Since most of information is computerized nowadays, it is extremely important to promote the security of the computerized information. However, the software itself can threaten the safety of information through many abusive methods enabled by coding mistakes. Even though the Secure Coding Guide has been proposed to promote the safety of information by fundamentally blocking the hacking methods, it is still hard to apply the techniques on other programming languages because the proposed coding guide is mainly written for C and Java programmers. In this paper, we reclassified the coding rules of the Secure Coding Guide to extend its applicability to programming languages in general. The specific coding guide adopted in this paper is the C Secure Coding Guide, announced by the Ministry of Government Administration and Home Affairs of Korea. According to the classification, we applied the rules of programming in Sprout, which is a newly proposed Korean programming language. The number of vulnerability rules that should be checked was decreased in Sprout by 52% compared to C.

We propose an improvement on the Guideline of Secure Software Development for Korea e-Government that is under revision by the Ministry of Public Administration and Security in 2012. We adopted a rule-oriented organization instead shifting from the current weakness-oriented one. The correspondence between the weakness and coding rules is identified. Also, added is the coverage of diagnostic tools over the rules to facilitate the usage by programmers during coding period When the proposed guideline is applied to secure software development, the weakness would be controlled indirectly by enforcing coding rules. Programmers responsibility would be limited to the compliance of the rules, while the current version implies that it is programmers responsibility to guarantee being free from the weakness, which is hard to achieve at reasonable cost.

Two stroke low speed diesel engines are mainly used for marine propulsion or power plant prime mover. These have many merits such as higher thermal efficiency, mobility and durability. However various annoying vibrations sometimes occur in ships or at the plant itself. Of these vibrations, torsional vibration is very important and it should be carefully investigated during the initial design stage for engine's safe operation. In this paper authors suggest a new estimation method of for shaft's can be calculated equivalently from accumulated fatigue cycles number due to torsional vibration. The 6S70MC-C($25,320ps{\times}91rpm$) engine for ship propulsion was selected as a case study, and the accumulated fatigue cycles numbers for shafting life time converted from the measured angular velocity and torsional vibration stress was calculated. This new method can be realized and confirmed in test model ship with two stroke low speed diesel engine.

With urbanization projects involving trunk roads progressing, many simple interchanges, which separate passing traffic into the main traffic and access subtraffic, are being constructed to maximize the traffic capacity. Under the current Road Connection Rule, the access-prohibited section in an interchange is determined based on the access lane and limit distance in the complete interchange road, but separate criteria for the simple interchange are not defined. This may cause confusion in the Road Management Office's determination of the access-prohibited section in the simple interchange, or lead to the application of the criteria for the access-prohibited section in the complete interchange without considering the features of such interchange. This study conducted a comparative analysis of the domestic and overseas systems related to the installation of access section in trunk roads, such as general national roads. This paper presents a survey of the methods for applying the access-prohibited section in the interchange along with the actual cases and proposes improvement measures for a rational calculation of the access prohibited installation section in the simple interchange to minimize the downsides associated with the application of the extremely strict criteria. The proposed road connection rule improvement measures based on the consideration of the purpose of installing the simple interchange and on the consideration the features of the simple interchange are expected to prevent administration confusion by the field road management offices as well as the waste of unnecessary efforts and costs by petitioners so they can boost the service satisfaction for people and the administrative reliability.

In this study, we examined classroom interaction to explore the relationships among teacher questions, turn-taking patterns, and student talks in mathematics classrooms. We analyzed lessons given by three elementary teachers (two first-grade teachers and one second-grade teacher) who worked in the same school using a conversation-analytic approach. We observed individual classrooms three times in a year. The results revealed that when teachers provided open-ended questions, such as "why and how" questions and "agree and disagree" questions, and used a non-IRE pattern (teacher initiation-student response-teacher feedback; Mehan, 1979), students more actively engaged in classroom discourse by justifying their ideas and refuting others' thinking. Conversely, when teachers provided closed-ended questions, such as "what" questions, and used an IRE pattern, students tended to give short answers focusing on only one point. The findings suggested teachers should use open-ended questions and non-IRE turn-taking patterns to create an effective math-talk learning community. In addition, school administrators and mathematics educators should support teachers to acquire practical knowledge regarding this approach.

2023년 우리나라에 발생한 재난은 남부지방의 가뭄, 태풍 카눈에 의한 폭우, 7월~9월 폭염 등의 자연재난과 4월 5일 분당 정자교 붕괴, 4월 29일 검단신도시 붕괴사고, 7월 13일 대구 염색산업단지 황산 누출 등의 사회재난이 발생하였다. 이전 2022년에는 022년 10월 29일, 서울 이태원역 부근에 대규모 인파가 한번에 몰리며 압사사고가 발생하여 159명이 목숨을 잃고 196명의 부상자가 발생하였다. 이처럼 다양한 형태로 발생하는 재난에 대하여 우리나라는 「헌법」과 「재난 및 안전관리 기본법」에서 재난으로부터 국민의 생명·신체 및 재산과 국가의 피해를 줄이기 위해 노력하여야 한다고 명시하고 있다. 재난은 다양한 특성을 지니고 있으며, 학자들의 일반적 견해는 누적성, 불확실성, 복잡성, 인지성 등의 특성을 들고 있다(재난관리론, 2020). 특히, 사회재난은 발생위치, 시점, 피해, 규모를 예측하기가 상대적으로 매우 어렵기에(장대원 외, 2019) 불확실성의 특성을 강하게 보여주고 있다. 이러한 사회재난의 특성은 자연재난과 비교하여 사람들에게 물리적·심리적 영향을 크게 미칠 뿐만 아니라 단기간에 회복하기 어려운 특성을 지닌다(신재헌 외, 2020). 이에 대하여 많은 국민들은 심각한 사회재난이 발생할 때마다 정부차원의 적극적 재난관리 및 통제능력 향상을 요구하고 있으나, 사회재난 특성 상 특정 기관 중심으로 대응하기에는 많은 어려움이 있다(신재헌 외, 2020). 우리나라 경찰은 2021년 7월부터 자치경찰제도를 실시하며 국민의 생명·신체 및 재산의 보호, 범죄예방, 수사 및 질서유지업무 이외에 국민들의 봉사·서비스 행정 요구의 증대로 인한 적극적·능동적 경찰활동으로 변화하게 되었다(조호대, 2014). 이에 따라 경찰은 경찰의 재난관리체계를 확립하고, 경찰의 재난관리에 관한 사항을 규정함을 목적으로 2012년 「경찰 재난관리규칙」을 제정하였다. 이에 본 연구에서는 경찰의 재난 발생 시 역할이 무엇이며, 특히 사회재난 시 경찰의 적극적 대응 방안은 무엇인가에 대하여 살펴보고자 한다.

This study suggested the methods of record management for the heads of local government, which would be the most valuable among local records. In order to conduct a systematic record management for the heads of local government, this study suggested the methods of establishing a record management system regarding regulation arrangement, production registration, preservation, utilization and services. First of all, in order to estimate the record category of the heads of local government, the study examined the duties of the offices of the deputy heads of local government, secretary's offices and information offices, which have been subsidiary & assistance branches in charge of producing the record. In addition, it investigated the present conditions of record management for the heads of local government through the interviews with secretary offices and information offices belonging to 16 cities and provinces and the claims for information disclosure and found out the following problems. They included incomplete record production, non-registration of produced records, abolition of records and taking them out of designated places with due notice, record preservation period regardless of the term of the heads of local government, varied preservation period for the records of the heads of local government by local self-government, short preservation period of primary records and non-management of home pages after the term of the heads of local government. To solve such problems, the study suggested the regulation arrangement for record management and a record management system. The regulation arrangement could be obtained through the establishment of the administrative organization setup condolence etiquette enforcement regulation and the recorders in local government and the revision of operation rules and through the revision of the reference plan for operation rules enactment of recorders from National Archives of Korea. As for the record management system, the study suggested the establishment of production, registration and preservation system of records for the heads of local government and the utilization and services of their records. In order to produce and register the records, the unit assignments should be founded by department in charge of the duties related to the records of the heads of local government on record management criteria, thus letting the staff surely produce and register the records. In terms of utilization and services of the records, the study suggested the use of websites and drawing up the record list, through which each record viewer would be able to figure out which records have been managed through the list services and which services could be given to the residents, thus letting the residents and the heads of local government who finished their term of duties use the records.
