本稿では、名古屋市で創業し、葬蔡業においてイノベーションを起こしたティア社の事業を、既存企業と比較し、分析を行う。サービスのイノベーションには、新たなサービスの開発によるものと、サービスの内容はこれまでと大きな違いがないが、それを新しい事業システムによって展開する「事業システムのイノベーション」がある。ティアは、葬蔡業において、「事業システムのイノベーション」を起こした企業である。本稿では、既存企業とティアの事業システムの違いを、財(サービス)、資本、労働、情報の取引の観点から分析を行う。企業家の輩出やイノベーションの生起の頻度、その受容と普及の速度については、地域間で大きな差異が存在する。日本の多くの地域では、企業家の輩出が停滞し、イノベーションが生起しにくい状況となっているが、そのような地域においても、「事業システムのイノベーション」の可能性が存在することを、ティアの事例から提示する。

We report a patient with jaw trismus demonstrating Square-Mandible face.<BR>Clinically, the patient had a square face with prominent masseter muscles and mandibular angles. The interincisal opening was 26mm, with limited lateral and anteroposterior mobility.<BR>The clinical diagnosis was restricted mouth opening due to bilateral hyperplasia of the masseter muscle aponeuorses. Masseter muscle myotomy with aponeurectomy was performed bilaterally by an intraoral approach. Mouth opening improved to 40mm after incision of the aponeuroses.<BR>An examination of the patient one year after surgery demonstrated an interincisal opening of 37mm without strain.

Although Black Americans had long served in the racially segregated United States Army prior to World WarII, there were no Black pilots in the Army Air Force (AAF) or its immediate predecessor, the Air Corps. TheAAF resisted previous efforts to enlist Black airmen with the claim that there were no Black pilots in theUnited States. Previous efforts to enlist Black airmen were met with the claim within the War Departmentand the AAF in general that Black Americans lacked the aptitude to be military pilots. It was not until thepassage of the Selective Training and Service Act of 1940 that the AAF, along with other military services,was required to enlist Black males in proportion to their percentage (about 10 percent) of the total population.According to Charles Dryden, Tuskegee Airmen were individuals who were involved in the so-calledTuskegee Experiment by the U.S. War Department to train Black Americans to fly and to maintain airplanesin flying condition, from 1941 to 1946, including persons stationed or employed at Tuskegee Army Air Fieldand / or Moton Field, in various roles and statures: flying officers, nonflying officers, nurses, aviation cadets,noncommissioned officers, enlisted men and women, and civilians. However, according to LeRoy Gillead, theperiod definition is not from 1941 to 1946, but from 1939 to 1949. It was in 1939 that Black Americans werepromoted in aviation through Public Law 18 and the Civil Pilot Training Act. Further, 1949 was the year inwhich many Tuskegee Airmen left Lockborne Air Force Base and were transferred to white Air Force Base.Black Soldiers in World War II had to fight against enemies overseas and discrimination within the UnitedStates. In 1939, there were 1359 white officers in the Army, but only 5 Black officers. Three were chaplainsand the other two were Benjamin Davis, Sr. and Benjamin Davis, Jr. Almost 1000 Black Americans finishedPilot Training. 450 Black Pilots and many Black Ground Supports went overseas in combat roles. TheTuskegee Airmen who remained in the United States fought against discrimination in incidents such as theFreeman Field Incident. The Tuskegee Airmen fought for the advancement of the status of Black Americans20 years before the Civil Rights Movement in the United States.

法的推論システムの実現には,法令文のルール知識に加えて判例を描写するイベント(一回性の事象)のための表現手段が必要である.特に,判例の中身は複数のイベントによって展開されており,動的な知識表現とその論理的な推論を法的推論システムに取り込まなければならない.イベントは一回性・一時性を持った動作あるいはアクションであり,静的なプロパティと対比される概念である.これまでイベントの概念は,オントロジ,論理学,言語学,人工知能,演繹データベースなど様々な研究分野で扱われてきているが,各アプローチとも法的推論でのイベント記述の多様な側面を同時にとらえるには不十分であった.本論文では,法的推論で現れる語彙や記述を例に用い,イベントの量化,ソート階層およびイベント間の合成と排他性を導入した知識表現とその論理型言語(イベント論理と呼ぶ)を提案する.この言語は,順序ソート付き二階述語論理に準じた論理的な表現によってイベントを定数,ソート,述語および変数と見なし,イベント言明のための知識表現と推論を可能にする.さらに,法的推論システムを実現する推論メカニズムの基盤を与えるために,イベント論理に対するソート付きのタブロー計算を設計して,その反駁推論による質問応答システムを構築する.In order to implement a legal reasoning system, we have to provide a method that represents the suitable descriptions of events in addition to legal concepts and rules. An event, as opposed to an atemporal property, has its own time and location, and happens once and for all. Although the notion of events has been found in the researches of ontology, logic, linguistics, artificial intelligence and deductive databases, each approach does not seem to capture the various aspects of events represented in legal reasoning. In this paper, we propose an event logic with such expressions as quantification over events, event sort-hierarchy and composition and disjointness of events, based on some examples on event descriptions in legal knowledge. This logic is a variant of order-sorted second-order logic formalized by regarding events as constants, sorts, predicates and variables, which provides knowledge representation and reasoning for event assertions. In order to obtain a query-answering system, we present a sorted tableau calculus for refutation of event formulas in the logic.

Objective: To evaluate the usefulness of diagnostic laparoscopy in patients with advanced ovarian cancer.Methods: We retrospectively analyzed nine patients for whom primary debulking surgery was considered unfeasible. We evaluated whether laparoscopic procedure was adequate in making pathological diagnosis and intraabdominal assessment.Results: Median age was 63 years (range, 47-79 years), and median operation time was 59 minutes (range, 43-103 minutes). All nine patients were pathologically diagnosed with high-grade serous carcinoma and were considered unfit to undergo primary debulking surgery. All patients received chemotherapy. Six patients underwent interval debulking surgery. Only one patient showed mild adhesions between the omentum and the abdominal wall. Conclusion: Diagnostic laparoscopy is safe and feasible in advanced ovarian cancer patients.

Minimally invasive surgery (MIS) which thinks a great deal of patient’s quality of life (QOL) has attracted attention during about ten years. In this paper, it aims at development of the technology for transmitting force sensation required in medical treatment especially through surgical instruments, such as forceps. In bilateral control, it is a problem how master and slave robots realize the law of action and reaction to the environment. Mechanism of contact with environment and bilateral controller based on stiffness are shown. Master arm in contact with human and slave arm in contact with environment are given compliance, and stable contact with environment can be realized. The proposed method is applied to 3-link master-slave manipulators. As a result, transmission and reproduction of force sensation can be realized. The experimental results show viability of the proposed method.

We investigated the electrostatic charging phenomena of polymer films used for the thermal control materials of spacecrafts by electron-beam irradiation simulating the hot plasma in space. Three kinds of polymer films, Teflon FEP (flurinated ethylene-propylene), Kapton PI (poly imide) and Mylar PET (poly ethylene telephthalate) of the thickness of 13-75μm, were tested under the irradiation conditions of the electron energy E lower than 50keV and the beam current density Jb lower than 1nA/cm2. The surface potentials Vs of the films were obtained as functions of E and Jb at the constant irradiation time.The obtained experimental results are as follows.(1) Vs increases with increase of Jb. When Vs∞Jbn is assumed, the n value is different during the films: n=1 for FEP film, n_??_0.5 for PI film and 0.5_??_n_??_0.8 for PET film.(2) In Vs-E characteristics, Vs has the peak at some electron energy which is dependent on the material and the thickness.These results were explained by an one-dimensional charging model in which one charge deposition layer is assumed to be formed in the bulk of the film and the volume resistivity and the secondary electron emission coefficient of the material are considered.
