2020년 1월, 「개인정보 보호법」, 「정보통신망 이용촉진 및 정보보호 등에 관한 법률」, 「신용정보의 이용 및 보호에 관한 법률」 의 개정안이 국회 본회의를 통과하였다. 현행 법률이 개인정보의 보호에 치우쳐 정보의 활용이 어렵고 감독 기구의 분산과 규정의 중복 등으로 수범자들이 혼란을 가중시켜 데이터 활용 경제 산업의 발전을 저해한다는 비판을 수용하여, 이번 개정법에서는 가명 정보를 활용하고 마이데이터 산업을 도입, 개인정보 보호위원회를 독립기구로 일원화 하는 등의 내용으로 많은 부분이 개정되어 4차 산업혁명의 시대를 본격화할 것이라는 기대를 모으고 있다. 하지만 가명 정보의 활용에 대한 프라이버시(Privacy)침해에 대한 우려와 함께 여전히 중복된 규정이 혼재하며, 모호한 개념이 존재, 가명정보의 활용이 실효성을 거둘 수 있을지 등의 비판과 우려의 목소리도 높다. 이에 본 논문에서는 데이터 3법의 개정 내용과 의미에 관하여 서술하고, 추후 과제를 세 가지 측면, 즉 프라이버시 침해 우려에 대한 개인정보자기결정권의 실질 보장을 위한 시스템 구축, 안전조치 확보를 위한 인증제도의 구축 및 합리적인 가이드라인의 지속적인 제시, 독립 기구로서의 개인정보보호위원회의 전문적 업무 수행의 기대에 대하여 개략적으로 제시한다.

Purpose: The purpose of this study was to analyse eating patterns and physical activities according to obesity of female middle school students in Korea. Methods: The 2010 Korea Youth Risk Behavior Survey (KYRBS) data was used for analysis. The subjects of this study were 11,996 female middle school students (10,118 normal weight and 1,778 overweight). The data were analyzed using descriptive analysis, independent t-test, and ${\chi}^2$-test. Results: The findings of this study Indicated that 52.1% of the normal weight group did efforts to lose weight, whereas 60.1% of the overweight groups did. The most common way of reducing body weight was 'reducing food intake', followed by 'regular exercise', 'taking diet supplements' and 'fasting'. Among the entire groups of respondents, 54.6% did not receive dietary education at school over the past year. In addition, 18.8% in normal weight group and 17.0% in overweight group had never receive physical education at school over the past year. Conclusion: The health provider should enhance the school based dietary education and physical education programs for the promotion of adolescents' health status and healthy behaviors.

PURPOSE : The Purpose of this study was to investigate the anti-inflammatory effect on combination dosage of dexamethasone and naproxen after removal of impacted 3rd molars. We evaluated postoperative pain, swelling, and mouth opening limitation quantitatively. PATIENTS AND METHODS : Removal of an impacted lower third molar was done under local anesthesia with 2% lidocaine to 239 healthy patients. We randomly gave experimental group 1.5mg dexamethasone and 200mg naproxen three times a day for postoperative 2days, and also gave control group 200mg naproxen alone three times a day for postoperative 2days. Swelling and pain were measured by visual analogue scale (VAS). Mouth opening limitation was measured by maximum interincisal opening length. We estimated these measurements in the first and second postoperative days. Differences between experimental and control group were investigated considering age, sex, BMI(body mass index), impacted type, surgical site(right or left), and operation time by independent student T-test. RESULTS : In general, swelling, pain, and mouth opening limitations were significantly reduced (p<0.01) by combination dose of dexamethasone and naproxen in postoperative one day. But there was no difference in pain on the second postoperative day. As variables being considered, in the postoperative pain, there was significant difference between experimental group and control group in only male, little bony removal group, left side extraction group. In case of postoperative swelling, there was no significant differences in male, adolescence, long operating time group (over 20 minutes), medium BMI group and right side extraction group. In case of postoperative mouth opening limitation, there was significant difference between only female and long operating time group (over 20 minutes). CONCLUSION : Variables being considered, postoperative swelling was more reduced by the combination dose of naproxen and dexamethasone than that of naproxen alone after removal of impacted 3rd molars. But there was varoius results in pain and mouth opening limitation.

This study compares the net effect of wearing different shoulder/arm armor systems on garment impediment perception and wearer acceptability. Two independent variables in this study were armor systems and shoulder/ arm movements. There were four armor systems of control garment and arm armor systems A, B, and C as well as five types of arm/shoulder movements, (shoulder flexion, should extension, shoulder abduction, shoulder horizontal flexion, and shoulder horizontal extension). Ten male volunteers wearing size medium battle dress uniform (BDU) with recent relevant military experience participated in this study. The volunteers performed shoulder/arm movements (while wearing each armor treatments) and completed the garment impediment perception as well as wearer acceptability scales. The body areas of neck side, shoulder top, and armscye front showed the highest frequency of reported impediments. Resistance to movement and localized pressure were the most frequently mentioned types of impediment. The armor system B had the most areas of impediment, and was rated as more restrictive than the control garment and armor system A for each movement. For wearer acceptability, no significant differences were found between the control garment and armor system A for all eight items; this indicated that subjects did not perceive a difference between wearing the control garment and armor system A. There was a trend for wearer acceptability to decrease from wearing the control garment to armor systems A to C to B.

Background: Forward head posture (FHP) is common postural malalignment. FHP is described relatively extension to upper cervical and lower cervical is relatively flexion. Although several researchers mentioned the lower cervical flexion posture in FHP, most of the studies related to FHP is focused on the deep cervical flexor function. Objects: The purposes of present study is to compare the cervical strength (upper cervical extension [UCE], lower cervical extension [LCE], upper cervical flexion [UCF], lower cervical flexion [LCF]) between individuals with and without FHP. Methods: Fifty-one participants are recruited. Participants who have the craniovertebral angle (CVA) less than 48 degree were classified to the FHP group (n = 24) and the others were included in without FHP group (n = 27). The cervical strength (UCE, LCE, UCF, LCF) were measured using Smart KEMA strength sensor and the strength data was normalized by body weight. All strength measurement conducted at head and neck neutral position in sitting. Independent t-test was used to compare the cervical strength between individuals with and without FHP. Results: The mean value of CVA was greater in without FHP group than with FHP group (p < 0.000). The strength value of UCF (p < 0.002) and LCE (p < 0.001) was significant less in FHP group than without FHP group. But no significant differences were seen in the LCF and UCE strength between two groups. Conclusion: UCF and LCE weakness in FHP group should be considered to evaluate and manage the individuals with FHP.

Objective : Associations of vascular risk/disease or apolipoprotein E ${\varepsilon}4$(APOE4) with geriatric depression has been unclear at a population level. This study aimed to evaluate whether there would be interactions of vascular risk/disease and APOE4 on depression in a Korean elderly population. Methods : 732 community residents aged 65 or over were assessed for depression(GMS), information on vascular risk/disease(reported stroke, transient ishemic attack, heart disease, hypertension, diabetes, smoking), examinations for vascular risk/disease(blood pressure, blood tests for glucose and lipid profiles, body size), APOE genotypes, demographic characteristics(age, gender, education), physical health, and cognitive function(MMSE). Results : Previous stroke and lower level of high density lipoprotein(HDL) cholesterol were significantly associated with geriatric depression independent of demographic characteristics, physical illnesses, and cognitive function. These associations were statistically significant only in those with APOE4, although the interaction terms didn't reach to statistical significance. Conclusion : Associations between vascular risk/disease and geriatric depression might be more prominent in those with APOE4. However further research would be needed to clarify this issue.

Recently, there has been significant interest in structural health monitoring for civil engineering applications. In this research, a specially designed tendon, proposed by embedding FBG sensors into the center king cable of a 7-wire strand tendon, was applied for long-term health monitoring of tensile forces on a ground anchor. To make temperature independent sensors, the effective temperature compensation of FBG sensors must be considered. The temperature sensitivity coefficient ${\beta}^{\prime}$ of the FBG sensors embedded tendon was successfully determined to be $2.0{\times}10^{-5}^{\circ}C^{-1}$ through calibrated tests in both a model rock body and a laboratory heat chamber. Furthermore, the obtained result for ${\beta}^{\prime}$ was formally verified through the ground temperature measurement test, expectedly. As a result, the ground temperature measured by a thermometer showed good agreement compared to that measured by the proposed FBG sensor, which was calibrated considering to the temperature sensitivity coefficient ${\beta}^{\prime}$. Finally, four prototype ground anchors including two tension ground anchors and two compression ground anchors made by replacing a tendon with the proposed smart tendon were installed into an actual slope at the Yeosu site. Tensile forces, after temperature compensation was taken into account using the verified temperature sensitivity coefficient ${\beta}^{\prime}$ and ground temperature obtained from the Korean Meteorological Administration (KMA) have been monitored for over one year, and the results were very consistent to those measured from the load cell, interestingly.

Purpose: To investigate the risk factors for anastomotic leakage (AL) after anterior resection for rectal cancer with a double stapling technique. Patients and Methods: Between January 2004 and December 2011, 753 consecutive patients in Jiangsu Cancer Hospital and Research Institute diagnosed with rectal cancer and undergoing anterior resection with a double stapling technique were recruited. All patients experienced a total mesorectal excision (TME) operation. Additionally, decrease of postoperative tumor supplied group of factors (TSGF), which have not been reported before, was proposed as a new indicator for AL. Univariate and multivariate analysis were performed to determine risk factors for AL. Results: AL was detected in 57 (7.6%) of 753 patients with rectal cancer. The diagnosis of anastomotic leakage was confirmed between the 6th and 12th postoperative day (POD; mean 8th POD). After univariate analysis and multivariate analysis, age (p<0.001), gender (p=0.002), level of anastomosis (p<0.001), preoperative body mass index (BMI) (p=0.001) and reduction of TSGF in 5th POD was less than 10 ${\mu}/ml$ (p<0.001) were selected as 5 independent risk factors for AL. It was also indicated that a temporary defunctioning transverse ileostomy (p=0.04) would decrease the occurrence of AL. Conclusion: AL after anterior resection for rectal carcinoma is related to elderly status, low level site of the tumor (below the peritoneal reflection), being male, preoperative BMI and the decrease of TSGF in $5^{th}$ POD is less than 10 ${\mu}/ml$. Preventive ileostomy is advisable after TME for low rectal tumors to prevent AL.

보행로보트에 있어서 다리의 기구적 특성은 안정도, 에너지 효율 및 걷는 영역 등에 영향을 준다. 보행로보트 중에서 안정도 여유가 비교적 큰 사각보행로보트는 보폭이 크다. 그리고 수직운동과 수평운동이 서로 분리되어 있는 팬토그래프 구조의 다리를 갖는 보행로보트는 기구적인 복잡성으로 인하여 움직임을 예상하기가 어렵게 된다. 따라서, 보행로보트의 3차원적인 이동을 해석하기 위하여 그래픽스를 이용한 방법이 중요하게 쓰일 수 있다. 본 논문에서는 서로 다른 조인트 구동방식을 갖는 세 개의 사각보행로보트를 모델링하고, 각각에 대하여 몸의 중심으로 표시된 경로로써 작업지시를 하여 걷는 모습을 애니메이션 함으로써 그 기구적인 특성을 해석할 수 있게 하였다. 그리고 회전걸음이나 옆걸음을 위하여 다리 제어를 하였고, 조인트의 이동에 대한 정보를 위하여 Sun-3 시스템에서의 윈도우를 이용하였다.
