인체 공중 동작 시뮬레이션 프로그램 개발

성낙준,권영후 한국운동역학회 1994 한국운동역학회지 Vol.4 No.2

A comprehensive simulation software package was developed in C base on the work done by Yeadon et al.(1990) and Kwon (1993a) in the aim of making it easy to apply the experimental simulation technigues to the human airborne movement studies. This package consists of 3 programs: simulation variable computation program (PREP), simulation program (SIM) and the 3-dimensional graphic program (3DMAN). All programs are driven by an easy-to-use menu system and written compatible to KWON3D Motion Analysis Package Version 2.1 (Kwon, 1993b). Program PREP consists of 4 menus: `Edit Data´, `Prepare´ `Angular Momentum´ and `Optimization´. The `Edit Data´ environment is an editor for the lengths of the segments and body lines. The `Prepare´ menu computes the internal orientation angles of the segments while the `Angular Momentum´ menu computes the mean airborne angular momentum of the body and other initial conditions such as the initial position and velocity of the body CM and the initial external orientation of the body. The `Optimization´ menu performs angular momentum optimization proposed by Kwon (1993a). A geometric 15-segment body model - Yeadon-Kwon model (Kwon, 1993b) - with at most 38 degrees of freedom including 3 external orientation angles (somersault, inclination and twist angles) was employed to compute the simulation variables. SIM consists of 2 menus: `Edit Angles´ and `Simulate´. The `Edit Angles´ environment is an editor for the internal orientation angles of the segments. Users can intentionally manipulate the internal orientation angles for the simulation of modified trials. The program displays time-angle curves segment by segment. The `Simulate´ menu actually performs simulation. The initial conditions can be directly manipulated in the program menu environment. The simulation program was tested by several theoretical configurations to screen out the flaws in the theory and to isolate coding mistakes. The simulated results were compared with the predicted results and the program showed good agreements between the simulated results and the theoretical predictions. The simulation program was then applied to several gymnastic maneuvers and springboard dives for testing. 3DMAN was developed in the extension of the traditional `Stick Figure´ graphics. The program is segment-oriented and the 3-D shape of each segment is defined defined independently in a graphic model file to allow the users to use different body models with different, combinations of segments. The model file was designed easy to edit so as to allow the users to change the graphic model easily to meet their specific needs. The graphic model file can be edited using any text editor such as `EDIT´ of DOS. Once the `3-D Graphics´ option is activated followed by the registration of the graphic model files, the program draws the 3-D shapes of the segments whose model files are registered. All the graphics-related menus including registration of the segment graphic model files are accessible within the graphic environment.

The formation of charge transfer complex between iodine and aniline in CHCl₃CHCl₄: CH₂Cl₂(1:1), CH₂Cl₂have been studied kinetically by using conductivity method. The initially formed outer charge transfer complex was transformed into a inner charge transfer complex. The pseudo first order rate constants and activation entropy are affected by solvent dielectric constant. The second order rate constants for the decomposition of the outer charge tranfer complex (first order in aniline and in the outer charge transfer complex) depend on the aniline concentration. The ease with which the transfermation proceeds depends on the relative magnitudes of the enthalpy of formation of the outer charge transfer complex as well as aniline concentration.

權赫茂,朴相俊,金水泳 충남대학교 공업교육연구소 1982 論文集 Vol.5 No.2

Bainite spheroidal graphite cast iron specimens of 0∼0.054wt % residual Mg were casted into a green sand mold, 25 mm thickness Y-block. The microstuctures of the castings were studied for mechanical properties and abrasion characteristics. The results obtained from this study are summerized as follows: 1) Under the present expermental conditions, the relation between the abrasion speed and the abraded amount are; 0.5m/sec for 1^st abrasive wear and 2.38m/sec for 2^nd abrasive wear. 2) Increasing the residual Mg, the first abrasion speed for 2nd abrasive wear moved to the low abrasion speed. 3) The maximum amount of abraded material during 2^nd abrasive wear decreases with the increasing residual Mg content, and moves to the high abrasion speed as the residual Mg is increased over 0.042 wt %. 4) The amount of abraded materials increases with the decreasing residual Mg at abrasion speed 2.38 m/sec and with the increasing residual Mg at abrasion speed 0.62∼1.14 m/sec. 5) Increasing the abrasion speed, abrasion mechanisms are as follows; ⓐ 1^st abrasive wear ⓑ 1^st corrosive wear ⓒ 2^nd abrasive wear ⓓ 2^nd corrosive wear. But, Under the present expermental condition the adhesive wear mechanism didn't appear.

저자들은 급성 림프구성 백혈병 환자에서 항암치료 후 호중구감소증이 지속되는 상태에서 침습성 아스페르길루스증의 드문 형태인 치명적인 아스페르길루스 기관기관지염을 경험하고 문헌고찰과 함께 증례를 보고하는 바이다. Tracheobronchial aspergillosis is an uncommon clinical form of invasive aspergillosis, particularly found in patients with AIDS and in lung transplant recipients than in other immunocompromised patients. The rapidity of the disease progression can result in fatal airway obstruction in a short period of time that the patient may need emergency tracheostomy without knowing the cause of the obstruction. We describe a case of fatal tracheobronchial aspergillosis which developed in a 43-year-old female patient with acute lymphoblastic leukemia. Dyspnea and stridor developed on the 20th day after 2nd consolidation chemotherapy, which was during the prolonged neutropenic period. Airway narrowing was observed on the computed tomograph scan of neck and emergency tracheostomy was performed. Infiltration with aspergillus hyphae was found in the tracheal ring and bronchial mucosa. Despite the use of amphotericin B, the patient died of bleeding and airway obstruction.

In this study, visual recognition of X-ray images were estimated using hawlet charts. The resolution has achieved excellent result when densities of film were 1.0~1.5. The more thickness of object was increase, the more the resolution was decrease, because scattered X-ray were increased. The more distance of object to film was increase, the more the resolution was decrease, because groedel effect. The more focal spot size was increase, the more resolution was decrease, because unsharpness was increase. The more field size was increase and grid ratio was decrease, the more resolution was decrease, because scattered X-ray were increase. As a result, we could to improve image quality by determination of resolution according to Radiography parameters. And, we proved that hawlet charts were useful for estimate of image quality and set up x-ray radiography.

Objective : In view of the facts that education about diseases and realization of the need form drugs can improve compliance of the patients, we assessed the knowledge about drugs and medication compliance in psychiatric outpatients. In addition, we investigated factors that influence patients compliance to develop a model of medication compliance. Methods : One-hundred twelve male and eighty female psychiatric outpatient were asked about drug information using questionnaires. We developed a model that predicts medication compliance using chi square tests and multiple regression analysis. Results : More than a half of the patients knew at least one of the names and the effects of the drugs they had taken, but many of them didn't know the side effects of drugs. About eighty percent of the patients showed good compliance. Knowledge of side effects, belief in the benefits of drugs, and level of education could predict medication compliance reliably. Conclusions : Because education level could not be managed by physician, we could enhance compliance through education about drug side effects and benefits of medications.
