본 연구에서는 탐방로 안전성 평가 모델을 활용하여 21개 국립공원을 대상으로 안전지수와 등급분석을 수행하였다. 현장조사를 통해 탐방로 주변 위험요소 중 하나라도 확인되면 취약구간으로 판단하여 안전지수를 산출하였다. 취약구간은 총 180.4km로 조사되었으며 탐방로 총 연장 1,995.5km 대비 약 9.0%로 확인되었다. 안전지수는 총 200점 중 최소 42.3점에서 최대 167.0점 분포를 보이고 평균값은 101.5점으로 나타났다. 안전지수를 토대로 등급을 분석한 결과, ‘관심(Concern)’ 등급은 60.8km(34%), ‘주의(Caution)’ 등급은 57.8km(32%), ‘위험(Dangerous)’ 등급은 49.6km(27%), ‘매우위험(Very dangerous)’ 등급은 12.2km(7%)로 나타났다. 매우위험 구간은 북한산국립공원(6.0km), 지리산국립공원(3.3km), 오대산국립공원(1.6km), 설악산국립공원(0.9km), 월악산국립공원(0.4km), 속리산국립공원(0.01km) 등 6개 국립공원 탐방로에서 총 12.2km로 나타났다. 북한산국립공원은 Y계곡, 의상능선 등이 해당되며, 지리산국립공원은 칠선계곡, 구룡계곡에서 확인되었다. 오대산국립공원은 노인봉 일원, 설악산국립공원은 공룡능선, 흘림골 등에서 나타났다. 월악산국립공원은 금수산 일원, 속리산국립공원 막장봉 구간이 매우위험 구간으로 나타났다. 본 연구는 향후 재난위험 저감대책 수립과 탐방로 정비 우선순위 선정 등 국립공원 안전관리 정책을 수립하기 위한 기초자료로 활용될 수 있다. In this study, the safety indexing and grading analysis were conducted for 21 national parks, using the trail safety evaluation model. If any one of the risk factors around the trail was identified through a field survey, the safety index was calculated by judging it as a vulnerability zone. The vulnerability zone was 180.4km in total, and it was found to be about 9.0% compared to the total length of 1,995.5km. The safety index was distributed from the minimum of 42.3 to the maximum of 167.0, and the average value was 101.5 of total 200 scores. As a result of analyzing the grade based on the safety index, 60.8km (34%) was in the ‘Concern’ grade, 57.8km (32%) was in the ‘Caution’ grade, 49.6km (27%) was in the ‘Dangerous’ grade, and 12.2km (7%) was in the ‘Very dangerous’ grade. ‘Very dangerous’ sections were found to be a total of 12.2 km. including 6 national park trails: Bukhansan National Park (6.0km), Jirisan National Park (3.3km), Odaesan National Park (1.6km), Seoraksan National Park (0.9km), Woraksan National Park (0.4km), Songnisan National Park (0.01km). In terms of ‘Very dangerous’ section, Bukhansan National Park included Y Valley and Uisang Ridge, and Jirisan National Park included Chilseon Valley and Guryong Valley. The area of Noinbong in Odaesan National Park, and Gongnyong Ridge and Heulimgol in Seoraksan National Park were included. And the Geumsusan area in Wolaksan National Park and Makjangbong in Songnisan National Park were found to be ‘Very dangerous’. This study could be used as basic data to establish national park safety management policies, such as selecting priority of trail maintenance and establishing countermeasures to reduce disaster risk.

Analysis of Patients’ Consent Right in a Surgery -Triggered from the social event that a parturient in Yulin jumped off a tall building-

Hou, Jun-Ling 중국지역학회 2019 중국지역연구 Vol.6 No.1

The incident that a parturient jumped off a window of a hospital raised people’s reconsideration regarding the assignment of Patient Surgery Consent Right. Since the establishment of People’s Republic of China, this thought experienced three development phases: Administrative Instructions, Administrative Legislation, and the Legislation of National People’s Congress. Based on the consent of family members or interested parties, the right of consent mode, is violating not only the Patient’s right of free choice and informed consent, but the right of doctor’s special handling right. The author believes under non-emergency circumstance and the same kinship sequence, the Consent Right shall be assigned by the rule of rational reasoning, which presumed from blood relationship to the closeness of kinship and to closeness relation in actual life. In addition, author believes the right assignment shall be placed with the perspective of family members, interested parties and doctor’s special disposition, the law shall be amended from above mentioned aspects accordingly.

Jun Hou,Yanbao Zhao,Lei Sun,Xueyan Zou 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.114 No.-

Gold nanomaterials have attracted great interest in the fight against cancer due to their surface features. In this study, gold nanostar (GNS) cloaked with mesoporous silica (GNS@mSiO2) carriers were preparedfor controlled drug release. The GNS core presents a branched morphology with tip-to-tip diameter of80–120 nm and core of 40–60 nm. In this system, GNS not only served as photothermal agent but alsoas Raman signal enhancement matrix. After encapsulating doxorubicin (DOX) within the GNS@mSiO2carrier, hyaluronic acid (HA) was coated on the GNS@mSiO2 surface to seal the loaded-drug of channels. The obtained DOX-GNS@mSiO2/HA displayed pH/enzyme-triggered drug release and photothermalchemotherapeutic effect.

Hou, Jian Jun,Wu, Jing Tang,Du, Xi Yu 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1

This paper reports the dynamics and a great variety of one parameter bifurcation phenomena observed in the laboratory and confirmed by extensive computer simulations for the circuit reported firstly in [2]. The circuit consists of five elements, where the only nonlinear element is a common-base transistor pair with the characteristics of a current-controlled nonlinear resistor. Several strange attractors, the intermittent attractor, periodic windows, cascades of period doubling, period plus two and period minus one phenomena are observed by adjusting the value of L₁. The computer simulation results agree with the experiment results quite nicely. Hopf bifurcation is proved mathematically and the Lyapunov dimensions of several chaotic attractors are derived to confirm the existence of chaos.

Reduction of Peak-to-Average Power Ratio of Multicarrier Modulation Signals with Adaptive Companding Scheme

( Jun Hou ),( Xiangmo Zhao ),( Fei Hui ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.7

High peak-to-average power ratio (PAPR) of transmitted signals is a major drawback in Multicarrier modulation (MCM) systems. Companding transform is a well-known method to reduce the PAPR without restrictions on system parameters such as the number of subcarriers, frame format and constellation type. In this paper, a novel adaptive companding scheme, mainly focuses on compressing the large signals into the desirable distribution, is proposed to reduce the PAPR with low implementation complexity. In addition, formulas to calculate its PAPR and bit error rate (BER) performance are also derived. Simulation results confirm that the proposed scheme can achieve an effective tradeoff between PAPR reduction and BER performance by carefully choosing the companding parameter.

Ownership of a smartphone has never been easier nowadays, and it is supported by the fact that most of the people around us have a smartphone or an equivalent smart device. What is smartphone and why is it a smart? A smartphone by definition is as the name suggests, it is a phone is smart enough to not only be limited to the features and capabilities of a traditional cellular phone but also perform what a “smart” device can. And in recent years, the device that is deemed as the most intelligent device is the computer as it is the most advance piece of technology that is commercially available to the general public. Why this is so, is because in our opinion it has revolutionized how most if not all of the societies of today work. Hence what makes a smartphone is the mobile operating system that it is built upon, which is similar to a computer. It is becoming more and more of a common sight nowadays and this is because they are being offered at a price where more people are able to afford, hence they are reaching the hands of ceiling of the lower income families, all the way up to the higher income families. Back then, pure play devices were mostly simple in terms of how it function and works, hence if possible, we could suggest that the security aspect was never or rather has never been an issue other than the alteration of data after operation such as the tape of video recorders or images captured but never in the process, in the sense that there were no interruptions during operation, most likely is because it was clear and visible, but nowadays when you combine all of those devices into a complex entity, we tend to leave a hole in the cloth somewhere that we did not or rather can’t see due to the overwhelming amount of other things that we have. In this paper we discuss the current state of the commercially available operating systems of the two biggest names in smart devices, namely iOS and Android; and measure how secure and/or vulnerable (susceptible) are they to malwares and the nature of the mobile ad hoc network. We first analyze the integrity of the core of a smart device, the operating system and then use it to evaluate the effectiveness of their techniques and defenses of preventing and identifying malwares.

Background: Laparoscope-assisted gastrectomy in treating patients with gastric cancers developed with a background of highly invasive traditional surgery and is being increasingly performed in the Asian Pacific area. This study systemically investigated the technique and clinical results for comparison with traditional radical subtotal gastrectomy for gastric cancers. Methods: Clinical studies evaluating the effectiveness and side effects of laparoscope-assisted gastrectomy in treating patients with gastric cancers were identified using a predefined search strategy. Summary rates of effectiveness and side effects of laparoscope-assisted gastrectomy were calculated. Results: Thirteen clinical studies which including 1,412 patients with gastric cancer treated by laparoscope-assisted gastrectomy were considered eligible for inclusion. Systemic analysis showed that, for all patients, the pooled resection rate was 100%. Major adverse effects were anastomotic stenosis, abdominal abscess, abdominal bleeding, postoperative ileus. Treatment related death occurred in 0. 71% (10/1412). Conclusion: This systemic analysis suggests that laparoscope-assisted gastrectomy in treating patients with gastric cancers is associated with good curative rate and acceptable complications.
