This paper deals with the recognition algorithm of walking will based on torque estimation. Recently, concern about walking assistant aids is increasing according to the increase in population of elder and handicapped person. However, most of walking aids don't have any actuators for its movement. So, general walking aids have weakness for its movement to upward/download direction of slope. To overcome the weakness of the general walking aids, many researches for active type walking aids are being progressed. Unfortunately it is difficult to control aids during its movement, because it is not easy to recognize user's walking will. Many kinds of methods are proposed to recognize of user's walking will. In this paper, we propose walking will recognition algorithm by using torque estimation from wheels. First, we measure wheel velocity and voltage at the walking aids. From these data, external forces are extracted. And then walking will that is included by walking velocity and direction is estimated. Here, all the processes are verified by simulation and experiment in the real world.

It is difficult that we understand "Due to pathogenic Gi(因於氣)" in "Somun(素問) Saenggitongcheonron(生氣通天論)", because that is too many comments. We are to interpret Gi(氣) as Wind(風) or Anger(怒). However, the most reasonable explanation is to Yang-Gi weakness(陽氣虛). In other words, pathogenic Gi of four seasons should violate Yang-Gi(陽氣) and become a Yang-Gi weakness. Sayu(四維) can be interpreted as limbs[四肢], the last month of each of the four seasons[四季], four seasons[四時]. It is a logical view of the four seasons. This meaning is that it was already Yang-Gi weakness state by pathogenic-Gi of four seasons which violate Yang-Gi(陽氣), again the pathogenic Gi of four seasons violate Yang-Gi. As a result Yang-Gi will drain.

In this paper, we implemented a static analysis tool for weakness. We implemented on JavaCC using syntax information and control flow information among various information. We also tested the performance of the tool using Juliet-test suite on Eclipse. We were classified using information necessary for diagnosis and diagnostic methods were studied and implemented. By mapping the information obtained at each compiler phase the security weakness, we expected to link the diagnostic method with the program analysis information to the security weakness. In the future, we will extend to implement diagnostic tools using other analysis information.

The Blood paralysis(血痺) is infected by a poisonous factor of wind and it disturbs the circulation of meridian. This disease is similar phenomenon to the Blutsaure(血柱) and belongs to the category like the Radial nerve paralysis, the Ulna nerve paralysis and the unstability syndrome of the lower limbs. This dissertation will inquire into symptoms, the way of treatment and the prescriptions of this disease based on the Synopsis of Golden Chamber. The Weakness and fatigue(虛勞) is occurred by several causes. This disease means all the functions of body weakened. This dissertation will inquire into pulse conditions according to the type of the Weakness and fatigue(虛勞), symptoms, the way of treatment and the prescriptions of this disease based on the Synopsis of Golden Chamber.

Acute Transverse Myelitis is a syndrome, not a disease, in which acute inflammation affects gray and white matter in one or more adjacent thoracic segments. Almost all patients will develope ascending weakness and numbness of feet and leg, difficulty voiding, urinary retention, and loss of bowel control. We concluded this case to MAMOK( 마목) due to Qi ascent, Qi deficiency, Qi stoppage(상기, 기허, 기체). So we used herbal medication, acupuncture, and homeopuncture according to oriental medical theory. Weakness and numbness of feet and leg, difficulty voiding, urinary retention, and loss of bowel control are reduced. Herbal medication, acupuncture, and homeopuncture helped the care of this syndrome and further study will be investigated in oriental medicine for this syndrome.

RSA is one of the best well-known public key cryptosystems. This methodology is widely used at present because there is not any algorithm which can break this system that has all strong parameters within polynomial time. However, it may be easily broken when at least one parameter is weak. In fact, many weak parameters are already found and are solved by some algorithms. Some examples of weak parameters consist of a small private key, a large private key, a small prime factor and a small result of the difference between two prime factors. In this paper, the new weakness of RSA is proposed. Assuming Euler's totient value, Φ (n), can be rewritten as Φ (n) = ad + b, where d is the private key and a, b ∈ ℤ, if a divides both of Φ (n) and b and the new exponent for the decryption equation is a small integer, this condition is assigned as the new weakness for breaking RSA. Firstly, the specific algorithm which is created for this weakness directly is proposed. Secondly, two equations are presented to find a, b and d. In fact, one of two equations must be implemented to find a and b at first. After that, the other equation is chosen to find d. The experimental results show that if this weakness has happened and the new exponent is small, original plaintext, m, will be recovered very fast. Furthermore, number of steps to recover d are very small when a is large. However, if a is too large, d may not be recovered because m which must be always written as m = h^a is higher than modulus.

오늘날의 소프트웨어는 인터넷 환경에서 데이터를 교환하기 때문에 해커에 의해 악의적인 공격을 받을 가능성이 항상 존재한다. 이러한 보안약점은 심각한 경제적 손실을 발생시키는 소프트웨어 보안 침해사고의 직접적인 원인이다. 최근에는 보안 약점을 해소하기위해 외부환경에 대한 보안시스템을 견고히 하는 것보다 프로그래머가 견고한 소프트웨어를 개발하는 것이 보안 수준을 향상시킬 수 있는 본질적이고 가장 효과적인 방법이라는 인식이 늘어나고 있다. 이러한 가운데 코딩 단계에서부터 소프트웨어에 대한 취약점을 해소하여 보안 침해사고를 예방하기 위한 코딩 안내서를 제시하는 것이 전 세계적으로 주요한 보안 이슈로 떠오르고 있다. 시큐어 코딩을 개발자나 관리자 입장에서 효과적으로 사용하기 위해서는 전체 시큐어 코딩 집합과 보안약점을 구조적으로 체계화하고 관리해야 하며 새로운 정보의 갱신이 지속적으로 필요하지만, 기존의 시큐어 코딩 및 보안약점은 구조적으로 체계화되어 있지 못하다. 본 논문에서는 Java 언어를 대상으로 기존 시큐어 코딩 자료와 검사 도구의 코딩 룰 조사를 통해 보안 약점을 구조화하고 모바일 애플리케이션을 위한 구조적 보안 약점을 그 결과로 소개한다.

A cervical radiculopathy is the most common symptom of cervical degenerative disease and its natural course is generally favorable. With a precise diagnosis using appropriate tools, the majority of patients will respond well to conservative treatment. Cervical radiculopathy with persistent radicular pain after conservative treatment and progressive or profound motor weakness may require surgery. Options for surgical management are extensive. Each technique has strengths and weaknesses, so the choice will depend on the patient's clinical profile and the surgeon's judgment.

Backgrounds: Kennedy disease is a X-linked recessive disease characterized by bulbar symptoms, proximal muscle weakness, and gynecomastia. Methods: We analyzed clinical symptoms and performed electrodiagnostic studies on 6 patients. Results: We found following features: 1) proximal muscle weakness 2) bulbar symptoms, as dysarthria, facial and tongue atrophy 3) hyporeflexia or areflexia 4) fasciculations, predominantly on face, and proximal upper extremities 5) decreased sensory nerve action potentials(SNAPs) 6) chronic neurogenic changes in needle EMG. Conclusions: Kennedy disease is characterized by degenerative process of anterior horn cell and dorsal root ganglion without upper motor neuron dysfunction. Increased triple nucleotide CAG repeats(>38) in androgen receptor gene of Xp21 will confirm early stage of this disease.
