We propose a new coherent optical receiver (COR) to detect optical receiver mode (ORM) subchannels selectively in coherent optical (CO) ORM division multiplexing (ORMDM) systems. In the CO-ORMDM systems, each optical channel is a linear sum of ORM subchannels, to obtain high spectral efficiencies (SEs). The COR uses an ORM subcarrier as its local oscillator (LO) and reads the transmitted data at the origin times of ORM signals. For example, if the m^th ORM subcarrier is used as the LO, then the COR reads the data of the m^th ORM subchannel. The proposed COR is fast and can make CO-ORMDM systems useful for real-time optical communication with high SE.

A particular optical receiver has its own optical receiver modes (ORMs) determined by its optical and electrical filters. Superposing the ORM waveforms at the transmitter, we can generate a new type of optical signals, called ORM signals. After optical detection, they produce pre-specified voltage waveforms accurately, which is advantageous for digital signal processing. Assuming a Gaussian optical receiver, where the optical and electrical filters are Gaussian, we illustrate various phase-shift keying ORM signals using two ORMs by changing their relative phase. We also illustrate multi-level ORM signal patterns using two or more ORMs.

The method for investigating the retention behavior and separation optimization was studied to develop a reversed-phase liquid chromatography of eleven thiocarbamates that are used as herbicides. As an isocratic elution system, the statistical simplex technique was applied to find the optimum separation conditions. The resolution was quantitatively evaluated by using COF and ORM method. For thiocarbamate herbicides in which the elution order varies dramatically with solvent composition, the ORM method gave better result than the COF method. For the solvent composition of mobile phase in the ORM method, the ratio of methanol : acetonitrile : tetrahydrofuran : water was 16 : 29 : 2 : 53. Also in this research, an adjusted COF $(\overline{COF})$ method was proposed to rectify the defect in the current COF method, and the compositional ratio of mobile phase containing methanol : acetonitrile : water was 29.5 : 21.5 : 49.0 result of which is similar to that obtained by the ORM method.

This paper presents a theoretical research framework that was used to analyse operational risk management (ORM) system practices in Australia. It provides a new perspective on how to use national and international operational management system standards as a basis for systematic management of operational risks. Based on the extensive literature review and the analysis of operational risk management system practices that are common in Australian organisations, this paper identifies the critical factors for effective use of an ORM system. The proposed framework could also be used as a model to research ORM system applications in other countries.

Web-based Enterprise Intranet System is developed Object-oriented programming language and data management is constructed using RDBMS. Between Object-oriented programming language and RDBMS bring about "Object-Relational Impedance Mismatch" due to heterogeneous paradigm. To solve this kinds of problems commonly use the ORM Framework that it is converting data between incompatible type systems in databases and object-oriented programming languages, uses complex mapping metadata. It causes difficult to develop and maintain because of inflexible in changes. This paper proposed persistence framework that solve the existing complexity of ORM framework and has more flexible in evolution of database table. This persistence framework is unnecessary meta information that connecting with entity of database table and the objects, it offers users convenience of maintenance and it allows far more flexible and affordable systems to be built because of automatically code generation. The result of testing based on the proposed persistence framework with Hibernate, iBATIS, It is similar response time with iBATIS and it has more about three times faster than Hibernate. But iBATIS has problems of mass data processing.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to Hibernate 3.2 and iBatis 2.3 in same platform of Spring framework 2.5. Currently in production until the lightweight container architecture, known most commonly used architecture framework is Spring framework. Also intended to increase the productivity of database techniques are ORM. Hibernate and iBatis is an ORM tool is currently being used. In this study, Spring framework 2.5 is based on the framework of the same Hibernate 3.2 and iBatis 2.3 to design and implement the pilot system. In addition, comparison and standardization of software development productivity assessment is to provide guidance.

Recently the development of GIS and spatial information technology is used to construct very detail forest information. In addition, in order to classify forest characteristic, the geographical characteristic information of forest could be very useful for the forest classification, In this study sampling points were arranged to clarify the difference between the orm area and the land forest area. Also, forest feature pattern could be discriminated by using satellite images and SML. This study result should be constructed to efficiency forest management in especially forest area in Jeju Island

웹기반 기업형 어플리케이션은 객체지향 언어로 개발되고, 데이터의 관리는 RDB(Relational Database)를 이용하여 구축된다. 두 시스템은 이질적 패러다임에 기인하여 모델의 불일치성(object-relational impedance mismatch)을 발생시킨다. 이 문제를 해결하고자 사용되는 객체-관계 매핑 프레임워크(ORM-Framework)는 RDB 의 테이블과 객체지향 언어의 객체를 매핑하는 구조로 복잡한 메타정보를 이용하여 동적으로 매핑하기 때문에 개발이 복잡하고, 변경에 유연하지 못하여 유지보수에 많은 어려움이 있다. 본 논문에서는 기존 ORM 프레임웍크의 복잡성을 해소하고, 변경에 유연한 퍼시스턴스 프레임워크를 제안한다. 제안되는 프레임워크는 SQL 을 래핑하는 구조로 테이블과 객체의 메타정보가 불필요하고, 정형화된 구조를 가진 래퍼의 사용으로 소스코드를 자동 생성하여 개발 및 유지보수의 편의성을 제공하고, 변경에 유연하다. 제안 프레임워크는 Hibernate, iBATIS 와의 테스트 결과 구동 매커니즘이 거의 동일한 iBATIS 와는 처리속도가 비슷했고, Hibernate 의 약 3 배 빠른 속도를 보였다. 코딩량은 Hibernate 대비 1/9, iBATIS 대비 1/4 을 나타냈다.
