Purpose Plasma neutrophil gelatinase-associated lipocalin (NGAL) is released from activated human neutrophil granules. Its concentration raises in many acute inflammatory state such as chronic obstructive pulmonary disease-acute exacerbation, low respiratory tract infection and acute kidney injury. But, the usefulness of plasma NGAL concentration for predicting the outcome of severe acute respiratory failure is unknown. In this study, we evaluated plasma NGAL as a potential prognostic biomarker in patients with severe acute respiratory failure. Method We prospectively collected blood samples from acute respiratory failure patients admitted to the intensive care unit (ICU) between March 2016 and June 2020. Plasma NGAL and inflammatory markers such as TNF-α, IL-1β levels of patients were measured on days 1, 3, 7 of hospitalization. We retrospectively reviewed patient medical records and analyzed correlations between the plasma NGAL concentration and hospital outcomes. Result A total of 46 severe acute respiratory failure patients were included in this study; 32 (69.6%) patients are survivors and 14 (30.4%) patients are non-survivors. In the survivor group, the concentration of plasma NGAL on days 7 of hospitalization decreased compared to the day 1 plasma NGAL concentration (p=0.002), but there was no significant decrease in the non-survivor group (p=0.794). The day 7 plasma NGAL concentration was associated with hospital mortality (p=0.042). Conclusion Acute respiratory failure patients with high plasma NGAL levels on days 7 of hospitalization have a high mortality rate. Therefore, plasma NGAL is useful for predicting outcomes of severe acute respiratory failure.

Background: With the introduction of Xpert MTB/RIF assay (Xpert), its incorporation into tuberculosis (TB) diagnosticalgorithm has become an important issue. The aim of this study was to evaluate the performance of the Xpert assay incomparison with a commercial polymerase chain reaction (PCR) assay. Methods: Medical records of patients having results of both Xpert and AdvanSure TB/NTM real-time PCR (AdvanSure)assays using the same bronchial washing specimens were retrospectively reviewed. Results: Of the 1,297 patients included in this study, 205 (15.8%) were diagnosed with pulmonary TB. Usingmycobacterial culture as the reference method, sensitivity of the Xpert assay using smear-positive specimens was 97.5%,which was comparable to that of the AdvanSure assay (96.3%, p=0.193). However, the sensitivity of the Xpert assay usingsmear-negative specimens was 70.6%, which was significantly higher than that of the AdvanSure assay (52.9%, p=0.018). Usng phenotypic drug susceptibility testing as the reference method, sensitivity and specificity for detecting rifampicinresistance were 100% and 99.1%, respectively. Moreover, a median turnaround time of the Xpert assay was 1 day, whichwas significantly shorter than 3 days of the AdvanSure assay (p<0.001). Conclusion: In comparison with the AdvanSure assay, the Xpert assay had a higher sensitivity using smear-negativespecimens, a shorter turnaround time, and could reliably predict rifampin resistance. Therefore, the Xpert assay might bepreferentially recommended over TB-PCR in Korean TB diagnostic algorithm.

Non-small cell lung cancer (NSCLC) remains the leading cause of cancer related death and 5-year survival rate is approximately 10-15%. Platinum-based chemotherapy has been demonstrated to improve survival in advanced NSCLC. Platinum-based paclitaxel and gemcitabine combination therapy considered moderately active regimen in patients with advanced NSCLC and warrants comparison with existing Platinum-based regimen in randomized trial. The aim of this study was to evaluate toxicity and efficacy of Platinum-based paclitaxel and gemcitabine combination therapy. The medical charts of fifty-six patients with NSCLC, who met selection criteria from January 2000 to March 2001, were reviewed retrospectively. They received one of three regimens greater than 2 cycles up to 7 cycles; paclitaxel (140㎎/㎡) and cisplatin (60㎎/㎡), paclitaxel (120㎎/㎡) and carboplatin (300㎎/㎡), gemcitabine (1000㎎/㎡) and cisplatin (60㎎/㎡). Data collection and analysis included baseline characteristics, hematologic and non-hematologic toxicity profiles according to WHO toxicity criteria and overall response according to clinician's opinion on basis of clinical results. As results, WHO grade above 2 hematologic toxicity occurred high in gemcitabine/cisplatin arm (9.6%) compared with other two arms (paclitaxel/cisplatin 2.8% vs. paclitaxel/carboplatin 5.8%). WHO grade above 2 non-hematologic GI toxicity occurred high in paclitaxel/carboplatin arm (5.2%) compared with other two arms(paclitaxel/cisplatin 3.4% vs. gemcitabine/cisplatin 2.5%). WHO grade above 2 non-hematologic excluding GI toxicity occurred high in paclitaxel/cisplatin arm(8.8%) compared with other two arms(paclitaxel/carboplatin 7.9% vs. gemcitabine/cisplatin 2.6%). Common side effects included nausea/vomiting, peripheral neuropathy and alopecia. Comparing toxicity profiles for the three regimens revealed no significant difference. Overall response rate was 22% for paclitaxel/cisplatin arm, 31% for paclitaxel/carboplatin arm, and 15% for gemcitabine/cisplatin arm. Comparing response rate for the three arms revealed no significant difference. The median survival period was 12.2 months for paclitaxel/cisplatin arm, 18.3 months for paclitaxel/carboplatin arm, and 8.3 months for gemcitabine/cisplatin arm. Comparing survival for the three arms revealed no significant difference. There were several limitations of this study, uncontrolled baseline disease, baseline toxicity, number of patient and number of effective cycles for the treatment group. Further well-designed study is required and pharmacist's role in ADR monitoring should be emphasized.

Pregnancy-associated plasma protein-A (PAPP-A) is known as an important biomarker for fetal abnormality during first trimester and has a pivotal role in follicle development and corpus luteum formation. And also, it is being revealed that an expression of PAPP-A in various cells and tissues such as cancer and lesion area. PAPP-A is the major IGF binding protein-4 (IGFBP-4) protease. Cleavage of IGFBP-4 results in loss of binding affinity for IGF, causing increased IGF bioavailability for proliferation, survival, and migration. Additionally, PAPP-A can be used as a promising therapeutic target for healthy longevity. Despite growing interest, almost nothing is known about how PAPP-A expression is regulated in any tissue. This review will focus on what is currently known about the zinc metalloproteinase, PAPP-A, and its role in cells and tissues. PAPP-A is expressed in proliferating cells such as fetus in uterus, granulosa cells in follicle, dermis in wound, cancer cells, and Sertoli cells in testis. They have common characteristics of proliferation faster than normal cells with stimulating IGFs action and inhibiting IGFBPs. The PAPP-A functions and expression studies in livestock have not yet been conducted much. Further studies are needed to use PAPP-A as a marker for healthy longevity in animal science.

This study investigates the influence of policy-related factors on the intention to keep working among mothers with children under 12 years old, especially focusing on the differences between the mothers with preschool children and elementary school children. The study also considers the individual, family, job characteristics of mothers with children, in order to draw the specific impact of policy factors. Data was collected through e-mails from 500 working mothers living in urban area, and 489 interview data were finally utilized in analyses. The results of analyses show that the level of awareness on work-family balancing policy significantly influences on the intention to keep working among mothers with preschool children. On the contrary, there is no statistically significant policy-related factors influencing on the intention to keep working among mothers with elementary school children. Both studies and social polices excessively focused on the mothers with preschool children in terms of work-family balancing issues. Working mothers with elementary school children have not been spot-lighted as beneficiaries from social policy, even though elementary school children also should be cared by others after school. Effective social services assisting work-family balance among mothers with preschool children should be more developed.

Multiple scale modeling has been applied to predict defect shape change during the wire rod rolling process. The size difference between bloom and defect prevent using usual FEM approaches due to the enormous number of elements required to depict the defect. The newly developed multiple scale model can visualize defect shape changes during the multi stands rolling process. The defect positioned at the top and side of bloom are smoothed out but the one at the middle evolved as folding or remained as crack. This approach can be used for defect control with roll shape design and initial bloom shape.

아름다운 자연경관과 함께 높은 생태학적 가치로 인해 대내외적으로 높은 브랜드 가치를 인정받고 있는 제주도는 최근 들어 정착에 실패하고 다시 도심으로 돌아가는 이주민의 증가로 인해 지역경제발전에 상당한 타격을 입고 있다. 본 연구는 ‘뜨는’ 제주를 찾아온 이주민들이 지역사회에 적응하지 못하고 다시 제주를 ‘뜨는’ 원인을 심리, 사회, 문화 등의 통합적 차원에서 분석하고 타 지역과 차별화되는 제주 특유의 상황적 요인을 구체적으로 파악하고자 3차에 걸쳐 실시되었다. 1차 연구는 정성적연구방법(qualitative research)을 통해 이주민들이 직면하는 제주 적응상의 어려움을 크게 교육환경, 의료환경, 쇼핑·문화, 지역정서, 교통, 상업활동, 이주민정책 등의 7개 영역으로 구분하고 각 영역에서의 문제점을 체계적으로 정리하였다. 2차 정량적 연구(quantitative research)에서는 7개 영역 중 ‘교육환경’, ‘쇼핑ㆍ문화’, ‘지역정서’, ‘상업활동’, ‘이주민정책’ 등의 5개 영역에서 이주민과 토착민 간의 차이점과 이주민과 토착민 간의 사회적 거리감과 사회적 관계형성의 어려움을 검증하였다. 3차 연구는 1차 연구 및 2차 연구의 결과물에 다양한 참고문헌과 전문가 의견을 종합하여 ‘제주 이주민의 성공적 정착을 위한 문화융합 척도개발’의 주요 구성요소를 교육환경, 의료시설, 문화와 여가, 지역정서, 주거와 교통, 경제활동, 복지와 안전, 이주민 정책 등 8개 영역으로 구분하고 총 36개의 하위 구성요소를 도출하였다. 본 연구가 제주 이주민의 지역사회 정착을 위한 효과적인 이주민정책수립의 기초자료로서 유용하게 사용되기를 기대한다. Jeju Island has recently suffered considerable damage to regional economic development due to the increase in migrants who fail to settle down. The purpose of this study is to analyze the causes of migrants who came to Jeju and are leaving Jeju again from failing to adapt to the community, from psychological, social, and cultural perspectives. Tree stepwise research was conducted in order to grasp the specific situational factors of Jeju that are different from other regions. The first study is a qualitative research in which the difficulties of adaptation to Jeju that migrants face are largely divided into 7 problem areas: educational environment, medical environment, shopping and cultural environment, regional sentiments, transportation, commercial activities, and migrant policies. The second study is a quantitative study that finds significant differences in 5 of the 7 areas which include, educational environment , shopping · culture , regional sentiments , commercial activities , and migration policy between migrants and Jeju natives. Also, the social distance between them and the difficulties in forming social relationships are statistically confirmed. The third study synthesizes various references and expert opinions on the results of the first and second studies and identifies the main components of ‘developing cultural convergence index for successful settlement of Jeju migrants.’ The main components are divided into 8 areas and a total of 36 sub-components were derived. We hope that this study will be useful as a basic data for making effective migrant policies in the successful settlement in Jeju.

본 연구의 목적은 공업도시, 산업도시 울산이라는 세간의 인식을 극복하고, 울산의 지역성을 바탕으로 사운드스케이프 관리를 통해 도시경쟁력을 확보하는 효과적인 방법을 제시하고 자 진행되었다. 연구목적을 위해 심층면접을 통한 자료수집이 진행되었으며, 울산과 지리적 자연환경과 산업구조가 유사한 크로아티아의 자다르(Zadar)의 소리풍경 관리를 통한 새로운 문화중심의 도시 브랜드 전략을 비교 분석하였다. 연구결과, 울산은 바다가 인접한 지역에 있음에도 공업도시의 이미지 이외에 관광도시라는 연상 자체에는 부정적인 인식이 강한 것으로 나타났다. 그러나 비교를 위해 장소적 영향력을 제한하며 노출시킨 자다르의 바다는 심층면접자의 인구통계적 특성과 상관없이 모두 여유, 힐링, 친환경의 도시로 인식하는 것으로 나타났다. 단지 자다르의 인공적으로 조성된 사운드스케이프 요소 하나만으로 도시에 대한 이미지와 환경에 대한 지각 여부가 긍정적으로 나타난 결과에 주목할 필요가 있다. 관광지로 개발하기 위해 산업사회에서는 건축물이나 박물관 같은 물리적 유형자원이 강조되었지만, 오늘날과 같은 창조경제 사회에서 경쟁력을 확보하기 위해서는 이미지, 정체성, 서사 등의 무형자원의 역할의 중요성이 강조된다. 사운드스케이프를 통한 도시브랜드 전략은 제조업의 몰락과 경제위기의 그늘 속에 삭막해진 이미지로 경쟁력을 잃어가는 국내외 도시들에 새로운 성장 방법론으로 활용될 수 있을 것이다. The purpose of this study was to overcome the perception of Ulsan, an industrial city and to propose an effective way to secure urban competitiveness through soundscape management based on Ulsan s locality. For the purpose of research, data collection through in-depth interview was conducted and Zadar in Croatia with similar natural environment with Ulsan was analyzed. As a result of the study, we find Ulsan has a negative perception in the association of sightseeing city, even though it is located near the sea. However, the sea of ​Zadar, which exposed and limited its place-based influence, was recognized as a leisure, healing and eco-friendly city regardless of the demographic characteristics of the in-depth interviewer. It is important to see the fact that Zadar s artificially created soundscape element positively affects the image and environment of the city. Although tangible resources such as buildings and museums are emphasized in the industrial society to develop attractions, today, intangible resources such as city image, identity, story telling, are more important. The urban brand strategy through soundscapes can be utilized as a new growth strategy for cities that are losing their competitiveness due to the decline of the manufacturing industry and economic crisis.
