The geology of Ulleung-Do is dominated by volcanic rocks with low strength and trachytic rocks with high strength but containing vertical joints that yield easily. Consequently, rockfalls along roadcuts are a major geological hazard, with the potential to affect the ring road of Ulleung-Do. In this study, we performed three types of rockfall hazard-risk assessment on the 3-km-long section of the ring road expected to have the highest possibility of rockfall. We used a rockfall ranking sheet in a roadside landslide hazard map, the Slope Stability Inspection Manual for National Highways (Japan), and a rockfall hazard rating system for inspection from the Japan Highway Public Corporation. We also employed the evaluation criteria of 'RHRS' developed by the Federal Highway Administration (FHA). An analysis of roadcuts at 27 sites with regard to geographic and geological conditions resulted in the identification of three classes of rockfall hazard (high, medium, and low). Of note, over 74% of slopes were assessed as high- and medium-class. Finally, a rockfall hazard map of the northeast region of Ulleung-Do was produced based on the evaluation results.

표 질의응답이란, 주어진 표에서 질의문에 대한 답변을 자동으로 추출하거나 생성하는 기술을 말한다. 최근 언어모델을 사용한 연구들은 정답을 유도할 수 있는 명령문인 프롬프트를 활용하여 더 높은 성능을 보이고 있다. 본 연구에서는 표 질의응답의 성능을 향상시키기 위해, 프롬프트를 효과적으로 사용할 수 있는 모델을 제안한다. 이와 함께, 다양한 형태의 프롬프트를 사용하여 모델을 평가한다. 실험 결과, 기본 모델에 단순 질의문만 입력으로 사용했을 때의 성능 F1 67.5%에 비해, 다양한 프롬프트를 입력으로 사용한 경우 1.6%p 향상된 F1 69.1%을 보였다. 또한, 다양한 프롬프트와 함께 제안 모델을 사용했을 때에는 기본 모델보다 2.2%p 높은 F1 69.7%을 달성했다.

Ten cleft palate patients were operated with reconstruction of levator sling without pushback for the purpose of not to make raw surface in the anterior portion of hard palate to prevent maxillary retrognathia. Speech was evaluated by using speech assessment list. Maxillary growth was not evaluated due to in-growing age in majority patient. The report will be followed in next chance. We could impose the significance in clinical application of levator sling palatoplasty without any complications but improving speech.

황금 닭의 해였던 2017년 한 해의 마침표를 찍었습니다. 매년 그렇지만 "이번 해가 끝나긴 하나?" 싶을 만큼 나라 안팎으로 참 다사다난한 한 해였습니다. 이는 축산물품질평가원도 마찬가지였습니다. 기분 좋은 성장을 하기도 했고, 또 씁쓸한 자기반성을 하기도 했습니다. 바쁘게 보낸 2017년, 축산물품질평가원의 365일의 기록을 "축산물품질평가원 10대 뉴스"로 되돌아봅니다.

Culverts are structures constructed across river levees. Since river levees are to be constructed continuously, constructions of culvert are known to reduce the stability of river levees. In order to establish an effective inspection system of culverts, a visual inspection system using checklists and smart phone was recommended in this paper. It was determined that the recommended visual inspection checklist is applicable in establishing the investment priority based on the culvert's repair plan establishment, repair and precision safety inspection.

최근 정보기술의 발전과 인터넷 서비스의 급속한 성장 둥으로 인하여 다양한 분야에서 웹 사이트가 운용중이며 품질의 중요성도 점차 인식되어지고 있다. 또한, 운용중인 웹 사이트 품질평가를 위해 적용할 품질모형 및 품질정가 프로세스는 평가대상 웹 사이트의 특성을 고려하여 선정이 요구된다. 따라서, 본 논문에서는 ISO/IEC 9126-4, WebQEM, 2QCV3Q, KNDU-SQEP를 적용하고, 미흡한 품질속성을 보완하기 위해 웹 사이트 품질평가를 위한 품질모형과 품질평가 프로세스를 제시하였다. 또한 웹 사이트 제품 평가 모델의 품질평가 점검표를 작성하여 포털 및 전문업무 사이트에 적용하고 WebQEM 모텔과 제안한 모델의 평가치를 비교하여 운용중인 웹 사이트에 대하여 평가가 가능한 것을 입증하였다. 향후에는 개발 중의 중간 산출물에 대한 품질평가 점검표의 개발을 통하여 전 수명주기에 대한 지원이 요구된다.

To evaluate the usefulness of 3-dimensional brachytherapy(BT) planning technique based on CT in cervical cancer. Patients with cervical cancer underwent 2-D BT treatment planning and then CT scan with HDR intracavitary applicators in place with same positions. Dose was prescribed to Point A with 5Gy per fraction on 2-D BT planning. For 3-D BT planning, and dose was prescribed to the High risk CTV for BT (HR CTV) with 5Gy. The 3-D BT planning goal was to cover at least 90% of the HR CTV with target 5Gy isodose surface while limiting the dose to $2cm^3$ of bladder to less than 7.5 Gy, and $2cm^3$ of rectum to less than 5Gy. In one patient of 10 patients, $D_{2cm3}$ of rectal dose was over 5Gy and 6patients at $D_{2cm3}$ of bladder dose on 2-D BT planning. There was a tendency to underestimate ICRU bladder dose than ICRU rectal dose. CT based 3-D BT planning for cervical cancer will enable evaluation of dose distributions for tumor and critical organs at risk. So, rectal and bladder morbidity as well as geographic miss will be reduced in case of the bulky disease or uterine malposition.

Purpose: This study evaluated the validity of a physical activity classification table (PACT) based on total energy expenditure (TEE) and physical activity level (PAL) measured using the doubly labeled water (DLW) method in Korean adults and the elderly. Methods: A total of 141 (male 70, female 71) adults and elderly were included. The reference standards TEE_DLW, PAL_DLW were measured over a 14-day period using DLW. A 24-hour physical activity diary was kept for three days (two days during the week and one day on the weekend). PAL_PACT was calculated by classifying the activity type and intensity using the PACT. PAL_PACT was multiplied by resting energy expenditure measured by indirect calorimetry to estimate TEE_PACT. Results: The mean age of the study participants was 50.5 ± 18.8 years, and the mean body mass index was 23.4 ± 3.3 kg/m². A comparison of TEE_DLW and TEE_PACT by sex and age showed no significant differences. The bias, the difference between TEE_DLW and TEE_PACT, was male 17.3 kcal/day and female -4.5 kcal/day. The percentage of accurate predictions (values within ± 10% of the TEE_DLW) of TEE_PACT was 58.6% in males and 54.9% in females, with the highest prediction values in the age group 40-64 years (70.9%) in males and over 65 years (73.9%) in females. The spearman correlation coefficient (r) between TEE_PACT and TEE_DLW was 0.769, indicating a significant positive correlation (p < 0.001). Conclusion: In this study, the use of a new PACT for calculating TEE and PAL was evaluated as valid. A web version of the software program and a smartphone application need to be developed using PACT to make it easier to apply for research purposes.
