Park, Charny,Yoon, Kyong‐,Ah,Kim, Jihyun,Park, In Hae,Park, Soo Jin,Kim, Min Kyeong,Jang, Wooyeong,Cho, Soo Young,Park, Boyoung,Kong, Sun‐,Young,Lee, Eun Sook John Wiley and Sons Inc. 2019 Cancer Science Vol.110 No.5

<P>Very young breast cancer patients are more common in Asian countries than Western countries and are thought to have worse prognosis than older patients. The aim of the current study was to identify molecular characteristics of young patients with estrogen receptor (ER)‐positive breast cancer by analyzing mutations and copy number variants (CNV), and by applying expression profiling. The whole exome and transcriptome of 47 Korean young breast cancer (KYBR) patients (age <35) were analyzed. Genomic profiles were constructed using mutations, CNV and differential gene expression from sequencing data. Pathway analyses were also performed using gene sets to identify biological processes. Our data were compared with young ER+ breast cancer patients in The Cancer Genome Atlas (TCGA) dataset. <I>TP53</I>,<I>PIK3CA</I> and <I>GATA3</I> were highly recurrent somatic mutation genes. APOBEC‐associated mutation signature was more frequent in KYBR compared with young TCGA patients. Integrative profiling was used to classify our patients into 3 subgroups based on molecular characteristics. Group A showed luminal A‐like subtype and IGF1R signal dysregulation. Luminal B patients were classified into groups B and C, which showed chromosomal instability and enrichment for APOBEC3A/B deletions, respectively. Group B was characterized by 11q13 (CCND1) amplification and activation of the ubiquitin‐mediated proteolysis pathway. Group C showed 17q12 (ERBB2) amplification and lower ER and progesterone receptor expression. Group C was also distinguished by immune activation and lower epithelial‐mesenchyme transition (EMT) degree compared with group B. This study showed that integrative genomic profiling could classify very young patients with breast cancer into molecular subgroups that are potentially linked to different clinical characteristics.</P>

Park, Minwoo,Im, Jungkyun,Shin, Minkwan,Min, Yuho,Park, Jaeyoon,Cho, Heesook,Park, Soojin,Shim, Mun-Bo,Jeon, Sanghun,Chung, Dae-Young,Bae, Jihyun,Park, Jongjin,Jeong, Unyong,Kim, Kinam Nature Pub. Group 2012 Nature nanotechnology Vol.7 No.12

<P>Conductive electrodes and electric circuits that can remain active and electrically stable under large mechanical deformations are highly desirable for applications such as flexible displays, field-effect transistors, energy-related devices, smart clothing and actuators. However, high conductivity and stretchability seem to be mutually exclusive parameters. The most promising solution to this problem has been to use one-dimensional nanostructures such as carbon nanotubes and metal nanowires coated on a stretchable fabric, metal stripes with a wavy geometry, composite elastomers embedding conductive fillers and interpenetrating networks of a liquid metal and rubber. At present, the conductivity values at large strains remain too low to satisfy requirements for practical applications. Moreover, the ability to make arbitrary patterns over large areas is also desirable. Here, we introduce a conductive composite mat of silver nanoparticles and rubber fibres that allows the formation of highly stretchable circuits through a fabrication process that is compatible with any substrate and scalable for large-area applications. A silver nanoparticle precursor is absorbed in electrospun poly (styrene-block-butadiene-block-styrene) (SBS) rubber fibres and then converted into silver nanoparticles directly in the fibre mat. Percolation of the silver nanoparticles inside the fibres leads to a high bulk conductivity, which is preserved at large deformations (σ???2,200?S?cm(-1) at 100% strain for a 150-?m-thick mat). We design electric circuits directly on the electrospun fibre mat by nozzle printing, inkjet printing and spray printing of the precursor solution and fabricate a highly stretchable antenna, a strain sensor and a highly stretchable light-emitting diode as examples of applications.</P>

JeongIl Yu,HeeChul Park,DooHo Choi,JaeMyoung Noh,Dongryul Oh,JunSu Park,JiHyun Chang,SeungTae Kim,Jeeyun Lee,SeHoon Park,JoonOh Park,YoungSuk Park,HoYeong Lim,WonKi Kang 대한방사선종양학회 2016 Radiation Oncology Journal Vol.34 No.1

Purpose: A prospective phase II trial was conducted to evaluate the effectiveness and toxicity of regional hyperthermia and whole liver irradiation (WLI) for numerous chemorefractory liver metastases from colorectal cancer. Materials and Methods: Enrolled patients had numerous chemorefractory hepatic metastases from colorectal cancer. Five sessions of hyperthermia and seven fractions of 3-gray WLI were planned. Health-related quality of life (HRQoL) was determined using the Korean version of the European Organization for Research and Treatment of Cancer quality of life questionnaire C-30 and the Functional Assessment of Cancer Therapy-Hepatobiliary version 4.0. Objective and pain response was evaluated. Results: A total of 12 patients consented to the study and the 10 who received WLI and hyperthermia were analyzed. WLI was completed as planned in nine patients and hyperthermia in eight. Pain response was partial in four patients and stable in four. Partial objective response was achieved in three patients (30.0%) and stable disease was seen in four patients at the 1-month follow-up. One patient died 1 month after treatment because of respiratory failure related to pleural metastasis progression. Other grade III or higher toxicities were detected in three patients; however, all severe toxicities were related to disease progression rather than treatment. No significant difference in HRQoL was noted at the time of assessment for patients who were available for questionnaires. Conclusion: Combined WLI and hyperthermia were well tolerated without severe treatment-related toxicity with a promising response from numerous chemorefractory hepatic metastases from colorectal cancer.

Jihyun Park,Hongjik Lee 대한스트레스학회 2011 스트레스硏究 Vol.19 No.4

본 연구는 중ㆍ장년의 삶의 만족도에 영향을 미치는 요인을 이들이 참여하는 자원봉사활동을 중심으로 탐색하였다. 본 연구는 수도권에 거주하는 만 45세 이상 자원봉사활동 참여자 274명을 대상으로 하였다. 분석결과, 자원봉사에서 할당된 활동, 개인적 효율성, 자원봉사 센터의 지지, 집단간 조화, 역할만족도는 삶의 만족도와 통계적으로 유의한 상관관계를 나타났으며, 회귀모형에서는 자원봉사에서 할당된 활동, 개인적 효율성이 통계학적으로 유의하게 이들의 삶의 만족도 수준을 결정짓는 요인으로 나타났다. 또한, 인구사회학적 특성을 동시에 고려한 통합회귀모형에서도 역시 자원봉사에서 할당된 활동과 개인적 효율성은 여전히 통계학적으로 유의하게 삶의 만족도에 영향을 미치는 것으로 나타났다. 본 연구는 이러한 연구결과를 토대로 중ㆍ장년층의 삶의 만족도를 증진시키기 위한 자원봉사운영에의 함의를 전달하였다. This study aimed to explore the factors that affect on their positive psychological well-being among older adults. Especially, it tried to examine how their volunteering work experiences affect their level of psychological well-being. The data of the Volunteerism among Older Adults between U.S. and South Korea by the Center for Excellence in Aging Services and Community Wellness (CEASCW) in 2010 were used for this purpose. 274 older volunteers in South Korea were adopted as the data of this study. This study conducted the descriptive analyses, correlation analysis and multiple regression analyses to explore the determinants of their psychological well-being. In the regression model, by adding socioeconomic characteristics, two antecedent factors-work assignment and personal efficacy were statistically significant. This result suggests that older volunteers with higher level of work assignment achieved and satisfaction with personal efficacy are more likely to present the higher status of well-being in later life. Therefore, volunteer agency should be took for older volunteers to consider the determinants of satisfaction in order to increase the retention rate of volunteering and improve psychological well-being in later life.

Macronutrients modified dietary intervention in the management of overweight/obese children and adolescents: a systematic review

Jihyun Park,Kim Oh-Yoen 대한소아청소년과학회 2024 Clinical and Experimental Pediatrics (CEP) Vol.67 No.4

The prevalence of obesity in adults and children is rapidly increasing worldwide. Obesity is among the main causes of chronic diseases and various problems, including economic consequences and they can also be affected by genetic, environmental, psychological, and socioeconomic factors. Dietary modification is a well-known and important factor in weight control, in particular, dietary macronutrient composition, food selection, dietary patterns, and energy restriction can affect weight reduction. Therefore, this systematic review aims to provide basic evidence for identifying the optimal macronutrient composition for managing obesity in Korean children and adolescents. We searched literature through an international database, studies were selected using our eligibility criteria and quality was assessedviaa risk of bias tool. In our results, several studieshave demonstrated that dietary macronutrient modifications affect body composition and metabolic markers in childrenand adolescents. In contrast, hypocaloric diets, regardless of macronutrient composition, are reportedly effective for weight loss in obese children. However, these findingswere based on intervention studies that examined the association between dietary macronutrient composition and obesity in non-Korean children and adolescents. Therefore, in the future, more intervention studies are needed to elucidate this relationship and evidence between macronutrients and obesity in Korean children and adolescents

Relationship between early development of plant community and environmental condition in abandoned paddy terraces at mountainous valleys in Korea

Park, Jihyun,Hong, Mun-Gi,Kim, Jae Geun The Ecological Society of Korea 2013 Journal of Ecology and Environment Vol.36 No.2

In Korea, many paddy fields in mountainous area have been abandoned because of their low accessibility and rice price and the abandoned paddy terraces have changed into natural lentic wetlands. To understand the relationship between characteristics of environmental conditions and early development of plant community in abandoned paddy terraces, we investigated at four well-maintained abandoned paddy terraces in 3 different climatic zones in Korea. Soil texture of abandoned paddy terraces was mostly kinds of loam and electric conductivity of soil was also similar among abandoned paddy terraces. On the other hand, contents of nitrogen, phosphorus, potassium, sodium, magnesium, and calcium in soil were relatively low and significantly different among abandoned paddy terraces. Water depth was different within sites and inter-sites. Although environmental conditions including climate, soil condition and water depth were different among abandoned paddy terraces, the compositions of plant communities were relatively similar in all abandoned paddy terraces. 55 dominant taxa out of 141 recorded species were commonly recorded over sites and they were mostly perennial obligate wetland plants and facultative wetland plants. 8 taxa out of 55 dominant taxa occurred at all abandoned paddy terraces with over 10% coverage. Several site-specific species occurred at site, which have some area with deep water level. This result indicates that early development of plant community in abandoned paddy terraces of similar water regime is similar in the entire area of Korea even though environmental conditions such as climate, biogeographic history and soil are different.
