Purpose: To evaluate the clinical outcomes of a new refractive corneal lenticule extraction method (SmartSight) using a Schwind ATOS femtosecond laser (Schwind Eye-Tech-Solutions, Kleinostheim, Germany). Methods: The medical records of 338 eyes of 170 patients who underwent SmartSight treatment from April to September 2022 and were followed-up for at least 3 months were retrospectively analyzed. The patients were followed-up at 1 day, 1 week, and 1 and 3 months after operation. Refraction, visual acuity, and intraocular pressure were measured at each visit. Results: Preoperatively, the uncorrected distant visual acuity was 1.26 ± 0.33 logarithm of minimum angle or resolution (logMAR) and the spherical equivalent was -4.52 ± 1.77 diopters. The 3-month, postoperative, uncorrected distant visual acuity was 0.01 ± 0.03 logMAR and the spherical equivalent was -0.12 ± 0.22 diopters. The 3-month data were as follows: efficacy of refractive surgery, 0.99 ± 0.11; safety, 1.00 ± 0.05; predictabilities at ±0.5 and ± 1.0 diopters, 97% and 100%, respectively. Conclusions: Myopic astigmatism correction using the SmartSight method was effective, safe, and predictable in terms of visual outcomes.

Taxonomic Note on Nannastacus nyctagineus (Crustacea: Cumacea: Nannastacidae) from Korean Waters

이창목,김성현,김영효 한국동물분류학회 2016 Animal Systematics, Evolution and Diversity Vol.32 No.1

Korean nannastacids have recorded only eight species belonging to genera Campylaspis and Cumella. In this paper, Nannastacus nyctagineus Gamȏ, 1962, is redescribed and illustrated as a new species of Korean fauna in this study for the first time. Korean female specimens of Nannastacus nyctagineus correspond well with the original description by Gamȏ, 1962 based on only female specimens. Gamȏ has described that new species, Nannastacus pruinosus could be distinguished from N. nyctagineus based on only male specimens. The Korean male specimens of N. nyctagineus undoubtedly match well with the description of N. pruinosus with the following common features: the surface of the carapace is covered with numerous granules; pereonites and pleonites have similar patterns of the teeth on dorsal surface; the proportion and armature of the dactylus of pereopod 2 is similar; the number and pattern arrangement of the setae on the surface in antenna 1, pereopod 1, and uropod are the all most same. Nannastacus pruinosus Gamȏ, 1962 is proposed as a synonym of N. nyctagineus described in this study. This represents the first record on the genus Nannastacus from Korea.

A New Record of Campylaspis fusiformis (Crustacea: Cumacea: Nannastacidae) from Korea

이창목,홍순상,이경숙 한국동물분류학회 2012 Animal Systematics, Evolution and Diversity Vol.28 No.1

This study dealt with cumacean specimens collected from the shallow waters of the South Sea and East Sea,Korea. Campylaspis fusiformis Gamoˆ, 1960 belonging to the family Nannastacidae is newly recorded to Korean fauna. This species resembles C. pumila and C. striata in having a similar body form and a pair of narrow lateral sulcuses on the carapace, but it is easily distinguished from them by the dactylus of the pereopod 2which is more than 3.5 times the length of the propodus and bears many setae (about 20) on the surface. This species mainly occurs in the Korean and Japanese waters.

An Efficient Performance Analysis for Reinforcing Traffic Management of Campus Network

이창목,최동운 한국엔터테인먼트산업학회 2012 한국엔터테인먼트산업학회논문지 Vol.6 No.3

As the internet technology develops the number of both internet users and the usage are explosively increasing. The networking traffic is increasing in the campus as the networking system inside universities, following the trend, adds more PCs and various networking services. Nevertheless, the quality of services for users has been degraded. Accordingly, core problems, which can cause troubles for network management, design and expansion of the network, and the cost policy, have developed. To effectively cope with the problems an analysis of a great number of technicians, tools, and budget are needed. However, it is not possible for mid and small-sized colleges to spend such a high expenditure for professional consulting. To reduce the cost and investment of creating an optimized environment, analysis of the replacement of the tools, changing the network structure, and performance analysis about capacity planning of networking is necessary. For this reason, in this paper, framework-based performance management tools are used for all steps that are related to the subject of the analysis for the network management. As the major research method, the current data in detailed categories are collected, processed, and analyzed to provide a meaningful solution to the problems. As a result we will be able to manage the network, server, and application more systematically and react efficiently to errors and degrading of performance that affect the networking tasks. Also, with the scientific and organized analyses the overall efficiency is upgraded by optimizing the cost for managing the operation of entire system.

비즈니스 컴포넌트의 상호운용성을 위한 Intermediator 패턴

이창목,유철중,장옥배,문윤호 한국컴퓨터산업학회 2001 컴퓨터産業敎育學會論文誌 Vol.2 No.4

기존의 비즈니스 컴포넌트들간의 의사소통은 Facade 패턴을 따르는 방식이었다. 그러나 Facade 패턴은 대표객체 하나만으로 소속객체 밖의 모든 객체들과의 의사소통을 전달하는 방식으로서 기존의 Interface 패턴과 거의 비슷하며, 반드시 대표객체를 통해서만 의사소통이 가능하므로 여러 객체들의 동시 접근 시 과부하로 인하여 결과 반환에 속도저하의 단점을 가지고 있다. 따라서 본 논문에서 제안한 intermediator 패턴은 이러한 과부하 현상으로 인한 저효율성의 컴포넌트 의사소통 방식을 개선하여 여러 인터페이스를 통한 속도저하의 단점을 보완하였고, Intermediator 객체내의 메소드 구체화를 통하여 실제 행위만을 관리하는 Intermediator 객체를 두어 모든 행위는 Intermediator에서 이루어지도록 하였다. 그렇기 때문에 본 논문에서 제안한 Intermediator 패턴은 객체간의 결합도를 줄일 수 있고 또한 응집력은 높일 수 있으며, 다른 여러 객체들의 참조에도 여러 인터페이스를 통하여 유연하게 대처할 수 있다는 장점이 있다. Software design patterns are reusable solutions to recurring problems that occur during software development. As programmers gain experience, they recognize the similarity of new problems to problems they have solved before. With even more experience, they recognize that solutions for similar problems follow recurring patterns. In this paper, as one of these reusable design-patterns, the Intermediator pattern for the efficient communication between business component is designed and implemented. Existent business components were way that follow Facade pattern. But Facade pattern is almost like the existing Interface pattern in that the communication of all the object outside the set is done by only one representative object, and this causes the traffic system to be overloaded. Therefore, the Intermediator pattern supplements the traffic overloads by improving the inefficient system of business components' communication through multi-interface, and make all communication behavior between objects done by Intermediator object which controls all actual behavior by way of Intermediator method implementation. Consequently, the Intermediator pattern is designed and implemented in this paper can bring down the level of coupling and raise the cohesion among objects, and refer to many of other object flexibly through several interfaces.

효율적인 비즈니스 프로세스 관리를 위한 J2EE 기반 B2Bi 협업 워크플로우 시스템 설계 및 구현

이창목,장옥배,Lee, Chang-Mog,Chang, Ok-Bae 한국정보처리학회 2007 정보처리학회논문지D Vol.14 No.1

본 논문은 비즈니스 프로세스와 업무 로직을 분리하여 비즈니스 프로세스를 손쉽게 모델링하고 이를 바탕으로 협업을 가능하게 하는 B2Bi 협업 워크플로우 모델링 시스템을 설계 및 구현하였다. 협업 워크플로우 모델링 시스템은 비즈니스 프로세스 모델링 도구, 실행 엔진, 모니터링 도구 3개의 컴포넌트로 구성되어있다. 첫째, 비즈니스 프로세스 모델링 도구는 애플리케이션의 비즈니스 로직을 신속, 정확하게 반영하는 프로세스 맵을 구축하는데 사용된다. 둘째, 실행 엔진은 비즈니스 프로세스 인스턴스를 위한 실시간 실행 환경을 제공한다. 셋째, 모니터링 도구는 현재 진행되고 있는 비즈니스 프로세스에 대한 실시간 모니터링 기능을 제공한다. 또한 기존 시스템인 레거시 시스템과의 연동을 위해 XML 및 J2EE 기반으로 유연성, 확장성을 지원할 수 있도록 하였으며 새로운 기업 전략과 운용에 필요한 해결책을 제시한다. In this paper, the business process was easily modeled by distinguishing between the business process and work logic. Based on this model, B2Bi collaboration Workflow modeling tool, which facilitates collaboration, was designed and implemented. The collaboration workflow modeling tool consists of 3 components; business process modeling tool, execution engine and monitoring tool. First, a business process modeling tool is used to build a process map that reflects the business logic of an application in a quick and accurate manner. Second an execution engine provides a real-time execution environment for business process instance. Third, a monitoring tool provides a real-time monitoring function for the business process that is in operation at the time. In addition to this, it supports flexibility and expandability based on XML and J2EE for the linkage with the legacy system that was used previously, and suggests a solution for a new corporate strategy and operation.
