention and management of hypertension in early adulthood.

A comparison of food and nutrient intake between instant noodle consumers and non-instant noodle consumers in Korean adults

Juyeon Park,Jung-Sug Lee,Young Ai Jang,Hae Rang Chung,Jeongseon Kim 한국영양학회 2011 Nutrition Research and Practice Vol.5 No.5

Instant noodles are widely consumed in Asian countries. The Korean population consumed the largest quantity of instant noodles in the world in 2008. However, few studies have investigated the relationship between instant noodles and nutritional status in Koreans. The objective of this study was to examine the association between instant noodle consumption and food and nutrient intake in Korean adults. We used dietary data of 6,440 subjects aged 20 years and older who participated in the Korean National Health and Nutrition Examination Survey Ⅲ. The average age of the instant noodle consumers (INC) was 36.2 and that of the non-instant noodle consumers (non-INC) was 44.9; men consumed more instant noodles than women (P<0.001). With the exception of cereals and grain products, legumes, seaweeds, eggs, and milk and dairy products, INC consumed significantly fewer potatoes and starches, sugars, seeds and nuts, vegetables, mushrooms, fruits, seasonings, beverages, meats, fishes, and oils and fats compared with those in the non-INC group. The INC group showed significantly higher nutrient intake of energy, fat, sodium, thiamine, and riboflavin; however, the INC group showed a significantly lower intake of protein, calcium, phosphorus, iron, potassium, vitamin A, niacin, and vitamin C compared with those in the non-INC group. This study revealed that consuming instant noodles may lead to excessive intake of energy, fats, and sodium but may also cause increased intake of thiamine and riboflavin. Therefore, nutritional education helping adults to choose a balanced meal while consuming instant noodles should be implemented. Additionally, instant noodle manufacturers should consider nutritional aspects when developing new products.

Onion Flesh and Onion Peel Enhance Antioxidant Status in Aged Rats

PARK, Juyeon,Kim, Joohee,KIM, Mi Kyung Center for Academic Publications Japan 2007 JOURNAL OF NUTRITIONAL SCIENCE AND VITAMINOLOGY Vol.53 No.1

<P>This study was designed to investigate the effects of dietary onion flesh or onion peel on lipid peroxides and DNA damage in aged rats. Sprague Dawley male rats (<I>n</I>=40, 16 mo old) were blocked into five groups and raised for 3 mo with either an onion-free control diet or onion diets (<I>Allium cepa</I> L., intermediate-day variety) containing either 5% (w/w) powdered dried onion flesh, 5% (w/w) powdered dried onion peel or ethanol extracts of the two powdered forms of onion. Total antioxidant status (TAS) and levels of total polyphenols and quercetin were greatest in onion peel ethanol extract, followed by onion peel powder, onion flesh ethanol extract, and onion flesh powder. Plasma quercetin and isorhamnetin levels were markedly increased by onion peel powder and onion peel ethanol extract. Rats fed onion flesh powder or onion peel powder had a higher plasma TAS than rats fed the control diet. Onion peel powder reduced liver thiobarbituric reactive substances relative to those of the control diet in aged rats (<I>p</I><0.05). Brain 8-isoprostane levels were markedly decreased by all four onion diets and the decrease was significant for the onion flesh powder and onion peel powder diets (<I>p</I><0.05). There was no significant decrease in cellular DNA damage in the kidney or brain tissue among rats fed the four onion diets. Onion flesh or onion peel enhanced antioxidant status in aged rats and may be beneficial for the elderly as a means of lowering lipid peroxide levels.</P>
