Robustness Algorithms for the Airport Gate Assignment Problem
Assigning commercial flights to available airport gates can have a major impact on the efficiency of flight schedules as well as on the level of passenger satisfaction with the service. These assignments also depend on the service requirements of flights and the capacity of stand facilities. Unexpected changes also called perturbations, like those due to air traffic delays, severe weather conditions, or equipment failures, may disrupt the initial assignments and increase the difficulty of maintaining smooth operations, which will detrimentally affect costumer satisfaction. The provision of solutions which reduce the potential detrimental effect of perturbations in the stands already assigned on the day of operation is desirable and some approaches are presented here, and compare between them to help identify their performance and trends

Constructive and evolutionary algorithms for airport baggage sorting station and gate assignment problems
Correct assignment of airport resources can greatly affect the quality of service which airlines and airports provide to their customers. Good assignments can help airlines and airports to keep to published schedules, by minimising changes in these schedules and reducing delays. Given the expected increases in civil air traffic, the complexities of resource scheduling and assignment continue to increase. For this reason, as well as the dynamic nature of the problems, scheduling and assignment are becoming increasingly more difficult.
The assignment of baggage sorting stations to flights is one of the resource assignment problems at an airport, and like many other real world optimisation problems, it naturally has several objectives, which conflict with each other. A model of the problem is presented, different approaches to obtaining good solutions are looked at and studied to gain an insight into their qualities. Furthermore, algorithms are studied to improve the already good solutions obtained by the approaches considered and their performance is studied where some characteristics of the problem change, such as the number of baggage sorting stations or the topology of the airport.
Changes to the flight schedule on the day of operation may invalidate previous assignments of flights to resources. These perturbations may not only affect the disrupted flights but also other flights already assigned. Some existing approaches are looked at, and others are suggested to take account of these potential perturbations at the time the assignments are generated with the aim of mitigating their detrimental effect on the day of operation.
The constructive search algorithms and robustness methods are potentially important in a wider variety of problems other than the Airport Baggage Sorting Station Assignment Problem (ABSSAP). By way of illustration, the same techniques are applied to the widely studied Airport Gate Assignment Problem (AGAP)

Estrategia didáctica para el desarrollo del proceso de construcción de textos escritos, con el uso de obras plásticas
El proceso de construcción de textos escritos continúa siendo un problema en la enseñanza de la lengua materna; dado, fundamentalmente, por el insuficiente empleo de diferentes vías para estimular la construcción de textos escritos. Los estudiantes presentan limitaciones en dicho proceso; se trazó el objetivo de: Elaborar una estrategia didáctica que contribuya al desarrollo del proceso de construcción de textos escritos, con el uso de obras plásticas, en los estudiantes del grupo II-C de primer año de la carrera PGISB de la UCP: “Rafael María de Mendive”, de Pinar del Río”. Esta investigación favoreció el desarrollo del proceso de construcción de textos escritos, a partir de la implementación de las acciones diseñada
La motivación profesional hacia la especialidad Agronomía en estudiantes de segundo año del centro politécnico Combate Tumbas de Estorino
El presente trabajo se desarrolla teniendo como objetivo fundamental diseñar un sistema de actividades que contribuya a la motivación profesional de estos estudiantes. Las bases teóricas conceptuales metodológicas de este trabajo se sustentan de manera esencial en la teoría de la Pedagogía Profesional, y en lo histórico
cultural. Para ello se utilizan una serie de métodos que posibilitaron el conocimiento de leyes, principios y categorías universales para operar en la realidad, así como el estudio de la trayectoria del problema en el cursar de la historia y la tabulación de los resultados esperados. Además se aplicaran técnicas que

Pengaruh Karoushi Terhadap Perkembangan Sumber Daya Manusia di Jepang
Abstrak Ada banyak fenomena yang terjadi di Jepang. Salah satu fenomena yang terkenal ialah karoushi. Karoushi merupakan suatu istilah yang bisa diartikan sebagai kematian dikarenakan kelebihan bekerja. Istilah ini sering digunakan di kalangan salaryman di Jepang. Jam kerja yang panjang merupakan salah satu faktor yang menjadi pemicu dalam fenomena karoushi ini. Fenomena karoushi ini telah terjadi sejak tahun 1960-an dan masih terus terjadi hingga saat ini. Fenomena ini juga banyak menimbulkan dampak bagi negara Jepang itu sendiri.Dalam penelitian kali ini, penulis menggunakan metode penelitian deskriptif, yaitu metode penelitian yang menggambarkan suatu fenomena yang terjadi, baik di masa sekarang maupun di masa lampau.Kata kunci: karoushi, etos kerja, salaryman, stres, kerja lembur, loyalita
Tumor markers in breast cancer - European Group on Tumor Markers recommendations
Recommendations are presented for the routine clinical use of serum and tissue-based markers in the diagnosis and management of patients with breast cancer. Their low sensitivity and specificity preclude the use of serum markers such as the MUC-1 mucin glycoproteins ( CA 15.3, BR 27.29) and carcinoembryonic antigen in the diagnosis of early breast cancer. However, serial measurement of these markers can result in the early detection of recurrent disease as well as indicate the efficacy of therapy. Of the tissue-based markers, measurement of estrogen and progesterone receptors is mandatory in the selection of patients for treatment with hormone therapy, while HER-2 is essential in selecting patients with advanced breast cancer for treatment with Herceptin ( trastuzumab). Urokinase plasminogen activator and plasminogen activator inhibitor 1 are recently validated prognostic markers for lymph node-negative breast cancer patients and thus may be of value in selecting node-negative patients that do not require adjuvant chemotherapy.
