영구치의 외상성 손상은 전체 외상 환자 중 높은 빈도로 발생하며 사고의 대부분은 치근이 미완성되어 있는 시기에 발생하 여 치수, 치주인대, 치조골, Hertwig 상피 근초(HERS)에 다양한 영향을 주게 된다. 손상 정도에 따라 치수의 완전한 재혈관 화, 근관 석회화, 근관내 치조골 함입 등의 다양한 치유 양상을 나타내며, 치근단의 성장 정지 및 치수 괴사로 인한 염증성 치 근 흡수 등의 합병증을 나타낼 수 있다. 본 증례에서는 미성숙 영구치 치근단을 가진 세 환아에서 외상에 의한 Hertwig 상피 근초의 손상으로 발치와 기저부에 존 재하는 치근막 세포와 골세포의 치수강내로의 증식으로 인해 치근 발육 정지 및 근관내로의 치조골 함입을 나타내어 보고하 고자 한다. 외상 후 Hertwig 상피 근초의 손상에 의한 근관내로의 치조골 함입 치유 양상은 치수는 정상적인 기능을 하는 것으로 생각 되며, 유착 등의 합병증이 동반되지 않는 경우 특별한 치료를 필요로 하지 않으므로 감별 진단이 요구되며, 외상 받은 치아의 치료시 Hertwig 상피 근초에 대한 부가적인 외상을 가하지 않도록 주의해야 한다. Traumatic injury on tooth occurs frequently among trauma patients, and mainly occurs on tooth with premature roots which influences pulp tissue, periodontal ligament, alveolar bone, and Hertwig’s epithelial root sheath. According to the degree of trauma, a number of kinds of healing process can be observed, such as complete re-vascularization of pulp, root canal obliteration, growth suspension of root apex, and invasion of alveolar bone into root canal, and there can be some complications such as necrotic change of inflammatory root resorption and partial pulp necrosis due to pulp necrosis toward complete necrosis. In this clinical case, 3 patients who had traumatic injury showed root growth suspension and alveolar bone invasion into root canal due to proliferation of periodontal ligament cell and osteocyte at the base of extraction socket into pulp chamber because of the injury on Hertwig’s epithelial root sheath. If intrusion of alveolar bone into root canal due to injury on Hertwig’s epithelial root sheath after having traumatic injury doesn’t show any complication, the pulp may be considered to have normal vitality and doesn’t need any further treatment, therefore differential diagnosis is very necessary. However, it may be accompanied with suspension of root growth, therefore, additional trauma during the treatment of injured tooth should not be applied.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

In addition to the development of functional cosmetics, technology to increase percutaneous absorption rate when applied to the skin is an important task. In this experiment, oleic acid was used as a skin absorption promoter, and its effect on transdermal permeability of adenosine was studied and analyzed using a skin-like membrane. As a result of the experiment, it was investigated that the permeability coefficient and concentration of adenosine are proportional to the content of oleic acid. This indicates that a high proportion of oleic acid is effective as a skin absorption promoter.

Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (DPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of CDPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

The study analyzed the physical and chemical properties of dry-torrefied (DT) and wet-torrefied (WT) biomass. Hemicellulose was mainly degraded by torrefaction, and the contents of glucan and lignin were relatively increased. The degradation rate of biomass was higher in WT (18.25%–23.13%) than in DT biomass (3.12%–3.83%), and it increased with increasing reaction time. Torrefaction improved the crystallinity of the biomass from 36.88% in the raw material to a maximum value of 60.97% in the biomass subjected to wet torrefaction for 30 min (WT-30). The thermal stability of torrefied biomass was improved in WT-10 (17.21%), WT-60 (15.38%), and DT-60 (8.74%) compared to that of the raw material (2.35%). The hydrophobicity and fine particle distribution of biomass were increa- sed by torrefaction, with the lowest water absorption (3.08%) and the highest distribution of fine particles (8.20%) being observed in WT-60 biomass.

Imaging plays a key role in the diagnosis and characterization of thyroid diseases, and the information provided by imaging studies is essential for management planning. A referral guideline for imaging studies may help physicians make reasonable decisions and minimize the number of unnecessary examinations. The Korean Society of Thyroid Radiology (KSThR) developed imaging guidelines for thyroid nodules and differentiated thyroid cancer using an adaptation process through a collaboration between the National Evidence-based Healthcare Collaborating Agency and the working group of KSThR, which is composed of radiologists specializing in thyroid imaging. When evidence is either insufficient or equivocal, expert opinion may supplement the available evidence for recommending imaging. Therefore, we suggest rating the appropriateness of imaging for specific clinical situations in this guideline.

In uterine sarcoma, leiomyosarcoma is the most common, with low grade endometrial stromal sarcoma and high grade endometrial stromal sarcoma. Among them, Rhabdomyosarcoma (RMS) is a very rare, aggressive mesenchymal tumor. Usually diagnosed in the pediatric period, it occurs commonly in the head and neck, urinary tract, reproductive organs, limbs and trunk. RMS is subclassified into embryonal, alveolar, anaplastic (previously called pleomorphic), and spindle cell / sclerosing variants. In adult patients, mostly, it occurs in soft tissues of limbs. RMS appears as a rhabdomyosarcomatous differentiation, usually with adenosarcoma, carcinosarcoma, and more rarely as a pure form of RMS. Clinicopathologic information is restricted compared with other gynecologic malignancies because the incidence is very rare. A 71-year-old patient visited the hospital to abdominal discomfort, anorexia and constipation. She was diagnosed as cervical cancer IIIB, squamous cell carcinoma in 2009, and underwent adjuvant concurrent chemoradiation therapy and chemotherapy of cisplatin and etoposide regimen. Followed by, Intracavitary radiotherapy (ICR) was performed with external beam radiation therapy (EBRT) 4,500cGy / 25fractions and parametrial booster 600cGy. The patient has been up until recently with no evidence of disease (NED). The patient underwent abdominopelvic CT and found a huge heterogeneous mass of 20 cm in size. The patient underwent surgery because of suspected recurrent cervical cancer or ovarian cancer. At the time of surgery, the tumor was suspected to be sarcoma rather than cervical cancer or ovarian cancer. However, before chemotherapy, she complained of speech disturbances and facial paralysis. She was referred to a neurologist and underwent brain MRI. Multiple masses on the occipital bone and parietal bone was detected and diagnosed as skull metastasis. PET / CT images were taken under the skull base level, so metastic diseases were not diagnosed preoperatively.
