스트레스는 매일 살아가면서 사소한 일부터 큰 충격을 받는 삶의 주요한 사건까지 다양한 요인으로부터 온다. 이는 어느 한 시기에만 나타나는 것이 아니라, 생애에 거쳐 나타나므로 지속적으로 스트레스를 관리할 수 있는 연구가 필요하다. 본 연구에서는 사용자 스스로 스트레스를 진단, 관리할 수 있는 홍채 분석기반 시스템을 개발하였다. 그리고 홍채진단에 의한 스트레스 지수와 설문기반의 스트레스 지수의 상관성을 분석한 후, 사용자의 스트레스 지수를 정량화하였다. 본 연구에서 제안하는 시스템은 사용자가 쉽게 현재 자신이 느끼고 있는 스트레스 정도를 알 수 있고, 이에 상응하여 예측되는 질병에 대한 조기 진단 및 질병예방의 하나의 방법으로 사용할 수 있을 것이다.

The cells that make up the body continuously undergo cell division to maintain life, but stress and carcinogens, and physiological stimuli suppress immunological functions in the body and change cells to cancerous cells. The only way to overcome cancer is by treatment through early detection and proper diagnosis. However, because early stage of cancer shows subjective symptoms that are similar to those of other common illnesses, even doctors have difficulty separating cancer from common illnesses in its early stage. However, the Ki(bioenergy) present in our body recognizes and changes to the most minute changes in the body. This method of detecting the change in bioenergy to discover a disease in the early stage to raise treatment success is called the OBET: O-Ring, Bioenergy Test. This method, which is based on the theories of oriental medicine, focuses on tumors, especially malignant tumors, and has shown value in diagnosis and treatment, as witnessed in the clinical applications. The diagnosis method and cases of OBET: O-Ring, Bioenergy Test are presented.

The main purpose of this methodological study was to develop an assessment tool and intervention protocol for child and family with childhood cancer at early diagnosis stage. The assessment tool and intervention protocol was developed by extensive literature review and consultation with experts. Review of nine domestic and sixty-six international journal articles were done to identify stress, interventions, coping strategies and adjustment of children with cancer and their family. Results were as follows; First, assessment at the early diagnosis stage need to include information on patient, family, and patient/family attitude toward diagnosis and treatment. Second, intervention protocol for children with cancer includes control physical symptoms, manage the side effects of chemotherapy and diagnostic or therapeutic procedures, control emotional responses, provide support and information, assist decision-making and adjust to environment. Third, intervention protocol for family includes controlling emotional responses, provision of informations, inducing family support to patient, improving family cohesion, supporting siblings and supporting spiritual growth. In conclusion, the early diagnosis stage in cancer treatment is important for child and family since this stage greatly affects the overall adjustment of child and family to live with cancer. Therefore, pediatric nurses need to be sensitive to the need of patient/family and systematically manage their needs at this stage.

Traumatic brain injury(TBI) used to be developed after a severe traumatic event. Therefore TBI usually induces acute or chronic stress reaction. I reviewed the concept, epidemiology, biological or psychosocial etiology, diagnosis and treatment of post-traumatic stress disorder (PTSD), and discussed about PTSD or stress reaction after TBI. Early evaluation and management of stress reaction after TBI are important.

Many concrete bridge decks develop transverse cracking shortly after construction. These cracks accelerate corrosion of reinforcing steel and lead to concrete deterioration, damage to components beneath the deck, unsightly appearance. These cracks shorten the service life and increase maintenance costs of bridge structures. In this study, VES-LMC overlay, which provides the same benefits as a conventional overlay, is designed to cure very quickly. Although the materials for VES overlays are more expensive, the cost is more than offset by the savings on traffic control and work zone safety measures. Otherwise, reaction of hydration occurs very rapidly in beginning step(concrete placing). As a results, thermal cracking can be occur by thermal stress in accordance with hydration-heat The purpose of this study was to estimate diagnosis of crack occurrence of VES-LMC through field tests at early-age.

Objective: Prompt diagnosis and management are essential for saving the adnexal organs from infarction in cases of ovarian torsion (OT). This study aimed to determine the diagnostic significance of signal peptide, complement C1r/C1s, Uegf, and Bmp1 (CUB), and epidermal growth factor-like domain-containing protein-1 (SCUBE-1) levels in cases of OT, an emergent ischemic condition, and the relationship of SCUBE-1 with oxidative stress parameters. Methods: This prospective study was conducted among 15 OT patients and 20 age- and gravidity-matched healthy women. SCUBE-1 serum concentrations were determined by using enzyme-linked immunosorbent assays. In addition, oxidative stress was evaluated by measuring the serum levels of advanced oxidation protein products (AOPP), ferric reducing ability of plasma (FRAP), and glutathione (GSH). Results: The SCUBE-1 titers were significantly higher in the patients with OT than in the controls (p=0.008). In addition, serum FRAP and GSH levels were significantly lower in the OT patients than in the controls (p<0.001 for both). Serum AOPP levels were higher in the OT patients, but this trend was not statistically significant (p>0.05). Furthermore, there were no correlations between SCUBE-1 levels and age, gravidity, parity, cyst size, and AOPP, FRAP, or GSH levels (p>0.05). Conclusion: We believe that SCUBE-1 may be a promising biomarker for the early diagnosis of OT.

Scince $^{201}$TI was introduced as a myocardial perfusion imaging agent in the early 1970s, scintigraphic evaluation of myocardial perfusion for the diagnosis of coronary artery disease is a valuable noninvasive diagnostic imaging modality. Stress radionuclide myocardial perfusion imaging is widely accepted to have high diagnostic and prognostic use in the assessment of patients with known or suspected coronary artery disease. With wise use of this nonivasive imaging technique, more patients are referred for stress perfusion imaging. Until now various protocols for stress testing and myocardial imaging were developed and used in worldwide. This article presented various protocols of stress testing and myocardial imaging for clinical use.

흡연, 당뇨, 비만 및 스트레스 등에 의한 심장 질환이 증가됨에 따라 이로 인한 사망률이 늘어나면서 심장 질환은 현대 사회에서 조기 진단의 필요성을 제시하고 있는 실정이다. 특히 심장 질환에 대한 사람들의 무지와 무관심 때문에 발병율이 급격히 증가하고 있다. 따라서 이와 같은 심장 질환에 대한 사회적 현상을 해결하기 위해 본 논문에서는 동의보감에서 제시하고 있는 심장 상태에 대한 진단 이론을 기반으로 심장 질환의 조기 진단에 필요한 객관적 출력 변수를 설계하였다. 특히 심장 질환에 따른 발음의 부정확성을 입증하기 위해 성대의 진동 변화율을 추출하여 실험 집단간의 비교, 분석을 수행하였다. 이를 위해 본 논문에서는 표준어를 구사하는 성인 남성 중에서 심장 질환을 앓고 있는 환자들과 심장에 이상이 없는 정상인들로 피실험자 집단을 구성하고 이들의 음성을 수집하여 성대 진동의 변화율에 대한 비교, 분석을 통해 심장 질환에 대한 조기 진단 방법을 제안하였다.

Because nonalcoholic steatohepatitis can progress towards cirrhosis even in children, early detection of hepatic fibrosis and accurate diagnosis of nonalcoholic fatty liver disease (NAFLD) are important. Although liver biopsy is regarded as the gold standard of diagnosis, its clinical application is somewhat limited in children due to its invasiveness. Noninvasive diagnostic methods, including imaging studies, biomarkers of inflammation, oxidative stress, hepatic apoptosis, hepatic fibrosis, and noninvasive hepatic fibrosis scores have recently been developed for diagnosing the spectrum of NAFLD, particularly the severity of hepatic fibrosis. Although data and validation are still lacking for these noninvasive modalities in the pediatric population, these methods may be applicable for pediatric NAFLD. Therefore, noninvasive imaging studies, biomarkers, and hepatic fibrosis scoring systems may be useful in the detection of hepatic steatosis and the prediction of hepatic fibrosis, even in children with NAFLD.

다양한 환경 스트레스 중 습해 스트레스의 경우 기타 가뭄이나 저온, 고염 등에 비하여 메커니즘과 생화학적 이해가 부족한 실정이다. 본 연구는 습해 스트레스 하에서의 밭작물의 효소활성에 대하여 조사하여 습해 스트레스에 대한 이해와 조기 진단을 위한 기초자료로 활용하고자 수행하였다. 국내의 주요 밭작물인 참깨, 들깨, 팥, 수수, 콩 등을 대상으로 침수 스트레스를 주었을 시 생육도와 식물 내부의 변화에 대하여 조사하였는데, 스트레스를 받을 경우 지하부는 물론 지상부에서도 생육의 저하가 일어나는 것을 확인하였다. 식물체 내에서는 침수 스트레스에 의하여 혐기적 발효가 일어나 대조군에 비하여 ADH의 활성이 높아지는 것을 확인하였으며 스트레스를 받을 시 발생하는 ROS에 의한 변화 또한 확인하였다. 습해를 받은 식물들 모두 POD 활성과 lipid peroxidation이 증가하였고 이를 시각화한 DAB 염색에서도 염색 강도가 대조군에 비하여 진하게 염색되었다. 지상부에서 표현형의 변화보다 식물 체내의 효소활성의 변화가 비교적 빠르게 나타나므로 추후 작물들의 습해 스트레스 조기진단을 위한 생체지표로써 활용될 수 있을 것으로 사료된다.
