We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

In this paper we investigate and analyze the variation of secondary school student's like and dislike the school mathematics lesson. First, we investigate the reason that why students dislike mathematics in the class and we search the point of time when the students dislike mathematics in the class. Next, we investigate and analyze the variation of student's inclination to the school mathematics lesson. In this research we try the followings. 1) We analyze the variation of each level school, student's inclination to the school mathematics class, 2) We analyze the variation of student's inclination to the mathematics for each place where the school located. 3) We analyze and compare between the inclination to the mathematics lesson and to each level school. 4) We analyze and compare between the inclination to the mathematics lesson and to each factors of student's inclination From these investigation and analysis, we have the following conclusion . (1) The student's inclination to the mathematics is depend on the teacher's teaching method and on the fact that how can the mathematics lesson be composed easily. (2) The student's response was seen in the same type from the inquiry about the inclination to the mathematics lesson in the school of Seoul and small country town. This is a passing phase caused by the educational environment in Seoul and the small country town's schools is better than that of the big city or medium city. (3) The student group of the human knowledge in the general high school show the negative response for the inclination to the matheirlatics lessen compare to that of the student group of natural science in the general high school. (4) In the middle school, about half of the students dislike mathematics But such dislike rate of mathematics increased in the high school. (5) Teachers must take into consideration to the student in the first grade high school mathematics course To do this, teachers make adapt the curriculum easily for the student and must teach the mathematics to the students who can take interest in the mathematics.

Jae‑Young Park,Kwangsuk Park,Bosung Seo,Julien O. Fadonougbo,Tae‑Wook Na,Ki Beom Park,Hyeon‑Tae Im,Nong‑Moon Hwang,Hyung‑Ki Park 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.7

This study examines the insulation coating technology of Fe–Si–Cr powder via selective oxidation annealing, which oxidizeselements selectively by controlling the oxidation potential. The study calculated the oxidation driving force of Fe, Si, andCr, and conducted a thermodynamic analysis of oxidation and reduction conditions according to temperature and oxidationpotential. Based on the results, a selective oxidation annealing was performed in an atmosphere in which Fe is reduced andonly Si and Cr are selectively oxidized. The oxidation potential was controlled through the partial pressure ratio of hydrogenand water vapor. The XPS analysis results confirmed that a Si and Cr complex oxide layer formed on the powder surfaceafter the selective oxidation annealing. Afterward, withstanding voltages were analyzed to evaluate the insulation property. Then, the withstanding voltage of the powder applying the selective oxidation annealing increased significantly comparedto that of the initial powder. Further analysis showed that the powder annealed in an air atmosphere had a significantly lowersaturation magnetic flux density than the initial powder, while the powder applying the selective oxidation annealing hadonly a slightly reduced saturation magnetic flux density.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

목적 : 항암화학요법 중 호중구감소증을 동반한 발열이 발생하는 암환자들을 치료하기 위한 다양한 항균제와 여러 가지 방법들이 시도되고 있는 가운데, 합병증과 사망률의 발생가능성이 적은 저위험군 환자들을 대상으로 초기 72시간동안 정주 항균제를 투여한 이후 경구 항균제로 전환하는 요법의 유용성과 안정성을 평가해보고자 본 연구를 시행하였다. 방법 : 1998년 2월부터 1999년 9월까지 본원에서 항암화학요법 중 호중구감소증과 발열이 발생한 환자들 가운데 기저 암질환이 고형암이거나 림프종이고, 입원당시 패혈증의 증후가 없으며 입원 72시간이내에 해열되고 백혈구수치가 증가 추세인 환자들을 대상으로 하여 72시간 동안 정주 항균제를 투여한 이후 경우 ciprofloxacin 750㎎을 하루 2회씩 투여하여 총 4일간 투여하였다. 모든 환자들은 열이 떨어지고 호중구감소증이 회복될 때까지 입원하도록 하였다. 결과 : 총 38명 환자의 40예가 등록이 되었고, 환자들의 기저암 질환은 고형함이 72.5%, 림프종이 27.5%였다. 입원당시 평균 호중구치수는 156/㎕였고, 호중구수치가 100/㎕미만인 경우는 65%였으며, 호중구감소증이 지속된 기간의 평균은 2.4일이었다. 40예 중 39예가 항균제의 변형이나 추가 없이 호중구감소증과 발열로부터 회복이 되어 97.5%의 성공율(95% 신뢰구간: 86.8-99.9%)을 보였다. 부작용으로 피부발진이 있었던 경우가 한 예 있었는데, 증상이 경하여 경구 항균제를 지속할 수 있었다. 심와부의 동통으로 복용을 지속할 수 없어서 대상에서 제외된 예가 또 한 예 있었다. 결론 : 항암요법 중 호중구감소증과 발열을 동반한 환자들 가운데 저위험군 환자들에서 항균제 72시간정주 이후 경구 항균제로의 전환요법은 효과적이고도 안전한 치료방법이라고 할 수 있다. Background : Oral antibiotic therapy following empirical intravenous antibiotics may be effective and safe for febrile neutropenic patients with lowrisk for complications. Methods : We conducted a prospective clinical trial of oral antibiotic therapy in the patients with neutropenia and fever during chemotherapy for cancer. Underlying malignancies were solid tumor or lymphoma with short duration of neurtropenia and the patients had no evidence of clinically or microbiologically documented infections. Oral ciprofloxacin was given to the patients who lacked signs of sepsis on admission, had a rising tendency of neutrophil count (ANC >100 /㎕ ) at 72 hours, and were afebrile at 72 hours. All patients were hospitalized until neutropenia and fever resolved. Results : A total of 40 episodes of 38 patients were enrolled from February 1998 to September 1999. The mean neutrophil counts on admission were 156/㎕ and the mean duration of neutropenia was 2.4 days. The episodes which had neutrophil count below 100 /㎕ were 26 (65%). Treatment was successful in 39 of 40 episodes (97.5% : 95 % confidence interval, 86.8% to 99.9%). Adverse reactions of oral ciprofloxacin were skin rash and epigastric soreness in two cases, respectively. There were no deaths during the study. Conclusions : For low-risk febrile patients with neutropenia during cancer chemotherapy, switch therapy to oral ciprofloxacin at 72 hours following intravenous broad-spectrum antibiotics is effective and safe,
